Step 1. Before removing your old saddle, record two measurements
1a. Saddle height from the top of the saddle to the center of the bottom bracket.
1b. Widest area of saddle to center of handlebars.

Step 2. Measure Your Sit Bones
Obtaining a width measurement for your sit bones (ischial tuberosities) can be useful for establishing a rear saddle width. Most bicycle shops have tools to measure your sit bones, but you can also get a measurement at home using very simple tools and just a few minutes of your time.
Place a piece of clean cardboard on to a hard surface. While sitting pull yourself firmly down on to it. This will leave impressions of your sitbones in the cardboard.Be sure to sit upright and do not wear thick padded clothing.
Use a dark colored crayon to rub across the surface of the cardboard (using the side of the crayon with paper sleeve removed)– this will reveal your sit bone indentations. Mark the center of each indentation.
Use a ruler or tape measure to determine the distance(in millimeters) between the center of the sit bones.Write this number down because you will use it to set the rear width of your saddle.
Step 3. Setting Up BiSaddle Width
Every BiSaddle leaves our factory with a neutral position that works well for a variety of people. If you’re new to BiSaddle and not sure what you want or need, try this setting first. If you have experience with another saddle and know of specific measurements that you’d like, feel free to adjust to those settings.
REAR ADJUSTMENT: In general, most people prefer a rear width of BiSaddle that’s equal or slightly greater (1cm – 4cm) than their sit bone measurement.To make the adjustment, loosen rear bolts on the underside of BiSaddle and use your sit bone measurement to establish the proper width. The width of the widest point of your BiSaddle should match the width you recorded when measuring your sit bones. Tighten bolts after adjustment is made. Keep surfaces symmetrical unless asymmetry is needed. Using your sit bone measurement to adjust the rear width is meant to be a starting point for achieving comfort. You may find a slightly more narrow or wide saddle adjustment is most comfortable for you.
FRONT ADJUSTMENT: The front width of your BiSaddle is largely up to personal preference. A wider front typically results in better blood flow and/or reduction of genital numbness. If it’s too wide, however, it can cause rubbing or chafing of your inner thighs. We suggest that you set the front of the seat as wide as possible without chafing.
How To adjust width: Loosen (but don’t remove) bottom bolts using the supplied Allen wrench. Adjust the seating surfaces to your desired width, and re-tighten bolts. Double check that both sides are symmetrical and tighten to 3 Nm. Fine tuning adjustments can be made on the trail. We recommend adding the supplied allen wrench to your tool bag. MAX BiSaddle bolt torque is 26 inch/lb or 3Nm.
Note: Do NOT adjust/loosen the nose bolt in the chassis - it secures the rails!
Rear Adjustment: Adjust rear width to match your sit bone measurement. Remember to add your riding position. Measure to the widest point of your BiSaddle and tighten bolts to 3Nm.
Front Adjustment: Start wide and reduce width until the saddle no longer rubs on your inner thigh.
Step 4. Installing BiSaddle on Your Bike
Fore-aft: To set the fore-aft adjustment, replicate your old seat measurement from the widest point of the saddle to the center of the stem clamp.
Height: Install BiSaddle and lightly tighten your seat post bolts, while still allowing for some movement and adjustments. Set the saddle height to match your previous seat height.
Tilt: Most cyclists prefer a seat that is level to their bike or slightly tilted downwards. When setting the tilt of your seat be sure your bike is on level ground and use a level to set the seat to your desired tilt.Small adjustments to tilt can often help you achieve ultimate comfort.
DOUBLE CHECK THAT ALL BOLTS ARE TIGHTENED PROPERLY BEFORE RIDING YOUR BIKE!
RAIL TORQUE SPECS: Carbon Rails: 6-10 Nm,6-8 Nm for 2-bolt, 9-10 Nm for single bolt
MAX BiSaddle bolt torque is 26 inch/lb or 3 Nm.
Do NOT adjust/loosen the nose bolt in the chassis - it secures the rails!
Bring the supplied Allen wrench along with any other necessary tools on your first few rides, as some small adjustments may be necessary to get the position 100% dialed in. Often times a small adjustment in height, tilt, or fore-aft can make a big difference in comfort. Also feel free to experiment with the saddle width, always making sure to carefully adjust it and properly tighten the bolts before riding again.
Step A. Optional Profile Wedges
Wedges are an optional add-on to your BiSaddle purchase. They are available here. These can be installed between the base of the saddle and the two saddle surface pads to change the shape across the saddle top. Making it either more flat, or more rounded. Note: Only use wedges if you are unable to get comfortable with a standard BiSaddle setup.
Wedge Screws: Longer screws are needed for the wedges and are included in the wedge kit.
SRT Rounding wedge: front bolts 14 mm, rear bolts 20 mm.
SRT Flattening wedge: front bolts 18 mm, rear bolts 20 mm.
EXT Rounding wedge: front bolts 14 mm, rear bolts 20 mm.
EXT Flattening wedge: front bolts 16 mm, rear bolts 20 mm.
There are no absolute rules that dictate who should use wedges. In general people with good flexibility and forward hip rotation tend to prefer a flatter saddle. People who aren’t as flexible and/or to struggle with saddle sores tend to prefer a more rounded saddle. We suggest you start with no wedges, and add them if you run into a specific problem.
Additional Instruction:
2 hole front surface nut adjustment:
Your BiSaddle may be equipped with a 2 hole front adjustment nut. You can determine if you have the 2 hole nut by removing the front bolt and looking under your BiSaddle. To adjust the front of your saddle more wide or more narrow it may be necessary to remove the front bolt and re-install it into the desired nut hole.
Optional rear bracket:
The rear bracket is optional and is only compatible with the flex frame. It will not work with the full carbon fiber frame. The rear bracket can be used to hold your bike onto a race transition bar or used to hold a water bottle or tool bag. To install the rear bracket you should place the supplied nut into the base of the frame and insert the bolt from the rear of the frame and tighten.
Removing or Changing your BiSaddle Padding/Surfaces
After riding, adjusting, and re-riding your BiSaddle, it may be desirable to try different surfaces to get fully comfortable. Alternate surfaces are available here.
All BiSaddle base frames and surfaces are interchangeable. This means you can replace your surfaces without changing the base. To remove the surfaces, all 4 adjustment bolts will need to be removed from the bottom side of the base frame. Once all the bolts are removed, you can proceed to install the new surfaces on to the frame and re-install the bolts. Please make sure the bolts are tightened before riding.
Bolt sizes for surfaces
SRT 1.0, Saint, Saint Pro 3D, Hurricane, Hurricane Pro 3D
Front adjustment bolts: 14mm
Rear Adjustment bolts: 16mm
Stealth, Bonneville, Sprint
Front adjustment bolts: 12mm
Rear adjustment bolts: 16mm
TROUBLESHOOTING:
Surfaces are moving while riding: If after long rides you find that the surface shave moved, then reposition them to your desired width and tighten bolts down beyond 3 Nm and re-ride. Tighten bolts until the surfaces stop moving.
Asymmetry: Some cyclists may need the saddle surfaces asymmetrical to get comfortable. This means one side may be adjusted differently than the other to provide comfort for those with hip alignment issues or injuries.
Sit bones rolling off the inside or outside of saddle: If your sit bones are rolling off the inside of the saddle surface, then try adjusting the rear width of your saddle a little narrower. If your sit bones are rolling off the outside of your saddle surface, then try adjusting the rear width of your saddle a little wider. Note: You may also want to try lowering your saddle height. If your saddle is too high and your legs are over extended, then your body will be forced to roll side to side to stay on your pedals.
Tailbone pain: Try adjusting the rear width to a wider position to allow room for the tailbone.
Making contact with flex frame base: If while riding you are making contact with the flex frame base, then try a wedge to raise the surfaces. If after trying the wedges you are still making contact with the frame, then contact us to discuss the option of trying a rigid carbon fiber frame.
Race transition mounting problems: BiSaddle is considered a noseless saddle, which can make it difficult to keep your bike on the transition bar when held by the nose. We recommend using a zip tie or velcro strap to hold your bike on to a race transition bar.
BiSaddle seems confusing: Don’t give up. Your ultimate custom fit saddle may be just a small adjustment away. Try learning a little more from our videos at bisaddle.com/pages/instruction or call us to see if you qualify for a free saddle surface trade.
Unable to get comfortable: If you have tried multiple widths and wedges and still cannot get comfortable, then please call us for further troubleshooting at (877) 397-2165. When adjusting your BiSaddle, Always let comfort be your guide!
WARRANTY:Your BiSaddle comes with a 1 year warranty on the surface padding and a lifetime warranty on the base frame against manufacturer defects and only applies to the original owner. Wear and tear is not considered a defect. Please contact us if you feel there is a defect with your BiSaddle. hello@bisaddle.com or (877) 397-2165

“Usually the pain begins after 3 miles, and boy do I hate bumps of any kind!”
Pain can be experienced when body weight is supported by the soft tissue between your sit bones.
“After 10-15 miles, I would develop numbness”
Bike saddles can cause men and women to put pressure on the perineum, which is the area located between the external genitals and the anus. This pressure causes arteries and nerves to compress, resulting in reduced blood flow and sensation to your genitals.
“I have tried an exhausting number of bicycle seats and haven’t found a comfortable saddle”
Saddle padding shouldn’t be excessively thick or soft. This causes the padding to squish down under the sit bones – and pushes up in the middle – adding pressure and discomfort where you don’t want it.
“I had trouble with numbness and saddle sores while in aero position”
When you ride in the drops or in aero position your pelvis tilts forward (three degrees more for women then men), which can take pressure off the sit bones and can re-distribute it on soft tissue area causing sores and numbness.
“I was holding back on extra and long distance rides because I was worried about “ED”
“There are only two kinds of male cyclists – those who are impotent and those who will be impotent.” – Dr. Irwin Goldstein
“I was miserable on my saddle and developed certain “female” issues”
A recent article indicated that 30% of the professional female riders the author knew, required genital surgery from damage due to saddle pressure.

Overall rating: 4.7 / 5 from 126 reviews.
The saddle was very easy to adjust, and I found it straightforward to get accustomed to my new saddle. Overall, I no longer experience soreness in my rear as I did with my old saddle. I can now ride for 3 to 4 hours without feeling fatigued. Unfortunately, I can't say the same for my hands on the handlebars!
I love my EXT Sprint Road, very comfortable and despite the extra foam padding is still firm (I was concerned I might sink into the seat). The complete center channel is a welcome relief on my sensitive areas. I ordered and installed the seat just before leaving for a 7 day 470 mile cycling event. I don't recommend heading out for such a long ride without prior experience with a new saddle but I'm happy to say it worked just fine and a big improvement over my old saddle. I also like the fact the seat is adjustable, who wants to pay for a collection of failed saddles when instead you can tweak your saddle until it's just right for you.
The EXT Sprint Road saddle has been a great improvement, and perhaps as I become more accustomed to it, at a future time may not have any soreness, but right now there's still some irritated areas -- even though I've adjusted the saddle three times. I feel that 30 days is not enough time to really test a new saddle, and to claim to be pain-free is just too good to be true. When I changed from the 3D Saint Pro to the EXT Sprint Road saddle it left some sharp edges under the rear of the frame. Is there anything I can do to remove those sharp bumps?
Great saddle. Couple more little adjustments and it will be perfect. Comfy too
Dig the bike seat, feel it eliminates pain to soft tissue areas.
Pictures of the Hotter than Hell 100 Wichita Falls Tx ! My Bi-saddle made the ride less painful and the comfort was great ! Thanks
Love the Bisaddle EXT Sprint Road. It took a little time to find a comfortable width. The addition of the Wedge Kit 2 made all the different. My sore rear end and tender tissue are finally a thing of the past. I love this saddle so much I have recently purchased 2 more Bisaddles for my other bikes. I also found customer service to be very helpful.
I was getting chafing where your glutes meet your hamstring--even my chamois threading was coming wearing out there. My friend sent me the Bi-Saddle information. It was not inexpensive, but since there's a 90 day return policy, I figured I had nothing to lose--I wanted to do longer rides and not be held back by my saddle. I was starting to hurt after just an hour on my previous saddle. A week ago, I did a 60 miler and it felt great--I even rode 17 the next day! I highly recommend--instructions are great and it's easy to set up. Can't wait to get one for my mountain bike!
My bi-saddle has allowed me to focus on and enjoy my ride, instead of persevering through discomfort during my ride. The saddle change has made a real difference!
After receiving the saddle, I followed the instructions and tried it out. After a few minor adjustments and a half dozen ride later, I'm VERY happy with the saddle's performance. The soft tissue pressure I've experienced over the last few years is gone. Thank you for such an intelligent, flexible design.
This has been the best and most comfortable saddle I have ever used. The change in comfort and feeling happier on longer bike rides was immediate. I couldn't be more pleased with the product and I'm telling everyone I know about the incredible positive difference it makes. What is amazing is not just how good the riding experience with it is, but later at night and the next day your bum or inner thighs don't feel a thing! There is zero soreness to recover from before you feel like riding again. I wish I knew about this saddle years ago.
I just completed my 1st Bike NY 5 Boros Tour with my new bisaddle. I had ZERO pain in my sits bones- no bruised feelings at ALL!🔥🙌🏽💜🚴🏽♂️💯. I’m looking forward to completing my first century ride and many more biking events! Thank you sooo much. Being able to adjust my saddle to my body has made all the difference!🙏🏽🙏🏽
Feels good 👍 I like the fact that I can adjust the size of my seat at a comfortable status, my butt is happy 😊
A great saddle! I had the original BiSaddle over 20 years ago! This is a much more refined and higher quality product. Difference between this and a standard saddle is Miles apart. No pain, massive gain!
I hesitated spending the money on this saddle but went ahead. My previous Fabric saddle was not comfortable on rides longer than 20 miles. When I received the BiSaddle I kept the factory positions and installed it on my Canyon Endurace bike. It took a few rides to get use to the different shape and adjust the height due to the thicker seat. Once I got the height set bike rides are now more comfortable for rides 40+ miles. Now I am considering buying another BiSaddle for my other bike.
I got this saddle after having unbearable discomfort from a traditional saddle on the trainer. I give the saddle 4 stars for ease of install because although it’s not hard to install it’s not going to be something that you can just plop on and forget about. It took me about 3-4 rides to get mine fine tuned, but the effort is well worth it! No more pain or numbness in the crotch area! I will be investing in a second one for my mtb!
Overall the saddle is fine. It’s a little creaky but quiets down after a few minutes. Padding is softer than I’m used to. I’ve adjusted it a few times and that helped. We’ll see how it goes.

Really great saddle. Endless amount of small adjustments you can continue to do to make yourself more comfortable on long rides.
Noticeably more comfortable ride. There are so many different ways to do minor tweaks after install that it was easy to adjust to perfection. Definitely recommend!
The saddle is amazing! I need to make some minor adjustments but I have no complaints at all. I plan purchasing one for my hybrid bike soon. Thank you. Will J.
My bottom is loving it
Before getting the Bisaddle, I could not ride more than 20 miles without my sit bones being in extreme pain. I would push through just to get 30 miles. Now I can ride 40+ miles without any pain. The comfort is amazing! I highly recommend getting one.
5 star for soft tissue pressure relief; 3 star for adjustability; 1 star for sit bone pressure relief. I think the padding is just too stiff. Overall experience is mixed. I like it in the drops for about 2 hrs. After that, my sit bone area starts to throb. I had high hopes this would be a 5+ hour saddle. It is not.
Initially I bought the Bonneville Distance based on the product description and my riding style. I couldn’t find the proper adjustment for pain free riding with the Bonneville. The company contacted me after the first review and try to guide me through new adjustments but nothing worked. Frederique from Bisaddle contacted me and he suggested to try another model. We choose the EXT Sprint Road, and I found the proper adjustment range for a comfortable pain-free ride in 3 rides. Kudos to the company for taking the time and effort to find a solution.
good
Fanstastique ! Je ne changerai plus jamais de selle ou alors pour une bisadlle !
The seat was installed on my trainer bike. A little fiddling and I was able to get it adjusted. Comfortable for an hour of spinning. Looking forward to getting it out on the open road.
Best seat I've tried so far.
It feels great, it was definitely an improvement, it helped me to totally remove the tailbone pain after long rides. I was also experiencing major numbness down there which helped me reduce it but it didn't totally go away. I think I should have gone with the EXT Stealth instead since it has the biggest cutout. Overall happy with the purchase though.
Having the flexibility to make minor adjustments and fit exactly how I need it has been amazing! It has changed my cycling experience all together.
Great fit, nice saddle
So much more comfort than a regular seat
My lower back feels better, butt pain is less and less numbness around the groin area.
Haven't made an final assessment at this time. Still getting it adjusted correctly. Little bit of saddle rub going on currently
After 2 adjustments no pain, after the ride no pain,
Love the adjustability. Instantly noticed a difference. What a relief
I was desperate. My old saddle was making me miserable. I had been eyeing bisaddle and made a last minute swap. The saddle arrived on a Wednesday. I put it on that night and rode for 30 minutes Thursday morning. Then 3 days later, on Sunday, I raced Augusta 70.3 without any pain during the bike. This broke the "rule" of nothing new on race day. Totally worth the "risk",
Most comfortable saddle. So comfortable I bought another for one of the other garage mates. Life is good
It doent’d fit me
I’ve probably experienced the worst pain from all saddles I’ve ridden on rides over 2 hours. The extreme pain on urination was unbearable and I needed a solution. Just completed a 4 1/2 hr ride and absolutely had ZERO pain or discomfort. The adjustment on the saddle cleared a path for me and it was the most comfortable ride I’ve ever had over several hours. Just put a second one on my race bike. A little xtra weight is worth the comfort of getting to be in the drop lbs as long as I need to. Probably looking at a 3rd saddle for my other race bike so I do t have to swap back and forth. Make the purchase and you’ll never look back!! Patrick
