Ad text
In 2019, a 41-year-old Ukrainian cyclist named Dmitry Kovalenko won every single ultra-endurance race he entered. Six races, six podiums, over 1,200 miles, while riders half his age were standing on their pedals every 20 minutes, grimacing in pain. Dmitry sat perfectly still for eight hours straight. No shifting, no standing, no numbness. When a reporter asked him how, Dmitry smiled and said, I just read the documents your industry refuses to. Dmitry wasn't a pro. He was a mechanical engineer. And when saddle pain ended his cycling career at 38, he didn't buy another saddle. He went to the library. He found two documents. The first, a 1968 NASA engineering brief for the Apollo Command Module seats. It said, no pressure may concentrate on soft tissue under any g-load. Astronauts would be sitting under three to four times their body weight on launch and re-entry. NASA's engineering team had to guarantee zero nerve compression, zero numbness, zero blood flow interruption. They figured it out. Twelve men landed on the moon. Every one of them came home. None of them got off the capsule numb. The second document, a 1999 federal study, the NIOSH study, that directly linked standard bicycle saddle design to nerve damage and sexual dysfunction in male cyclists. Dmitry read both. Then he looked at his $400 racing saddle and realized this. Every saddle on the market, from the $40 department store model to the $500 carbon fiber race saddle, uses the exact same pressure distribution design from 1947. NASA solved this in 1968. The government confirmed the damage in 1999. And not a single manufacturer has changed the shape. That's why you feel that tingling and numbness after some time on the bike. It's not your fitness. It's not your positioning and height. It's not even your age. It's because every saddle you've ever owned concentrates 100% of your body weight onto the soft tissue between your set bones. That tissue is packed with nerves and blood vessels. It was never designed to bear load. And here's the worst part. The 1999 NIOSH study didn't just prove that saddles cause numbness. It proved that repeated nerve compression from saddles is directly linked to chronic issues. Permanent nerve damage, erectile dysfunction, and loss of sensation that doesn't come back. And if you're over 50, it gets worse. Your soft tissue is thinner now than it was at 25. Your pelvic floor has less protection. Your nerves are more vulnerable. The same saddle you rode on for decades without major problems at 25 is now causing damage at 55 because your body doesn't have the same cushioning anymore. Every ride, you're compressing tissue that can't recover the way it used to. That's what Dimitro understood. So he did something radical. He cut open his saddle. He widened the base where his sit bones actually landed so his bones carried the weight, not his soft tissue. He carved out a full relief channel. Complete zero pressure zone over his perineal nerve and blood vessels. He added high-density memory foam to hold his sit bones on the surface. Then he wrapped it, bolted it back on, and rode 200 miles. Zero numbness, zero pain. For the first time in three years, he came home and realized, I didn't stand once. He started winning races, and when riders asked what saddle he was using, he'd show them. Hand-carved, custom-engineered saddle. Built around what NASA had proven decades ago. Get the weight off the tissue, onto the bones, where it belongs. That's why the Ascent saddle was built. It's the first saddle engineered around the same principle Dimitro discovered, and NASA and NIOSH proved. First, a wider bone platform, so your bones sit on the saddle, carrying the load the way your skeleton was designed to. Second, a full central relief channel. A complete zero pressure zone directly over your perineal nerve and blood vessels. The tissue that was being crushed on every ride, it touches nothing. Third, high-density memory foam, firm enough to hold your bones on the surface, forgiving enough to contour to your anatomy, so the load spreads evenly across the right structures and never spikes onto the wrong ones. Fourth, built-in air suspension. Every pothole, every crack in the road, absorbed before it reaches your spine. Weight on the bones, nerves protected, shocks dampened, pressure below the threshold for tissue damage. That's what NASA figured out in 1968. That's what Dimitro built in his garage in 2016. And that's what the Ascent delivers today. Over 50,000 cyclists are already riding on it. Riders who have the same graveyard of saddles you have. The bike fits, the padded shorts, the chamois cream. Riders who are standing on their pedals every 10 minutes just to survive a ride. Riders who thought a good bike fit was the only option, but they didn't know that even the best bike fit won't give results to a fundamentally broken saddle design. 89% of Ascent riders have already reported that from the first ride with the Ascent, they didn't experience any pain or tingling. Right now, the Ascent saddle is 30% off at $69. This is not a permanent price. And it comes with an ironclad 30-day ride it or return it guarantee. Not 30 days sitting in a box. 30 days of actual riding. Put it on your bike. Ride your routes. Do your group rides. If you're not completely pain-free, send it back. Full refund. No questions. The only risk is staying on the saddle you're already on. And we both know how that ends. Click the link below. https://ascent-bicycle.com/products/ascent-saddle Get the Ascent at 30% off.

The Hidden Numbness & Saddle Connection
After 2,000+ professional bike fits, one fitter stopped recommending saddles. Then he found The Ascent. The first saddle that addresses the whole system.
