    I understand the point of that thing, and the principles behind it. but I don’t care even if I was a serious racer, you couldn’t pay me to ride that unless they seriously improve the aesthetics somehow.

    it looks like a regular road bike was destroyed in a crash, and Spiderman rebuilt it. even for as big a Spiderman fanatic as me, no thanks.

  • Eric C says:

    Interesting idea. Although I’d like to see how it does on descents, crosswinds, rain, snow, etc. Meanwhile, I’ll stick with my awesome Serotta HSG carbon. A real frame.

  • Tom Chang says:

    I can understand people’s skepticism. I was a skeptic until I rode it. With this frame you can honestly tell the difference between stiff and effiecient. As soon as I rode the Ascend, I could accelerate much fast than my Ridley Noah. In fact, the Ascend with a 53/39 and 11-23 felt just like my normal 50/34 with 12-25. I also have owned and ridden several carbon frames (Serotta HSG, Parlee, Ridley and Cervelo), but this was a much quicker and better handling bike. By the way, I weigh 195lbs and am sprinter.

    I agree with Brian that the aesthetics and emotional aspect is not there but the ride is phenomenal. I would invite Eric to ride one.

    My brother and I are both former racers. There is a climb near our house that we have done many times, with 6-10 percent grades, and over 2,000 feet of climbing. I got a chance to demo the Ascend today. Despite the fact that we had to ride in the afternoon in 100 degree temps, and didn’t have the tail wind we have had lately, I still beat my best time this year by over 1 minute 30 seconds. If I had gone in the morning with cooler temps, I have no doubt I would have gone at least another 30 seconds faster (the heat killed me). This bike is so stiff, it is unbelieveable! You get out of the saddle, and there is a transfer of power to the wheel that is like nothing I have ever felt. After reaching the top, my brother and I switched bikes, and did the last steep sections again. This time I was on his Specialized Rubaix with Dura Ace, and he was on the Ascend. The Rubaix felt like it had a flat tire by comparison. My brother could not believe the difference, and after 2 days of giving me crap for considering upgrading my bike, suddenly was trying to figure out how to afford one too. If you live in the mountains, don’t try this bike unless you are ready to buy. Everything else will feel like a wet noodle afterwards. Oh, and my bathroom scale said this incredible, stiff bike, only weighed 14.5 lbs with water bottle cage :) It may be ugly to some, but it will be the future of bike racing. It gives a huge advantage to the climber on it, and with lots of money and fame at stake, serious riders will have no choice but to get on!

  • Rick DalCanto says:

    I’ve gotten three more rides in on the Ascend. My biggest criticism is that the ride was a little harsh with the straight, aluminum, Thompson seat post that was on my demo bike. I switched it out for an Easton EC70 carbon post with 25mm of layback, and it made a world of difference (the layback also gave me more room in the cockpit which I needed as the bikes run small without it). I still can’t get over how much faster I climb now. Not only did I keep up with my brother, who is 30lbs lighter than me, on a long climb on Sunday, but I actually was able to sprint around him and beat him to the top (which has never happened before)! With regards to the looks, it is much cooler in person, and a huge hit with everyone that sees it. If you ride it, be prepared to answer lots of questions and feel like a celebrity.

    Interesting concept, though i hope not to get into a scoff with a local rider equipped with wire cutters, or ride through thick mud on the mountain frame, that would turn that light frame into a pig. Good luck cleaning that thing. P.S.- how about a video proving the strength of the frames, or lack thereof.

  • David Guenette says:

    I ride an Ascend and have to say it is the best ride I have ever had. It is fast, very stiff and great on climbs. It also corners well and I was able to appreciate how fantastic this bike while racing at the Sea Otter a few weeks ago.

    Depending on your personality, you will either welcome or get fed up with the constant attention the bike brings. People love bikes so I enjoy the conversation (at times). The most common comment I hear is, “I have never seen one of those before.” And the cleaning part is the easiest part. This bike only requires a mere wipedown of the frame and as anybody should, I keep everything else dirt free. The only problem is, I want another one.
