On a recent business trip to China, I wanted to actually go to the factory to see the wheels made from scratch, and get that “factory direct” experience. I had a little bit of time, I reached out to Karen at ACEBIKE, and got an invite to see the carbon manufacturing process in person. ACEBIKE, I believe has been around longer than most of the fly-by-night carbon startups in China and started with carbon road rims. I got to see the cutting of the pre-preg UD carbon, mold lay-up, sanding, finishing and QC departments. I was impressed with the quality and precision of ACEBIKE’s products. From what I saw, they are the factory behind a lot of other carbon fiber bike items manufactured in Asia.
I decided to take them to Snowbird’s Big Mountain Trail above Salt Lake City. I ride from my house to the peak, which is a 7000’vertical climb. Even though they climbed better than the 25mm wide Race Face Turbine wheels, this wasn’t their strongest point. Flying downhill was a different experience with these wheels. The 35mm width added more traction and control in the straights, berms, rocky and blown out sections of the trail. The width also increased the cornering performance as well. I bested my downhill Strava time for the trail by 4 minutes! The 18-20psi in each tire was a good balance between bump compliance and having enough air in your tires to avoid damaging rock strikes. I think if you’re really aggressive or heavier, you’ll want to add a few more psi for sure.
With the sky high prices for quality carbon wheels, and new 2016 bikes spec’d with carbon wheels, I am glad I took the leap of faith on these wheels. They saved me a lot of money and run incredibly well on my Intense Carbine 29. That’s my 2 cents. Wheel link: http://www.acebike.com/mountain-bike/wheels/carbon-pro-xxr-series
