Everyone knows you can get cheap carbon rims (and frames, bars, seatposts etc) from China, but like you, we still have that nagging feeling in the back of our minds... how long will these rims last under hard riding conditions ('just riding along'... yeah, we know what that actually means)
The truth is that Chinese carbon is actually pretty amazing quality for the money, but it's good to get some long-term tests confirmed too. Since we're already helping Switchback Bikes to develop their next bunch of frames, we thought we'd get some carbon rims in for long-term testing. We've got four wheelsets built up and we'll report back our findings. We've got road, CX, and 29er rims (and we can get other sizes), and if you're interested, come in and have a look.
