I’m tired of having to replace the bearings of the ZIPPs too often due to water ingress. The ZR1 seem not well designed in that area. Other than that, wheels are amazingly capable and strong, I sometimes abused them like a mountain bike wheels. I don’t clean my bike using a pressure washer or something, only in the shower at low pressure. Also I never ride my bike under the rain. In two years I had to replace the bearings tree times and every time I see water inside the hub and the bearings are shot, rusty or dying.
I just ordered the new 9Velo GV35 2.0 wheels with the new ratcheted hub. I only hope that the rims itself are as strong as the ZIPPs and that the hubs are better in terms of water protection. Also the ratcheted hub vs the classic pawl system of the ZR1 is a welcome improvement as well. Additional note, the 9Velo are hooked vs the hookless ZIPP, not a problem at all for me since I didn’t have any issue at all with this system, just something to know about from the new wheels.
ZIPPs are 40 and the 9Velo are 35. They have a 45 version as well. I opted for the shallower ones because I don’t race, the 35 are lighter, less affected by the crosswinds and probably more compliant than the 45 ones.
I will update this post or make a new one when the wheels arrive and I have a chance to try them.
Maybe I’m crazy, will see. Wish me luck. 🤣
