Hope Hub bearing
07 September 2022  | 

One of the bearings in my Hope 4 hub was running rough. Rather than pay Hope's premium price for a bearing I installed one of these which fitted and works perfectly.

Once again quality bearings from Wych, I have replaced the original bearings on my bikes with these and they always run well and last longer than those used by the manufacturers so can’t fault them at all. The price is good as well

Hope wheels.

After a quick chat with one of the friendly staff to identify the differences with some of the bearing options for my Hope Hubs ive gone for the Abec5 LLB, Only been out shredding at Bike Park Wales once since fitting them, I must admit, they do feel much nicer than the standard Hope Bearings, ill see how they hold up for this seasons riding.

Super quick delivery and availability of these bearings - used from front hub on Fulcrum Racing 5s. Hopefully better than the originals fitted at production that lasted only a few months before water ingress destroyed them.

Quick delivery and smooth running bearing

Delivery was really quiet. The new bearings are noticeably quicker and smoother running than the stock bearings originally installed in my mavic wheel set. Would recommend, will be ordering from Wych bearing again in the future.
