Hope Mono Rear Hub
The MONO hub available from Hope comes in either a steel or titanium cassette body and has sealed cartridge bearings. We have liked Hope hubs for a while mainly for the fact that they are designed with sealed bearing to make it easy to service.

They defiantly look the part machined from one piece they look clean and solid. We built these up onto Mavic XC7171 rims with conventional V-brakes. The reliability from the hope brand has always been good so these are no exception, we used these fro several months clocking up a lot of miles and they were still silky smooth at the end. We have heard reports that they can be noisy but we found them to be ok.
They weigh in at around 355g making them ideal for XC. Overall they are a solid design at a good price, the cartridge bearings are a piece of cake but they are so reliable you shouldn’t be taking them apart too often.
