OK then, we're off. First ride completed
Out the box they looked really nice, shiney! There is no doubt the "Extreme" badged hubs are miche, the instructions are from miche!
Fitted the cassette, ok. Then went back and added the two little spacers, still not exactly aligned to the old gearing position, no idea if they should be but a bit of fetting and the shifting was ok'ish. On the ride there was a lot of pinging in the first 500yards, but after that silence. The freehub is amazingly quiet, especially compared to the previous hope hubs! Wheels feel really good, im not sure im good enough to spot a subtle difference but they felt as stiff as the hopes they replaced. 100km later, all is fine stayed true and faultless performance on the crappy roads around the fens!
I'm impressed, cracking value for money. Will see how they get on after a few more miles.
PS - Weight wise, I think they were 1850ish the pair (without skewers or rim tape) so not light but not bad...
