My Pro 4 hubs have done 7 years and 13,000km on the original bearings. Sadly the bike they were on was stolen at the weekend
Lovely.
Sadly, mine we less reliable than my pro2s, requiring DS hub body and freehub bearings every year. Then the advent of 50t cassettes meant the torque I exerted on the axle deflected it far enough to have the drive ring bite into the free hub body and crunch pawls to bits because they weren’t engaging straight, effectively ending their use as a viable hub for me.
I’m somewhere in the middle – had my Pro4’s since late 2018 and not broken much in it – other than a couple of pawl springs – and it needed new hub and freehub bearings last year.
To be fair I’d properly neglected them and it was a right state inside the freehub body with dirt and grime and it was all clogged up. I found it quite easy to clean it up / change the springs for new ones / change bearings and they’re good as new again.
Although I would like to slap the person who designed the microspline freehub body with a bearing sat deep inside – held by a circlip sort of thing with no holes and just 1 small ‘tail’ to try and grab it by to remove. Grrrrrr.
Would like to try the Pro5 to see what it sounds like – but I just don’t need a new hub at the moment and £££££
