Just got a pair of Rolf Vector Pros through an ebay auction (and for just a hair over $200 with a DA cassette that aint half bad) and would like to have a look at the rear wheel bearings. They don’t seem near as smooth as the front ones. Figure it needs to be taken apart (and should be done so by a LBS mechanic) and would like to know how to go about it. Anyone?
No one ever done work on their Rolfs…or has no one ever owned a pair?
I own 2 pair but usually let my LBS do the maintenance on them. So sorry can’t be of much help.
Thanks for at least taking the time to post as much mike.
Are you looking for information as to how to do the work yourself? Or who could service them for you? Trek is responsible for Rolf wheels, and should be able to get parts, etc.
Rear hub is a Hugi, depending on the model year, the bearings are 6000, 6903, and I forget what is in the freehub. The rear hub won’t be as smooth as the front, there is LOTS more drag in those bearings not to mention the freehub body seal.
Any shop with the Hugi hub tools should be able to help you out.

I’d like to take apart (and hopefully put back together in working order) the rear hub. Seems the bearings aren’t as smooth as those on the front wheel and I’d like to know if there is any gunk in there I can clean out myself. Not a class A mechanic by any stretch but I can do just about all the work on my bike myself.
Take a look at the bontrager web site. The Rolf vector pro hubs are similar to the Bontrager Race Light Aero (but parts are not interchangable)
To disassemble the hub, all you need is a rubber mallet and a bearing punch. Leave the cassette on the freehub body, and push the cassette / freehub assembly off with your fingers, using the spokes as leverage. Use the mallet to tap the axle out the left side of the hub. use the bearing punch to remove and replace bearings.
Then put everything back where you found it.
Cool. Thanks. That the cassette body comes off so easily is a little disconcerting though. I’ll give it a try…many thanks
Its actually a really good design. Everything press fits into place well, and its impossible to misadjust anything. Impossible for anything to fall off, so have fun.
Oh yeah, check your wheels regularly. I’ve seen a bunch of the rear hub bodies crack on the Vector Pros. I think that was isolated to one year of production, when they tried to lighten up the wheel a bit too much. You should be fine, but better to be safe.
Cracked hub bodies???
Where is particular were they cracking? I’ll keep an eye out for this…wifes bike…don’t want it to look like I offed her with some faulty wheels.
Drive side hub flange, between spokes, crack line running parallel to the axle. My guess is that the hub shell wasn’t strong enough for the high spoke tension.
Jason…you are a fount of knowledge…many thanks again. No cracks on this set (and the pawls look barely worn…same for the cassette). Previous owner could have done a bit more to care for the cosmetics but then not everyone is as picky about wheels as me. Things were a little gritty in there but once I cleaned it out and regreased it things are as buttery as the front. You rule.
Hey Superdave…can the bearings in there be swapped out for another (current and maybe smoother) set? BTW…money is in the mail.
