new rear wheel compatible with shimano centre lock required

Big dave 3

Hi, I currently have shimano xtr m985 hubs with mavic 717 rims & sapim spokes I belioeve. The hub/frehub is nackered I believe. The wheels are 4 years old. I took them to local bike shop & they recommended just buying a new rear wheel. THey also have the shimano xtr centrelock discs.

WHat should I get to replace the wheel? It is used for commuting mainly with slicks on. I dont want to spend more than 150 as it is only a commuter bike.

ADvice gratefuly received, as im out of touch with whats a good wheel these days.

Who told you that?

New bearings, freehub if needed. You've got one of the best you can buy

I'd find a new LBS.

OK the problem is that I was with my toddler daughter who was running round the shop & I couldnt see what they were looking at , or really take too much notice as I was distracted. I think they may have said that the hub is nackered.

Its making a rubbing noise when you drive the cassette with the chain.

They said that I have done well to have the hub last 3 years. I Have a replacement set of ball bearings & a XT freehub can be obtained for about 40 quid iirc. Should I try this route first? Or could the surface that the ball bearings come into contact with on the hub be too worn?

Make sure the freehub is compatible - XTR hubs can be a bit odd.

The cones are replaceable. Shimano have tech manuals with part numbers and compatibility.

its 135 quid for a rear hub & then there is the cost of re building the wheel, as this would be required too wouldnt it?

WOuldnt it make more sense to buy a superstar wheel or maybe a xt rear wheel?

IF you need a new hub then yes a new wheel is more economically viable but as has been said the basic bearings and freehub should be cheaper and the hub itself is a good unit. Unless the rest of your wheel is wobbly you shouldn't need t replace it.

OK i have stripped the hub as far as I can. I cannot remove the freehub as i dont have a 14mm allen key. But I can see, on the non drive side the ball bearings are all held in by a ball bearing holder if that makes sense. On the drive side this is split & the ball bearings are loose & fell out. Can I get another one of these? If not, the ball bearings will be loose & I dont think will remain in place

Are you serious?

If you're going to service something, look at the manual and make sure you have the tools and replacement/spare parts.

Not seen a Shimano hub with caged balls before, all were loose and no they don't fall out.

go to techdocs.shimano.com and get the manual and stripdown list for the hub.

I did read the manual & I Have replacement ball bearings. ANd Allen keys, but a 14mm one is hardly an every day item.

THank you! I went & checked & on one side there is a ball retainer & on the freehub side there is not. I assumed that it would be the same on both sides.

How do you know if the ball bearings need replacing? ANd how do you know if the hub is worn?

Put some pics up let's have a look.

The cones keep the balls in place. You are probably seeing the dust cap.
