Rear wheel recommendations

[Fraz101]

So the inner hub race has broken off my rear wheel of my commuter mtb

It’s 26” with QR with a 7 speed screw on freewheel.

Can anyone advise where best to get one.

Not looking for anything fancy,just a replacement QR wheel.

Any links are most appreciated!

How long did it last? Do you want a replacement, or something stronger?

Have you tried ebay?

It’s the original wheel.

Bike is about 12years old.

Just a replacement really.

worth noting that the rear hub will also have a particular width; IIRC yours being an MTB the rear hub will probably be 135mm wide.

The common pattern of events with wheels like the original one is that the axle breaks, a new axle is fitted and then the hub breaks. The last of these usually occurs because the cones that came with the new axle were used; the chances of these being the right shape are pretty small, and if they are wrong this does some very evil things to the bearings.

Because this kind of failure is so likely, I would recommend that (if you intend to ride the bike much) you buy a wheel with a cassette hub instead of one that accepts a screw-on freewheel. The rear hub will be far stronger.

Here’s what’s happened

As you can see the inner race has broken off the hub.

I replaced the bearings a few months ago but tbh they haven’t felt “smooth” when turned by hand for a while.

that is exactly the kind of damage that is often caused by using the wrong cones in the hub. It might have happened anyway, but 'wrong comes' will definitely cause it, IME.

It is the original cones and axle

I only replaced the ball bearings.

I managed to pick up a used wheel from my local recyc a bike this avo for £5.

So I’ll run that til it breaks!

Only difference is it’s not got QR on it but not the end of the world (I don’t want to strip the bearing and fit my qr skew

[Brucey]

note that QR axles and solid axles frequently have different threading on anyway, so you may have spared yourself a bit of aggro there.

I figured it wouldn’t be straight forward,a couple nuts either side isn’t difficult!

The wheel even had a decent 7speed shimano free wheel attached. Not bad for a fiver!

Driveside bearing cup broken out of pressed steel hubs? …..I have seen that most often when the driveside cone hasn't been properly locked off, and you find the cone some way down the axle.

[Brucey]

yup, that'll do it for sure.

IIRC there have been previous threads about this including

- a mysteriously destroyed 105 freehub and
- an aluminium hubshell that had been crushed lengthwise by the effects of precession.

not that I can find it now but IIRC I posted a photo of a blue hubshell that had suffered the latter fate.

However if the cones are the wrong shape (and it doesn't have to be much) this also causes the bearings to disintegrate.

A while ago I was speaking to an LBS owner and he mentioned that 'front hubs didn't seem to be very well made these days'. I asked him what he meant and he reported that he'd seen a lot of front hubs with bearings that were destroyed. Putting two and two together, I asked if he'd fitted different axles to many of the hubs that had then failed; turned out he had; every other bike he sold had a basket fitted and this was usually made possible via a new solid axle in place of the QR one originally specced. He had a small bucket full of unused front QR axles and the ones he'd been fitting instead (which had differen threading, so you couldn't swap the cones over) were different to that.
