Grease rear wheel bearings or replace?

Unknown Soldier

Any advice is much appreciated!

I have found my 2011/12 cBoardman Hybrid pro acting strangely this last few weeks. To the point that I realised that I had to change the chain. But this morning it felt like I was towing another cyclist It's been a bit like that for a few weeks.

I keep the chain and cogs very clean, so it's not that.
The disc brakes rub every now and then but it's quite audible and very intermittent.

There is a noise coming from somewhere. It's not the BB30 as that was done a few months ago.

I *think* it might be the "wheel bearings". I took the rear wheel off this evening and when I removed the quick release, the yoke in the middle of the cassette (axle?) does have slight movement of a mill or two either way.

Would I be wasting my time taking it all apart to grease the bearings? Do I need to replace?

If I do have to replace, what with?

Bike spec...

Cassette: Shimano CS5700
Chain: KMC X10
Cranks: FSA Energy Compact BB30 50x34T
Bottom Bracket: FSA BB30
Shifters: SRAM Double Tap 10 speed
Rear Derailleur: SRAM Rival
Front Derailleur: SRAM Rival Microshift
Hubs: Formula Disc
Rims: Ritchey Pro Disc


[edit] I've done 2,707 on it so far this year and no greasing of bearings

Thanks in advance.

I have exactly the same bike and have already come up against exactly the same problem. That mil or two of movement in the axle will translate to a much larger amount of play at the wheel rim. Refit your wheel and see how much lateral play there is in the wheel. Look at the movement relative to the chain stays, as this makes it easier to see (or measure) how bad it is. Play of more than a couple of mil can be felt while cornering and is a bit disconcerting.

I removed the axle and bearings, cleaned, re-greased and reassembled. It's been OK since, though a couple of re-adjustments were necessary to keep it tight. Get some cone spanners if you don't already have some. You'll also need a cassette removal tool and chain whip.

The cones were slightly pitted and there was some evidence of scoring on the bearing surfaces in the hub, so I consider this wheel to be living on borrowed time. That said, it's been a few months since I've had to touch it, so I think it was well worth doing.

Good luck!

Did the noise start immediately after you replaced the chain? If so, check in case you made the same mistake that I made one of the first times I replaced a chain. If you look at the image below, at 9 o'clock on the bottom jockey wheel there is a guard. I had accidentally threaded the chain outside this rather than inside . Queue very difficult and noisy pedaling.

Also, does it only happen when pedaling or when freewheeling too?

OK so...

One side of the hub/bearings is in perfect condition. The other side....not so much.

I have replaced the bearings but the housing is badly scored. It's a b1tch getting the tightening of the cones correct :mad:

I suppose I will need a new rear wheel but would it be just as cheap/handy to have someone rebuild the wheel with a new hub?

Can anyone recommend someone in Dublin who could do this? And rough idea of the cost?

With cost of rebuild and new hub you'd get new wheel as cheap?

Email rose and ask them if wheels are disc or rim brake

Cheers (to all replies) I emailed them and the set they linked me to was quite expensive. 170 stg I couldn't find the rear alone.

I bit the bullet and bought a set of Shimano RX05's that are used on the latest 2014 boardman hybrid pro.

I also had to by a "Center Lock Adapter for 6-hole Brake Disc" as the Shimano system was different.

If anyone finds themselves in the same position...

The difference between a Shimano SM-RTAD05 Center Lock Adapter for 6-hole Brake Disc and a Shimano SM-RTAD10 Center Lock Adapter for 6-hole Brake Disc is that the [URL="file:///C:/Users/daithi7/Downloads/EV-SM-RTAD05-3636.pdf"]AD05[/URL] uses 6 screws to attach and the AD10 has them built in and locks using a cassette tool.



Honest to God, I don't understand why they make this all so complicated
I nearly had a nosebleed trying to figure all this out.

out of interest - are ceramic bearings much good day-to-day ?

Hey OP, glad to hear you were able to find something suitable.

I trimmed a bit more play out of my rear wheel bearings yesterday, so I'm keen to have a replacement on standby at this stage.

Can you let us know how these wheels work out for you? Hopefully they'll drop straight in without any spacing issues.

Waste of money if you ask me .
