Noise from Mavic Aksium

essex-commuter

Had my new Ribble bike a couple of weeks now, clocked up just over 400 miles.

I’ve got an annoying click coming from the rear Mavic Aksium.

It happens once every revolution.
It happens whether I’m pedalling or not (so not bottom bracket).
Happens if I’m standing or seated (so not saddle/seat post).
If I lean forward and take weight off the back wheel it goes away.
If I spin the wheel without any weight on it, it’s quiet.
The 11 speed Shimano cassette is tight.

Ribble have said I can send it back and they will investigate, but before I go to the hassle of that does anyone have any ideas?

Man Of Lard

The pawls in the freehub (which is made of camembert on a Mavic Aksium) are failing to disengage cleanly - short term solution is to remove the freehub, clean & relubricate the pawls and reassemble.

Longer term solution is to decant them into the recycling and buy wheels with non-cheese freehub.

Doesn't sound like that to me, it sounds more like the cottage cheese balls that masquerade as wheel bearings are doing their normal magic trick of try to turn into 20 sided die.

Have you got discs?
I just solved my annoying click by tweaking the brake calliper position...

No discs.

Wheel went back to Ribble, they stripped it, couldn't find anything wrong. They test rode it, said nothing wrong. They sent it back to me, now it's perfect.

I have no answer.

You have a quiet wheel though...

If it comes back:

Is the valve stem rattling in the hole in the rim? Easy to stick a bit of elec tape round it to see if it silences it.

Spot of oil on each spoke head in the hub and at any point where they cross?

I do have a quiet wheel and it's bliss. I'm OCD with creaks and clicks on the bikes. Checked the valve stem, that was OK. Didn't oil any spokes though. I told Ribble I was 90% sure the noise was from the spoke/rim or spoke/hub interface, after 30 years of riding you kinda get to know noises.

Me too. I love the sound of a quiet bike. I'm pathological in pursuit of minor creaks, clicks and rattles that other riders appear happy to tolerate.

Just seen this post and I've had EXACTLY the same issue driving me nuts for the last 18 months!
Unfortunately I bought the wheel from Acycles and even before they went into liquidation they were not helping to solve the problem.
Stripping down the hub and rebuilding is beyond me. Can anyone give any tips as to how to resolve this issues please?
Thanks

If you've had an Aksium for 18 months I'm surprised the freehub still works at all. As noted above, the from age-like consistency of the pawls and bearings in there would generally see the pawls start failing to release after six months (not an issue only with cheap Mavic wheels, - Google 'Mavic squeal of death' for info) and the bearings turn into tiny little replicas of 20p pieces after a year.

I'd suggest replacing the freehub entirely with something that isn't sh1te, but that's probably not what you want to hear...

I'd never ride Aksiums - they're censored quality and disintegrate at the sight of mud and water, so useless on a winter bike, and too slow and cumbersome to use on a decent bike. My advice would be to replace with something like a Fulcrum 5 if it's a commuter/winter bike or Ksyriums if it's a 'good' bike

Thanks for your advice. Mine were actually Mavic Allroads but exactly the same symptoms! I got them for my £800 Specialized hybrid that I use for commuting and trails with the kids, so I needed a wheel that took disc brakes and 35mm tyres. The clicking noise drove me nuts so I reverted back to an old wheel after a few weeks - which is now absolutely dead, hence looking into it again.

Not sure whether to try and get it fixed by someone who knows what the problem is or accept it was £150 down the toilet and get something else?

Depends on your budget. If it's just the pawls you can get them re-greased, if it's the bearings, get them replaced. Problem is, it will inevitably happen again, You could just replace the whole freehub, but it's probably not going to be much more expensive to get a new rear wheel instead - one that isn't going to disintegrate
