I've got a set of Mavic Cosmics on my bike and today I heard a ping and when I checked the aluminium hub attachment for a couple of spokes has broken on the rear wheel. Is it worth getting a new hub and rebuilding or is that likely to be as expensive as replacing the wheel (about £400ish I think)

If the rest of the wheel is in good condition it's surely worth getting it built up as it's a £500 wheel.

Warranty job?

What's the age of the wheel - Mavic only keep spares for wheels up to something like 3 years old, but I expect you can get it built onto something, even if you have to change the spokes.

Cheapest way is to loosely build the wheel yourself and then pay someone to true and tension it for you.

it would be worth rebuilding as it’ll just be the spokes that have been over tensioned and that’s why they’ve snapped, they reached their elasticity limit. however by virtue of you asking the question, i’m assuming you can’t do this yourself, so a rebuild with 11 speed hub and new spokes is the order of the day. New rim too unless yours is very good condition. you can use your sub 11 speed (if that’s the case) cassette but youlll be future proof by having an 11 speed hub already.

105 hubs are bombproof but heavy, I’ve got a novatec lightweight 11 speed on my rear and it’s great for about the same money

ah, just seen this, sorry jim.

Im guessing a it’s a 28 or less spokes? great for racing, shit for our potholed roads! 

if you are already 11 speed (probably) then replace the spokes and true up, accept the fact carbon rims will snap the odd spoke, they don’t have the give that alloy has. perhaps get a cord spoke for your tool bag if you carry one? It’ll get you home if needed. Not needed it yet but i have one of these:

It’s not the spokes that broke it was the hub itself, it’s about 5yo so out of warranty. It’s t a 24 spoke wheel and all the latest models seem to be 20 spoke. Rim and spokes are ok

It might be worth contacting Malcom at http://www.thecycleclinic.co.uk

He appears to know a fair amount about wheel building and the availability of parts.

Mavic will cover the rebuild under warranty, even though its over the warranty period. Great customer service ethos from Mavic.

Sounds like you’re going to end up with Trigger’s broom...

:-; in fairness the wheel was in very good condition as I’d always kept it clean and used the swissstop yellow brake pads so the rims are in almost pristine condition

Eh? Are you not describing a complete new wheel there?

I misread the OP and answered as though it was spoke breakage, turns out it the hub that’s blown
