I need to replace the bottom bracket on my 2011 specialized stumpjumper.
I’d like to get one ordered this evening, can anyone recommend which is best value?
It states PF30 on the side of the fitted one.
To many to choose from on the websites, alloy ceramic etc!
Cheers

Wheels Manufacturing PF Bottom Bracket costs £10 more than the Sram offering that the bike would have originally had fitted but is a much better quality and longer lasting piece of kit.

I’ve fitted a few of these for a friend. The SRAM one is shit. Forget it.
The Wheels Manufacturing one is better but doesn’t last that much longer. In its favour it uses an easily available and replaceable bearing that can be had for around £20 a pair.
I’d like to try a Praxis Works or a Rotor 24mm axle converter BB if he ever changes the cranks.

Pick one. Don’t bother with ceramic. Waste of money. 🙂

I think the Rotor one is the Press Fit 4630 for 30mm axles and the 4624 for (surprisingly…!) 24mm axles.
These are way better than press in converters if you want to switch to Shimano cranks.
