Hi everyone, i need some advise if thats ok, i have loud clicking coming from the bottom bracket on my rockhopper comp 29er 2014, first i changed the pedals to some nukeproof ones but clicking is still there. It happens when i stand up and pedal and also under light load when sitting down. I think its the bottom bracket. I want to get them replaced but my local bike shop only supplys a cheap replacement so i have decided to buy my own which they said they will fit. I need to make sure i get the right bottom bracket as i dont want to buy the wrong thing.

Specialized Rockhopper Comp 29er 2014 Mountain Bike | Evans Cycles this is the bike i have with the specs the bottom bracket is GXP BB for 2pc., 73mm shell

I dont want to pay out a fortune but at the same time i dont want the cheapest around.
i have been having a look on http://www.chainreactioncycles.com/bottom-brackets/mtb-road-bottom-brackets?f=2258 but not sure which one i should get. The bike is mainly used to commute to and from work but occasionally i do like to hit the trails.

Any help would be greatfully received


Many Thanks

Well the spec sheet says GXP which is SRAM. However, I have learned to look for slight proprietary engineering changes from Specialized.

GXP is the SRAM external bearing BB design. 73mm means you don't use the spacers.

Have you checked if the bottom bracket is installed to the correct torque with anti-seize or teflon tape used on the threads. A dry or under/over torqued bottom bracket can often be the source of clicking and creaking.

+1 My Stump Jumper Comp did same thing shop stopped it but its back.
I'm going to do what Bike Whisper said above it will stop the noise.

Follow Bike Whisperer's advice and ask the shop where you bought the bike to remove the bottom bracket and reinstall with anti-seize (it's applied with a brush to the shell threads).

Thank You all for your replys, i will try what you said and see if that helps before paying out for a new bottom bracket.

Make sure the pedals are tight. I just put a set of pedals on my bike and after a few rides I was getting a clicking every rotation when pedalling. Ended up my left pedal worked loose. Tightened it down and the clicking stopped.
