Crank Noise

[Downward]

Evening.
When I put a lot of weight on the pedals (Eg Standing up or really pedalling forcefully) I get a grinding/knocking from the Crank.

Bike is 8 months old and bout 900 miles on it.

Should I be worried and off to the LBS for them to have a look ??

take it to the LBS

sounds like its something to do with the BB

Yeah I very rarely get out the saddle so only noticed today whilst giving the bits below an airing !

It's pretty new. Could be the BB (what type is it?), pedals, chain rub or even a cracked frame. BB is the likeliest.

P.S. There's quite a lot of crank noise in P&L!

Take it back if not sure. TBH, loose BB, busted BB, loose pedals, loose chain rings....then could be anything else as noise travels on a bike.

Boo It's in the LBS now, Just as I have to drive in today too there is the mother of all traffic jams. Ironically when Cycling the route the Traffic has only ever been that bad once in 10 months.

Eeek maybe upto 2 weeks without it too. May need to buy some petrol for the car,

Something was loose in mine - Simple case of tightening it up.
