My commuter road bike (Pinnacle Arkose 3 - actually a disc-braked cross bike, fitted with mudguards) has an annoying and loud creak, associated with each turn of the pedals - there is a creak each time a pedal passes the 2-3 o'clock position, on either side.
It sounds like a bottom bracket creak, but I have replaced the bottom bracket and adequately tightened it, yet the creak continues.
If I unclip one foot and pedal one-legged the creak stops - this works for either foot. If I pedal very lightly at a very high cadence (e.g. 120 RPM), the creak stops.
If I pedal hard or sprint out of the saddle, the creak is louder.
If I stop and tighten the rear wheel quick release (traditional QR, rather than through-axle), the creak stops, but inevitably returns, often within a few miles.
So far I have tried/checked:
- swapping in the QR skewer from my turbo trainer and this makes no difference - the creak only goes away temporarily
- checking the chain for wear - currently showing as 0.5% worn
- checking the rear wheel is properly seated in the dropouts
- tightening the bolts on the rear derailleur hanger, which the QR skewer tightens to
What else can I try to resolve this annoying creak? It's driving me crazy! I'm also concerned it could be a sign something is under fatigue or close to breaking.
