I have a geared XL Sir and when pedaling uphill or pushing hard (but especially when pedalling uphill) the bike makes a creaking sound as if the bike is strugling (I'm the one that should be strugling). Would anyone have any idea what could be causing this? At first I though it might have been the gearing ratio I using at the time but II don't think that's it now. It's not frame flex is it?

thanking in advancei

Could be many things, but the first thing I'd check is the EBB.

dude
its a mountain bike
it makes noise
if it doesn't make noise you are not riding it hard enough
tighten your bolts and ride

Hard To Say

Creaks can be tough to diagnose without actually riding the bike or hearing it first hand. Can you determine the general area where the noise is coming from? This will help to steer you in the right direction.

Does it occur when seated or standing? Seatposts and saddles are notorious. Your EBB might need a healthy dollop of grease too.

Sounds like a rainy day project. Get some good grease at the ready (Phil Wood is delish), disassemble everything, apply copious amounts of grease where appropriate and torque back to spec.

Ride.

There is no good reason for your bike to creak.

Don't forget the pedals. I had a squeak under the same conditions and went through the usual suspects -- bb, seat post/seat, headset, chain wheel. It turned out some dirt got past the dust shield on my Time pedals. A litttle grease and it was good. Good luck.
