DRivetrain is making a funny noise when under load, sort of a rhythmic creaking more so when seated than standing. I replaced the chain, checked BB for play - it is a Truvativ GXP Xpipe with a Bonty Race Lite triple - no play in the cranks either. Mech is Ultegra. Wheels are EAston EA90s and newish so not the hubs. Strangely there is also a tinkling sound like something hitting the spokes, yet there is nothing in contact with them. The bike is just over a year old and has 1900 miles on the clock. The only thing I have not checked is seatpost clamp tightness.
Two questions:
1. Any idea what it might be? If likely to be crankset I can change that for Ultegra as chainreaction have a stunning offer;
2. Anyone had experience of Ev*ns mechanics to take a look at it? I know some have said they'd rather empty a bag of spanners over their bike than go there but we have a branch in Canary Wharf and I cannot get to Butlers or Dauphin before the weekend. Plus I bought the bike from Ev*ns despite it now being just out of warranty.
Thanks for any advice.
