hmmmm.... everything seems solid and tight so i'll ring the bike shop tomorrow, see what they can come up with.
thanks
You know, the MOST bottom bracket is supposed to be super-stiff; so, frame flex (even if you are using the "adapter" to allow a normal BB) should be negligible ...
I've looked at the frame that I have which has the worst-combination of components -- a mismatched 8-speed front derailleur (i.e., wider cage, so it has to move a little further over to shift the chain in both directions) with a 9-speed chain on a 9-speed drivetrain (FSA ROAD crank) ...
When the chain is on the outer ring AND I am looking down the outer plate from above, the outer plate is flush with the "safety" pin on the ring which on the particular chainring extends about halfway to the crank arm's back side. There must be ~5mm (just eyeballing it) between the outer plate and the backside of the driveside crankarm when the front derailleur is at its maximum outer position.
This raises two questions about your bike's configuration:
- what chain are you using?
- what front derailleur are you using?
Is it possible that you are using a
10-speed Shimano chain in anything other than a 10-speed Shimano drivetrain?
OR, is it possible that if the drivetrain is a 10-speed Shimano that you are using the
wrong front derailleur -- a 6500 instead of a 6600, for example?
Of course, there are OTHER wrong combinations you could be using!
A 10-speed Shimano chain with a 10-speed Campagnolo drivetrain should also be avoided!
