it's steep. shift to 23. click, click, click. stop and turn the wheel but there's no click. mount and ride. click, click. downshift to 19. no more click.
would anyone know what's going on here?
Wheel flex?TJeanloz

My guess is that while you ride, and the wheel is under the load of your wieght and the power of the pedal stroke (especially uphill), the wheel is flexing itself into the derailuer. You can't replicate it in the stand because the wheel is spinning without the load - so there's no flex. There are three possible causes (in order of severity): 1) misadjusted derailluer; 2) bent hanger; 3) bent derailluer.

maybe the rear wheel under tension or deformation (with you in the saddle) brings the spokes to close to the der.
is that a standard wheelset?
perhaps you can check spoke tension and the centering of the rim.
thanks: i'll check wheel, derr. and hanger. nmcolker
