I recently went to Pedal Revolution (SF, CA) and had my spokes tightened. Now, the chain has fallen off the derailleur 3 times on my ZebraKenko. Do you think I need a replacement part? I don't think they even make parts for this bike anymore. I put it back underneath the little hook of the derailleur, which I have never seen on other road bikes and the chain doesn't fall off, BUT when I backpedal, it pops off.
well, i just backpedaled after i put the chain back on and did it slowly this time.....the derailleur is too far from the chain path....can i tighten this myself? the back wheel is as straight as it's going to get--i doubled checked this....****ing shop ****.
they also overcharged me when i got my wheel fixed....prolly knew if they ****ed it up i would be back for more.
