I just got done putting this bike together. Everything is great except for the rear derailluer when trying to shift onto the largest cog. Goes from this on the second to last:
to this when it shifts onto the last cog:
It binds up and makes a bunch of racket and the only way to release it is to shift back down while reverse pedaling.
Is the chain too short? It's brand new and I sized it by wrapping it over the two largest cogs (the front only has the two smaller because of the bash guard taking up the space of the third (I just realized that might be the problem, duh!) and then adding 2 rivets (or one inch) per the instructions.
Any help here?
