Re: Shifter Kit from www.sickbikeparts.com
The wobble is in the freewheel itself, but I think it's pretty normal and tolerable. It's just about 1 to 2 mm. Maybe the chain tension is just too tight...I did retightened all the nuts and bolts on the chainrings, also the bottom bracket and cranks. Thanks.
Regardless if it's left or wrong, the opposite is always right.
