I'm considering shortening the chain on my MKIII Expert. The main question I have is wether it is possible to safely shorten the chain to a point where it cannot shift to the big ring/big ring combo. The big ring to big ring combo causes the chain to rub the frame, so it really is useless. Shortening the chain should allow the derailer (spelled like that on purpose) to sit better in the more used gears right? Would their be a potential for damage (like the drivetrain jaming, etc.) with the chain like that?
Also, I'm considering just removing the big ring, because I don't remember ever using one on a trail ride. My last bike was also used on road but this one will be strictly for trail use.
One other thing, when pedaling backwards the chain drops down, something is restricting it from moving quickly enough to keep up with the rest of the chain. Any idea why that might be? The chain does seem to be sticky to the touch (chain lube?) could that be it? is chain lube supposed to be sticky?
Pictures:
chain hitting frame in the big/big combo.
chain too long?
Thanks.
