So, I should put on a warm-up gear (let's say 46x16), push the wheel to the end of the track ends, then shorten the chain accordingly? I think this will mean taking out 2 or 3 links. Does that sound right? If I understand this correctly, I should be able to run many, but not all, gear combos on this chain (like a 49x15). To run something bigger (like 50x14), I will need a longer chain.
