I should know this, but...
I took an old front gear and crank off a very dead Raliegh three-speed. It's a bigger size (more teeth) than the one that's already on my Triumph. I live in an area that's mostly hill. Would I be better off to leave the Triumph as-is or put on the new unit? The cranks are about an inch longer too. Matter of fact, I've already got the left side crank changed, because I totalled the thread where the pedal attatches on the old one. The difference in length doesn't seem noticable at all, much to my surprise.
I know that smaller front gear=easier hills on an 18Spd, but does it still work that way on a single? Would the longer crank even things out? I haven't tried it yet or I wouldn't be asking, but I think the chain will just fit on the larger gear.
Geez, I feel stupid!
