Hi all,

Thanks for the responses. Unless I'm missing something it's easier to go 20mph on a geared bike (both acceleration at top speed) than it is on my fixie when I have to petal at a very high RPM. Having a geared bike also allows me to either go faster or at least not have to petal while going downhill.

Back to my actual conversion though, it looks like my rear drops are right around 120mm, this bike used to be a road bike that got converted at some point to a single speed. So what is everyone's opinion between adding gears to the crank versus the rear, obviously I can have more gears in the back. Which should give me a larger spread between the bottom and top ratios, which is easier to convert, which has less maintenance, which adds less weight, which is better for balance?
