Hey I'm fairly new to all this stuff and just pretty much want to know what's going to be easier to ride with..

I'm currently riding a 48x16 fixed and struggle to climb big hills and it's a little tough to gain some speed quick off the traffic lights and I can only skid using the balls to headtube technique, I want to be able to spin more so I can climb more hills and skid easier/quicker etc etc..

I've been reading Sheldon Brown stuff but can't get my head around stuff without asking questions.

I love the speed I gain while using 48x16 and I don't want to lose a whole lot of speed but just so it's easier for what I've said just above ^ - What would I be better off changing, the chainring or the cog or doesn't it matter at all?

Even if somebody could PM me and is willing to help me out it's much appreciated! Cheers.
