I recently got an old 10 speed raleigh grand prix that was converted to a single-speed. What would I need to make it a fixed gear machine? And what would be the recommended sizing for road surfaces?

Thanks

HUH? Single-Speed = Fixed Gear.

Is this a test?

it depends on what type of wheel is on the back.

best way would be to get a wheel with a track hub, and put on a nice cog. (that is if you dont already have a rear wheel with a track hub.

check out the gear inch calculator on Sheldon browns site and find a combo in the 70/75 gear inch range.

single-speeds are not necessarily fixed gear.

fixed gear is, however, a single speed.

please google this before you make a bunch of people cry really really hard

HUH? Single-Speed = Fixed Gear.

All fixed gears are single-speed, but not all single-speeds are fixed gears. (The first part is not even necessarily true--there have been multi-speed fixed gears.)

OP, a single-speed could have been converted by simply removing the derailleur and putting the chain on a single cog in back. My point is that it's hard to tell you how to get somewhere without knowing where you're at. The proper route is to get a track or fixed/free flip-flop hub/wheel, but maybe you already have one.
