Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

New Single speed or Fixie project. Cannondale R500

I'm just starting to get into the bike world, and am unsure of many things.

I just Got a single speed bike, and was wondering what the limits are on it if any.

The bike has a cannondale R500 frame with a sugino crankset. it wa originally a geared bike from what i can tell, and has a locked derailer still on it. The rear drops seem wide, but it may just be the wheels, i'm not sure. there are spacers on it to line up the crank and the rear hub.

I was just wondering if i could turn this into a fixie, or if i should just leave it as a singlespeed toy

You can turn just about anything into a fixie.

You'll need a track rear wheel, cog and lockring, and you may need a new crank / bottom bracket to make sure your chainline is straight. It all depends on what you want and what your budget is.

Sure "anything" is possible, but some frames with vertical drop-outs are a real pain to work with--- and therein lie the limits. A track wheel will not be particularly helpful... and most R500s were triples, so you probably have an unusable BB (unless it was swapped out with the crank).

That's what I think too. The simplest and cheapest path is to start with a frame that has horizontal dropouts and a rear wheel that matches your dropout width.

Doesn't the R500 have either vertical drops or very little to no room to slide the axle (if somewhat horizontal)?

i borrowed a friend's Cannondale R500 for a 70mi ride once. I'm pretty sure that it has vertical drops too. But it might differ by year? Anywho, I remembered it rode nicely as a geared bike.

well like i said, the rear drops seemed really wide so i'm not sure. And yeah, im pretty sure that all r500's have vertical drops.
