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?

narrow spacing

I just acquired an old Royce Union single speed coaster brake bike, and i plan to replace the wheels and swap to fixed gear. Here's the issue though.
Front is 90mm, and rear is 105mm. So far every wheel I've seen is 100 front and 110 at narrowest, usually 120 rear.

Am I missing something? Where should I look? I am DEFINATLY looking for budget wheels.

I kinda need quick release front, but understand that bolt on rear is generally considered safer.

Any suggestions?

You can cold set the dropouts pretty easily.

If you want to drop some cash on tools, park makes a spreader bar, rear drop out alignment checker (long curved aluminum bar basically) and these two things that screw onto your drops to check that they're parallel.

If not, cough up some cash and have a shop do it.

Or go to your local bike co-op.

Or borrow them from friends?


You also may be able to respace the rear if there are spacers on your axle. I think most generic track axles can be, someone may correct me though.

My front formula hub respaced to 90mm real nicely, and something like 127 in the rear with a bit of finesse. All I have on the axle in the front now are the gripnuts. The axle is a little long, though. And I don't know what kind of wheels you're looking for.

cheapie ebay, bicyclewheels.com, bikeisland... any of their wheel sets. machined for brakes is a plus. I'm shooting for 700c, cause I think they'll fit, but it currently has 26in wheels with large tires. I tried my girls 27in (can't remember tire size, but not tiny) and it just barely rubbed the fork... i think a small tire 700c should work.

Cold set, does that only require the park tools? Basically you just stretch them wider, or is there a "procedure" to it? Most lbs offer it? What kinda price would I be looking at? One place I e-mailed replied back that their wheels might work, but I should cold set the frame.

I didn't know if I could run the front with no nuts.... assuming they are like my current road wheels on other bikes, there are two peices (round, but flat on opposite sides) that thread on to center up the hub, then two nuts that work as lock nuts against them. Is it alright to run without those lock nuts?

As for rear... I'm kinda just hoping that the same (running no spacers, and possibly no locknuts) can be done with a wheel that is normally 110 or so.

I really thought finding a single speed was gonna make the fixie thing easier... but it's making it a pain. Maybe old Royce Unions aren't the norm.

EDIT: cross linking for people who may be looking this up later. Has links to sheldon brown's site on cold setting using a 2x4...
