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)

Small frame - possible to fix?

I've got an old roadbike here, which is actually of kid's size (I'm quite tiny ). Do you think it's possible to make it a fixed gear? The bottom bracket is quite low...



It's a 46 cm frame with 26er wheels (sorry for the European measurements, don't know the US equivalents).

Currently I am using it on my Minoura rim drive trainer, but I'd like to make a bike for commuting out of it in spring. But since it's so small, I am not sure if making a fixie out of it would be the best idea. Maybe just a singlespeed with freewheel?

you could do a fixed gear just fine, but i would suggest shorter cranks if you decide to

Keep it geared? I don't know. I have so many geared bikes!
SSP with a free wheel would be an option, but I'd prefer the fixed version. Unfortunately the crank's already very short... and when it get's too short it woudn't be so nice to ride, I suppose.

Lose all the geared things, New back wheel, remove brakes as wished.
There you go, fixed gear.

Bikes: 2001 Bianchi Eros, 1976 Orbea conversion

I did a conversion from a pre-converted Centurion single speed myself, its really pretty easy. So long as your dropouts are long, you'll be fine. Although I'm running a 53cm-ish frame and 165mm cranks.. its pretty cramped. I want to get a bigger track specific frame sometime soon.

well if the chainline isn't straight.. new bb and crank to fit does the trick.

he wants a fixed gear let him have it.

It should work fine.

You can get very short BMX cranks if you're worried about clearance.

they said they're quite tiny so I would assume that it fits them...

Of course it fits. I am a girl, 1,57m (must be about 5'0) and I own this bike for quite a while now. First it was my bike to get to work with, now it's on the Minoura trainer.

I already have a "bike that was meant to be fixed": a custom made white track frame, which is a bit bigger than the violet bike, but fit's, too (just to make it clear again). Nevertheless, since it's a trackbike frame the bottom bracket is not that low.

And this was my own concern. I've seen lots and lots of fixed road bikes already. As long as the drop out is a horizontal one this really isn't a big problem.

Ya, I'd keep it the way it is. It looks like it's setup nice.
Definitely keep the way it is if it's your only geared bike.
