Track bike - frame size question(10 posts)

Track bike - frame size questionAlanE
Apr 23, 2002 3:51 AM
I'm looking into buying a track/fixed gear bike, and I have a quick question on sizing. Do you ride the same size track bike as your road bike? Do you try to setup your position the same as on your road bike? What about things like crank arm length, handlebar width, etc.

My 2 road bikes are sizes 56 & 58. I'm about 5'11". I'm considering buying something used to get started, and may be buying a bike from someone on ebay without being able to test ride it first.

Thanks for your help.
Racers will use something 1-2cm smaller.MB1

For road use don't bother.

On the track, you are always in the drops. Most folks today are buying road bikes sized to make riding in the drops for extended periods uncomfortable. If this is true of your road bike, sizing down for the track is not a good idea.

Track bikes have a higher BB. This will affect your position as well. It may be smart to sit on this bike before you buy it.

Interesting point - Quill stems are still dominant at the track because of their height flexibility.

since you have 2 road bikes already, why not simply convert one to fixed? it'll cost you less than 100 bucks, youre guaranteed perfect fit, and you can convert it back in under an hour whenever you want.

unless, of course, youre actually buying it to ride on a track.

I have 2 road bikes set up exactly the same at 56cm. Seat, frame, stem, bar width, crank arms and gruppo are both identical. I have a track bike that used to be a road bike that I had converted in the shop. It has had all of what makes it a road bike removed or patched up. The only thing that gives it away is that it has holes for water bottle cages.

There are some subtle differences in the way that I set up the track bike compared to the road bikes:
stem height, bullhorn bars and a fixed rear. The frame was a bit smaller (55cm) in size than my others. It seems to make a difference in a good way. I get more leverage to stop when I am slowing down.

I dont know if this helps any.

dropouts... not quite track. kinda reverse-horizontal.
i'm intrigued...whats the story with those?

Aegis road frame that I wrecked in a crash. I sent it back and had them convert it to a track frame.

They have the removable dropouts that they have 2 types for road and track. Messengers are always commenting on the "beefy" look.

It is one of the funnest bikes I have ever ridden. It is road bike geometry with track bike parts. The Carbon Fibre soaks up all the road shock when I ride it in the city or long rides.

Amazing training tool.

my main ride is my old fixxie beater- way more fun the my carbon 2100, though the carbon (which i rarely ride) is muuuuch more comfortable.

I would have converted the carbon to fixed years ago, if not for the vertical drops (my setup would yield me only two possibilities - 70 inches or 82).

Out of curiosity, did you get a price on replacing the dropouts, or was it included as part of a complete repair-job?
Aegis actually makes both dropoutsonespeed

They dont make a lot of them though. I have been waiting to unload another Aegis track frame on ebay (58cm) but have been waiting for them to make a new batch since I took the current ones off the (58cm)other frame.

The current track frame is 55cm.
