Track bikes - what gear sizes?

[montage]

I imagine they run on 100" or something...

...also is it possible to make a track bike which can easily be put onto the road (guess this means a tyre change and whacking on a front brake).

I run a bike which, with a tyre change and a front brake (It has a flip-off lever) is at home on manchester velodrome. I'm running 48*14 which is quite suitable for the track and my flatish 13 mile commute across manchester. I make sure it's clean before I go down the velodrome though.

Manchester are pernickety about BB height and crank length though, are they not?

 

[dan_bo]

yep. 11" bb and 165mm cranks. It's not like they have spot checks but if you're involved in an accirent then you could be held liable.

Depends what track it is. Some are easier then others. The one near me, i could just turn my back wheel around(use the gear i use when i do a TT) and go on it. I dont know if i could do the track leage like this because of my front brake, but it wouldnt take long for me to take that off.
But due to the track near me not being fast, my TT gear would be fine on there, bit spinny(bit too spinny on TTs aswell, even though there are a few uphill sections)
Arent some tracks abit funny if your fork is drilled aswell?

Anybody know if Manchester is picky about the Miche sprocket system? Might only be a rumour I've heard as it still uses a lockring.

I'm pretty sure Manchester is also selective about tyres - and they need to be scrubbed down before first use anyway.
