Note that this is not a geometry chart of your frame, but it contains all the important data of your fully equipped bike, to get your position right.
Saddle height, front/aft position, reach, handlebar height, etc.
HarrieH's classic track bike project
A track bike has the beauty of simplicity. No distraction of cables, bottle holders, pumps and other accessories. Just a frame, fork, drivetrain, steering components and something to sit on will do the job on a track.
Some parts I already have for decades, others I have to collect. It's fun to look for the right components, to get them, build up the bike and, of course, ride it on the velodrome.
Oh, besides track, lots of (off-)road stuff as well.
