Dolan Pre Cursa / PreCursa / Track Champion

The bike will be my commuter. The place where I work is some 15 km from my house and in the three years that I've had my current job, I have never got there by any other means than by bike, regardless of weather conditions. I've had lots of fun commuting on a steel conversion but since that died recently, I've been riding an alu track frame to work, which is perfectly comfortable.

Most of the time by far and away, I run 23mm tyres and I will continue to do so. However, I need the frame to be able to accept bigger tyres comes winter, like my old conversion did. An On One Machinato probably sits somewhere between the Pomp and the Pre Cursa, but doesn't seem to have the tyre clearance I occasionally require.

The bike will be fixed wheel with only a front brake. That makes the canti bosses on the Pompino completely irrelevant for me. I have carbon road forks and a carbon cx fork kicking about, which means I can either get a Pomp and use the cx fork, or a Pre Cursa with road fork and only swap forks when I need the tyre clearance of the cx fork. The handling might be compromised by the increased axle to crown, but in the 9 months a year when I don't need that clearance, I'll benefit from the lightness and stiffness that an alu frame offers (point Pre Cursa). Then again, in the past 3 years of commuting, I've been in a couple of crashes that might have destroyed an alu frame. Also, it should be as unattractive to thieves as possible (point Pompino).

So yeah, I'm just not sure?

Surely this is what you need?
