Dolan Pre Cursa / PreCursa / Track Champion

A track set up for 20 mile rides is a personal choice. Your question is a bit like asking us how many spacers you should use for the right handlebar height.
Whatever feels right.
Liking the look, and the price isnt the best start. Find someone who has a track champ, and go for a spin. Imagine 20 miles plus, and you'll have your answer......After your 20 miles, drop a few curbs, and i guarantee you'll know whether its a good choice.
Kind regards
A track champ owner - who only rides it on the track. :)

Just want to know generally if the geometry is friendly for longer rides. Not going to ride it on the track...
