I was hoping you could advise on a good track bike; looking at a Dolan Precursa, a Zannata Z92 and a Ridley Oval, but I guess you don't know any better than me.
I tried it a couple of months ago; went to 3 beginner sessions at the Apeldoorn indoor velodrome. Brilliant fun and I shall be doing more this winter, probably sprints and 750metre time trial ('masters' do 750m instead of 1k). That, seeing as my shoulders are now too knackered for rugby or discus. Trouble is, the hired bikes at velodromes usually have a weedy low gearing so you have to pedal like mad to keep up. Good for training, no good for racing.
Go and try it; absolutely great fun; you'll get used to the bike very quickly, but yes, you do need a slight loony streak to ride one. Actually the lack of freewheel or brakes is a safety thing; if you're all riding at 60kph or more and one person slows down suddenly then everyone will smash into him. Which provides a good laugh for spectators.
