I wanted to the C2 tubular hoops for my Cyclocross bike real bad. The Belgian/ardennes bed works awesome for 32c and I've watched guys case concrete stairs with them and they come out unscathed.
None of that is really useful for a track bike unless it's also your tarck bike. Also, for the 8-900 they want for them you could pay msrp to have a shop build you a bit lighter and a bit narrower for 19-23c.
Shrug.
