Congrads,

I personally own a 900 for over five years now and use on track & street.
The only failing item are the bearings ( I ride the disk allot). which Zip will be most happy to sell
you.
This past season, I installed a road axle and a six speed freewheel for the Boonsboro Time Trial.
This design, not being lenticular ( curved ) makes the most awesome sound!!!! Great buy even if it does
weigh more than current units. As far as the cost of tubies well, once you ride them you will appreciate
them. They ( tubies) heat up quicker, which makes them very sticky on whatever surface you ride.
Also, the rubber compound is by far ( even the cheap ones ) better than any clincher.
