Prototype Disc Brake Cannondale Super-X Cyclocross Bike & Zipp 135 Firecrest Cross Wheels!
Cannondale-CyclocrossWorld.com director Stu Thorne leaked this image of a prototype disc brake equipped Cannondale Super-X ‘cross bike that team rider Tim Johnson will be racing this weekend in Boulder, CO.
There aren’t a lot of details yet, but the basics are:
- 135mm rear spacing
- Direct mount disc brake tabs set for 140mm rotors front and rear
- All-new disc-specific fork
BikeRadar’s reporting the bike definitely has a reinforced rear triangle and that the post mounts for the rear brake are pretty much embedded right in the frame. The fork looks to be a completely new offering made just for this bike with a claimed weight of 450g.
What’s just as interesting as the bike is the fact that it’s running what must be 135mm disc wheels from Zipp, which is not currently a catalog item. Zipp is owned by SRAM, which further supports the rumor that a certain major manufacturer will soon release a full-on road bike disc brake group. Our money’s on hydraulics since, you know, they already make mechanicals and that just wouldn’t be news, now would it?
UPDATE: The wheels are currently built on White Industries The One 24-hole hubs while Zipp develops it’s own hubs for this application. Their running on the Firecrest 303 tubular rims, but Zipp PR manager David Ripley says the wheels will be available in both clincher and tubular when they are official.
