Zipp 06 Zipp Track Disc Axle Conversion Kit

When you’re ready to take the plunge and go for glory on the track, use this kit to convert any dimpled 900 road disc (from early 2005 to current models) to a track disc.To identify if your disc is compatible with this conversion, look for these things:• Dimpled disc surface.• Red or blue free hub body, NOT silver (see '04).• This does not work with the Super-9 -- only with a 900 or 840 dimpled disc with silver hub flanges.If your disc has a silver free hub body this conversion kit is NOT compatible; please see the ’04 track axle conversion kit. Conversion kits are no longer available for smooth-sided discs, sorry. The Super-9 disc has a thicker axle and a different axle conversion kit.
