Question Q on zipp 303 disc

[Dogstation]

Can anyone tell me why some zipp 303 discs have a rim brake track on and others don't? Are they an early model or might they have been converted? Thanks

I'm pretty sure the first disc brake 303s had a brake track, they were released in 2014, but they weren't just a conversion as the spoke count was increased at the front to 24 and they dropped the radial lacing. I think the 2015 disc wheels didn't have a brake track and from that point on this was the norm. As such, any rims from 2015 onwards with a brake track on disc hubs are likely converted.

Great info thanks
