Description
Princeton Blur 633 V4 – a light, fast rear disc for time trials
The Princeton Blur 633 V4 is a full carbon rear disc wheel for time trials and triathlon. It weighs just 950 g, so it feels lively for a disc wheel.
Also, Princeton widened the rim from 19 mm to 23 mm inside for this version. That suits modern 28 mm tyres, which are faster and more comfortable. Plus, it rolls on Tactic ceramic bearings, so very little speed is lost to friction.

- 23 mm internal width, up from 19 mm
- Clincher, tubeless-ready tyre bed
- Tactic ceramic bearings
- 950 g wheel weight
