Princeton Peak 4550 Evolution Disc Tubeless Ready road bike wheels – Tactic Racing TR01 hubs

If you’re looking for a pair of wheels to take your road bike to the next level, these Princeton Peak 4550 Evolution Disc wheels are exactly what you need. Acclaimed by professional riders in the world’s biggest races such as the Tour de France, these exceptional wheels promise improvements in aerodynamics and stiffness. Weighing just 1,275 grams, which is very light for a 45/50 mm profile height, this pair is manoeuvrable and responsive, allowing you to make a difference on climbs whilst remaining perfectly comfortable on descents.

Thanks to Sapim CX-Ray spokes, radially offset lacing and the special rim shape, these wheels also perform well on the flat, being aerodynamic and resistant to crosswinds. With increased width (21 mm internal, 28.2 mm max external), these Princeton Peak 4550 Evolution Disc wheels are optimised to accommodate 25–28 mm Tubeless Ready tyres. Finally, the ultra-light Tactic Racing TR01 hubs offer low friction thanks to ABEC 7 ceramic bearings.
