Princeton Blur 633 V5 Rear

The Princeton CarbonWorks Blur 633 V5 rear wheel is a performance-oriented, uncompromising and ultra-stiff premium carbon lenticular wheel (full disc wheel) from Princeton CarbonWorks' absolute top class. This full disc rear wheel has been developed specifically for pure, relentless speed in time trials and triathlon at the very highest level. Where the competition often opts for heavier constructions, the legendary Blur line – known from the WorldTour successes and world titles of Filippo Ganna and INEOS Grenadiers – combines extremely low weight with unrivalled torsional stiffness.

The construction is based on a monocoque carbon structure handmade entirely in the USA, in which the outer shell is fully load-bearing, without the need for heavy internal reinforcements. What makes this wheel unique is the integration of a completely holeless tyre bed. Because there are no spoke holes in the rim bed, the wheel is structurally much stronger, lighter and immediately 100% airtight for tubeless use without rim tape. The heart of this V5 generation is built around the ultra-high-end Tactic Racing TR01 v2 hub internals. This ultra-modern drive system is equipped with premium ceramic bearings, ensuring minimal mechanical resistance when every fraction of a watt counts.

Features

• Weight: Just 910 grams, an impressive weight saving of no less than 125 grams compared to the previous V4 version. This makes it one of the absolute lightweights among full disc race wheels on the market.
• Construction: Fully hand-built full monocoque carbon construction. The holeless rim bed increases the structural integrity of the carbon fibres and delivers incredibly direct acceleration during power peaks.
• Rim profile: Designed with a modern internal rim width of 23 mm. This ensures that wider road tyres form an aerodynamically perfect, smooth transition with the rim edge and are supported more stably in fast corners.
• Rim bed (Hooked): Equipped with a traditional hooked rim edge. This keeps this full disc wheel universally compatible with both the very latest tubeless road tyres and traditional folding tyres with an inner tube.
• Tyre compatibility: Specifically designed for modern road and time trial tyres. Optimally tuned for tyre widths of 25 mm to 28 mm in terms of aerodynamics and rolling resistance, but safe to use across a broader range.
• Hub & Drive: Fitted with the exclusive Tactic Racing TR01 v2 hub internals. Equipped with Grade 5 pure ceramic bearings for unrivalled smooth running and minimal friction while freewheeling or pedalling.
• Axle system & Brakes: Fully designed for modern disc brake time trial bikes with a standard 12 x 142 mm thru axle rear hub and a reliable Center Lock disc rotor mount.
• Cassette compatibility: Readily available with a Shimano HG, SRAM XDR or Campagnolo freehub body to integrate seamlessly with any high-end electronic road groupset.
• Aesthetics: Available in a wide range of premium finishes, from subtle Matte Black and Gloss White to exclusive, eye-catching metallic options such as Chrome, Gold, Cobalt and Chameleon.
