HollowGram R45 700c Carbon CL Disc Tubeless Shimano Rear Wheel

The HollowGram R45 wheelset was developed to meet the demands of today’s cyclists by unlocking the speed and performance potential that a high-calibre wheelset can offer, all while providing exceptional versatility.

Utilising our expertise in aerodynamics the 45mm deep rim profile has been optimised to provide speed across every type of terrain along with aerodynamic efficiency and crosswind stability.

Combined with the tubeless ready 21-mm internal width, the R45 rim is the perfect match for use with modern, wider tyres allowing the use of lower pressures to reduce rolling resistance and provide a more compliant ride. The rim offers outstanding sidewall support and creates a tyre profile that offers confident and predictable handling in all conditions.

Key Features:

• 45mm rim depth provides best combination of speed, aerodynamics, stability and weight.
• 32mm outer rim width optimises airflow of a wider tyre allowing it to cleanly reattach to the rim and reduce drag.
• 21mm internal width is perfect for use with modern, wider tires, providing them with the right amount of sidewall support to facilitate surefooted handling in all conditions.
• 21 points of hub engagement with 3 sprung loaded pawls offer fast engagement and efficient power transfer
• Easily set up to access benefits of a tubeless system
• Compatible with XDR cassettes using replacement freehub body (K81010)
