EXAR Ultra wheelset is designed for ultimate performance.
The wheelset is fully equipped with top-level materials from spokes to bearing, creating elaborate hub and rim. No matter in terms of appearance, quality or speed, EXAR Ultra has been improved to a higher level. The difference in details will take riders to the lead on the field.
- The EXAR Ultra wheelset applies HI-MOD T800 carbon fiber, allowing for a very light wheelset. DB405 -1290g ±3% and DB508 - 1375g ±3%.
- A 30mm width rim and 23mm internal width ensures optimal aerodynamic performance when installing 28-32c tires. It creates a flatter aerodynamic surface and enhances cycling comfort.
- The low front wheel rim depth and a high rear wheel rim depth ensures high inertia of the rear wheel, also keeping the controllability of the front wheel.
- EXAR Ultra carbon fiber wheelset features HI-MOD T800 carbon fiber spokes. Carbon fiber spokes have higher tensile strength and can withstand 30% more tensile force.
- Ceramic Bearings ensures smooth and durable hubs. It is lightweight with low resistance.
- Flat Engagement Ratchet Design - a 36-tooth flat ratchet has tighter engagement with a larger surface. This can make the ratchet more durable, with fast and precise engagement.
- Professionally Tested and Approved by UCI.
