Improved over previous models. A lively upgrade for a lighter racer
Skip to view product specifications

Halo’s UK designers have been evolving their cost-effective wheels for years and the latest Mercury benefits from feedback from previous tests.


Halo has stuck with a narrow and deep rim that cuts through straight-line drag situations with a clean, efficient feel.

The wheels’ steering is slightly stubborn at higher speeds and the skinny tyre footprint leaves them feeling sharp on rough sections, though an extra four spokes in the front makes them much more obedient and consistent in corners than the previous model.


There’s still some softness in the rear if you’re sprinting out of the saddle, but they’re light for the money, which makes them a lively upgrade for lighter racers
