Halo Gravitas Alloy Mountain Bike Rims - Stealth Black

Season:2025

Brand:Halo

Code:rmha-gravitas-29SGRNthBLK

The Gravitas has been specially designed and tested for the demanding conditions of the Downhill world cup circuit and the most extreme Enduro races in the series. Aiming to provide riders with the confidence to tackle any challenging descent.

A unique design feature of the Gravitas is the honed 27.5mm internal width (33mm external). This width allows for larger sidewall support for the tyres, which is beneficial for maintaining stability and preventing tyre roll during aggressive riding. Despite a reasonably wide internal width, the Gravitas has been designed to remain narrow enough to minimise unnecessary collisions with rocks and other obstacles on the trail.

Utilising an asymmetric design that has been tried and tested to deliver optimal performance. This design approach allows for a wheel package that excels in descents while minimising unnecessary bulk in areas where it is not needed. To address the differences in wall length and strength resulting from the asymmetric design, the wall thicknesses of the Gravitas wheels have been proportioned accordingly. This ensures that impact forces are balanced out equally, contributing to the overall durability and performance of the wheels.

The Gravitas offers an incredible package for a 575g rim (27.5”), without compromising on strength and durability. They have been specially engineered to excel on the roughest terrain, providing riders with the confidence to tackle anything in their way.
