The Halo Gravitas 27.5 Disc Rim is built for riders who push their trail bikes to the limit and expect their gear to keep up. With a wide 27.5mm internal width, this rim gives modern tires the room they need to deliver unbeatable traction and control on every descent. Whether grinding up climbs or charging through technical downhill sections, the Gravitas strikes the perfect balance between strength, weight, and responsiveness.
Its asymmetric design is the secret to a stronger, longer-lasting wheel build. By equalizing spoke tension across both sides, the Gravitas improves stiffness and durability without adding unnecessary grams. Halo fine-tuned the wall thickness to perfectly distribute impact forces, so you get the benefits of an offset rim — improved handling, balanced spoke load, and better power transfer — with zero compromise.
27.5mm internal width boosts tire volume for more grip and control.
Asymmetric profile balances spoke tension for a stronger, stiffer wheel build.
Optimized wall thickness ensures even impact resistance and long-term durability.
Lightweight yet tough design excels on both climbs and descents.
For riders seeking a rim that rewards precision and confidence on every ride, the Halo Gravitas 27.5 Disc Rim sets a new benchmark in trail performance.
