The world's lightest commercially available forged aluminium alloy 18".
At 6.75 kg / 14.85 lbs, in 18x9 ET39 specification.
At 7.26 kg / 16.00 lbs, in 19x8.5 ET35 specification.
The RRT-XTREMIST is the lightest and one of the stiffest forged wheels in the market.
The concept behind the RRT-XTREMIST is simple; we utilize well proven engineering structures coupled with advance CNC machining and computer aided simulation techniques, while ignoring production time considerations.
This enables us to create the stiffest and lightest structure that represents a true evolution in wheel performance.
The RRT-XTREMIST has extremely large moment of inertial spokes compared to its competition. This establishes an extremely strong structure.
Weight is removed though 5-Axis CNC machining, creating the deepest radius-ed I-beam cut in the industry.
Although this meant that the production time per rim is increased, our goal has always been performance and technical superiority instead of profitability.
We design, customize and manufacture all our wheels in-house. This provides us with greater innovation and the usage of advanced techniques that large-scale companies may not use due to cost.
The RRT-XTREMIST features the following design applications unseen in most forged wheels:
Mounting hole to spoke webbing (for higher torque transfer and spoke stability)
Super deep radius I-beam cut (for a large moment of inertia with minimal amount of weight)
Hole through spoke with support spar (for removal of excess material while the spar reinforces the spoke, creating a innovative truss structure)
Pocketing (for removal of unwanted material to further lighten the wheel)
Large spoke to barrel asymmetric radius fillets (these wide fillets allow for stable spoke to barrel bracing, optimized in size by computer-aided simulations. To enhance impact resistance, superior stiffness and torque loading capacity)
The RRT-XTREMIST is the coalescence of engineering, innovation and advanced manufacturing techniques, synergizing everything into a package that can be truly called:
