From the start, Craftworx set out to create
dynamically balanced wheels that deliver an exceptional riding experience. The ULTIMA GEN3 Series is the culmination of over a decade of relentless innovation, combining advanced materials, cutting-edge manufacturing techniques, and modern, minimalist styling.
The sleek, clean lines and refined design aren’t just for show—they embody the confidence, precision, and performance these wheels deliver on every ride.
CRAFTWORX ULTIMA SL
PREMIUM ALLOY RIMS
Crafted from advanced T6 6069 aluminum alloy, the Ultima SL rims achieve the perfect balance of strength, lightweight performance, and ride compliance. With a 20mm internal width, they are designed to pair seamlessly with 28mm–32mm tires.
Running tires in this range increases volume,
providing a more stable and comfortable ride while reducing rolling resistance for greater efficiency. The wider setup flattens the contact patch, enhancing grip, control, and overall handling.
CRAFTWORX R-SERIES
E-BIKE PERFORMANCE HUBS
The R-Series ratchet drive freehub system features a 36-tooth mechanism designed to withstand the high torque demands of electric bikes.
This heavy-duty hub design, paired with 32 spokes provides reliable power transfer, increased durability, and easier maintenance for long lasting performance.
