Three spokes. One standout upgrade.
Transform the look of your Java Neo with a full-carbon, three-spoke front-and-rear wheelset. At approximately 1,181 g for the bare pair (including the rear freehub), it is a distinctive upgrade in your choice of glossy or matte finishes. Bike Atrium installation is included.
FULL CARBON · 3-SPOKE · FRONT + REAR SET
20-inch (ETRTO 406) | Approx. 1,181 g bare pair | Center Lock hubs | Installation included
Important before installation
A pair of Center Lock rotors is required
The Rpantahi wheelset uses Center Lock disc-rotor mounts. The Java Neo's original rotors use 6-bolt mounts, so they cannot be transferred directly onto these wheels. You will need two compatible Center Lock rotors (front and rear). Rotors are not included with this wheelset; Bike Atrium wheelset installation is included.
