SRAM has received a number of inquiries lately regarding RockShox fork and disc brake rotor sizes. Following is a list of all RockShox fork platforms and the maximum recommended disc brake rotor size.

Fork Platform Maximum Recommended Rotor Size
GPS 165mm
Judy 165mm
Pilot 165mm
SID 165mm
Duke 210mm
Psylo 210mm
Boxxer 210mm

SRAM tests the structural integrity of all RockShox forks to that of the 210mm disc brake rotor size. However, other factors, including fork stiffness, bushing design, and intended use are considered when determining maximum rotor size.
