TRP Disc Brake Rotor RS01E 2.3mm, 180-223mm

When every ounce of braking performance matters, the RS01E from TRP delivers — engineered for high-end trail, enduro and e-MTB use with one-piece design, increased stiffness and superior cooling.

Key Features

• One-piece stainless steel rotor, 2.3 mm thick (minimum wear to 1.8 mm) for durability under load.

• Significant torsional stiffness increase (approx. 47%) and improved cooling (approx. 8%) over standard rotors, reducing fade and warping.

• Multiple diameter variants available (180 mm, 203 mm, 220 mm, 223 mm) to suit everything from lightweight trail rigs to heavy-duty e-bikes.

• 6-bolt mounting, includes bolts for secure installation.

• Wear-indicator marks built into rotor so you can easily tell when replacement is needed.

Why It Matters for Serious Riders
For riders pushing hard on descents, carrying heavy loads on e-bikes, or requiring braking that doesn’t compromise when things get rough — the RS01E keeps things solid. The one-piece construction resists bending and vibration, meaning smoother feel at the lever, longer life and fewer unwanted noises. It’s a performance upgrade for those who don’t just ride — they demand.

Fitment & Usage Notes

• Intended for 6-bolt hub standards; confirm your wheel and frame clearance for chosen diameter.

• If upgrading from thinner rotors, check your caliper alignment, pad clearance and correct torque on rotor bolts.

• Used in heavy-duty scenarios (eMTB, downhill) especially beneficial; on lightweight road bikes the upgrade still gives peace of mind for durability and control.
