TRP's 2.3mm rotors offer better heat dissipation and braking power.
You may need an adapter to fit these rotors depending on the fork you have on your bike. The OEM rotor on the Surron is 203mm, no adapter is needed for this size. You can find adapters here.
Fitment: TRP rotors work with both OEM and Charged Cycle Works front hubs (standard MTB spacing) but are not compatible with the proprietary SurRon rear hub spacing (our rear hubs were designed to match OEM specs). We run the larger TRP rotor up front and retain the OEM rotor in the rear on our personal bikes.
