In addition to a new range of G-Spec Trail mountain bike brakes for human-powered riding, TRP has a new G-Spec eMTB brakeset that gets revised tuning and thicker rotors to better handle the increased weight and power coming from e-bikes. They get a 2.3mm thick rotor -about 30% thicker than their standard rotors- which they say helps keep heat about 9% lower.
That’s too thick for regular calipers, so you can’t swap them in for your regular mountain bike brakes. To make it work, the e-calipers start with the pads’ retraction point set a little wider. They used FEA to optimize the design for heat management without giving up power. Uses the same lever as the G-Spec Trail but with different branding.
