The trend among the World Tour peloton is most teams will race the full season on disc brake bikes, leaving the good old rim brakes.
Caleb Ewan is racing on disc brakes type Ridley Noah Fast size XS (51cm) for the 2020 season. It is the same size as last year except for the fork rake.
The talented Australian sprinter I’d 165cm tall and has the less drag when sprinting against current world tour sprinters thank to his small size but also sprinting position.
The disc brake version is approximately 500gr heavier than the rim brake version due to the extra weight of the disc rotors and brake calipers.
The frame features Ridley’s “F-Tubing” which are teardrop shaped main tubes to optimize aerodynamics.
