The SRM THM Carbon Crank Arms offer a lightweight upgrade for riders using the SRM Origin power meter system. Manufactured in Germany by THM, these carbon crank arms combine low weight with a stiff, performance-focused design. At just 218 grams per pair without the spindle, they are SRM’s lightest fully modular Origin crank option. Their modular construction allows riders to replace their existing crank arms while retaining compatible Origin components. Available in lengths from 160mm to 175mm, the THM crank arms support multiple SRM Origin Road configurations.
SRM Origin Crank Caps sold separately.
This crankset is compatible with 24 mm, 29 mm (DUB) and 30 mm SRM Origin spindles.
These SRM THM Carbon Crank Arms are incredibly light and designed for SRM Origin power meters. Our staff recommends this crankset to riders who are looking for the lightest cranks available with their SRM power meter. This is a premium crankset, but one that will provide weight and stiffness upgrades for any rider.
