The new Storck Powerarms SL cranks have been unveiled. They are ultra light and look flashier than the cranks they’re based on: THM Clavicula.
These cranks hit the scale with only 445g, which is 20g heavier than the Clavicula. The increased weigh is due to the main difference between both arms – the materials used. The Storck’s axle is made out of aluminium and the arm itself is open on the chainring side. The original THM model is entirely in carbon and is not ope.
