Cranks are among the most important parts of the whole bike concept. Thanks to them we can ride hard! We need to trust them as much as we do when it comes to brakes or tires on the steep tracks. Through the cranks our energy flows and pushes the wheels ahead. They need to be stiff and reliable. Just like the Rock cranks for 2014. 2-pcs construction with an integrated 24mm axle make them trustworthy and trouble-free in every condition. The 10-splines design combined with 2-bolt left arm guarantees a really strong connection. They come with a dedicated 36T aluminium chainring that will do the hard job of giving your strength to the chain and thanks to the steel inserts your pedals will work safely for a long time. Please notice they come together with the external bearings fully compatible with the Shimano standard and frames with 68mm or 73mm BB shells. The whole set weights about 915 grams (without bearings). So if you look for the entry level MTB cranks that will not ruin your budget and will look really cool in your bike - Rock is for you !!
