The RS7 cranks are slender, yet they boast high strength and what seems like endless durability – testament to Middleburn’s belief in the RS7 is the lifetime warranty.

The cranks are available in both ISIS and square-tapered bottom bracket versions and Middleburn make spiders for all possible chainring configurations.

The action feels very positive, with every ounce of power put in by the rider being efficiently transferred to the rear wheel. Most pedals, chainrings or chainguides will give way before the RS7s will even consider bending, and considering the weight (474g), this is quite some achievement.
