Shimano Deore M615 review£89.99

Durable budget crankset

BikeRadar score4/5

Shimano's Deore crankset is a top-value choice with excellent shifting and durability. It uses cost-saving cold forged arms rather than the Hollowtech II arms of SLX and upwards, but they still feel stiff and sturdy, and can take a hammering.

They do add 73g over SLX though. The shaped and pinned chainrings are the same, so shifting performance is smooth even when climbing hard. The lower grade BB is comparable with what you get on top cranks from most other brands too. Like other Shimano cranks, there’s no BB30 or official single-ring option, and the black version scuffs up quickly.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
