FSA Afterburner mountain bike crankset review£199.99

Tough triple transmission

BikeRadar score3/5

The smooth and shiny Afterburner certainly has looks dialled. Polished silver is a good choice for cranks – your heels usually turn them shiny after a while anyway.

Fortunately, construction details back up the aesthetics. FSA use hollow-forged crank arms, putting the metal where it’s best for stiffness. They've worked on low weight too, with machined chainrings and even 7075 aluminium Torx chainring bolts.

You get a suitable Torx driver in the box, which is a nice touch. The Afterburner can’t match the weight of its cheaper Shimano rivals but it’s still pretty competitive. And FSA’s CNC-machined 7075 chainrings deliver impressively slick shifting.

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.
