FSA Gravity Light chainset review£249.95

Downhill crankset with bashring included

BikeRadar score2.5/5

This chunky unit from FSA’s downhill division has been around for a while but we’ve found it’s not as strong as its weight might suggest.

The hollow aluminium arms and spider are forged in one piece, the steel axle is matched with steel pedal inserts, and there’s a thick polycarbonate bashring included.

There’s a spacer ring for the inner chainring, and long upshift bulges with steel ‘helper’ pins move the chain up reasonably easily, if not as smoothly as on Shimano rings. FSA bottom brackets are good though, and the crankset comes in standard and BB30 versions.

While it’s still relatively ‘light’ in ‘gravity’ terms, we’ve had a few reports and experience of it bending more easily than other downhill-orientated setups, at which point the weight looks high.

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.
