Great strength-to-weight ratio at a reasonable price – just watch your knees!

FSA’s Gravity range of downhill and freeride components has been around for a few years now and the parts are a regular sight on complete bike builds.

The Gravity Light stem is forged from 2014-T3 aluminium and CNC machine finished to give it plenty of strength and stiffness along with some super-sleek looks.

It can be flipped to increase or decrease the rise by six degrees and is available in 50mm to 105mm lengths, as well as a 1.5in steerer version. We decided to run the 90mm stem, which weighs in at just under 200g – refreshing for a unit designed to take some abuse.

The Gravity Light is finished nicely with laser etched logos and torque values. Using four opposing 4mm Allen keys, the face plate is easy to tighten evenly and all threads and bolts heads were flawless.

It’s not cheap, but it offers plenty of torsional stiffness and we found it worked fantastically well with FSA’s Gravity Light 40mm-rise bar. The only minor complaint during testing was the angular profile of the rear of the part – not the friendliest to misplaced knees and other body parts!
