Details

Gossamer Pro is FSA's high-end alloy crank family, and the AGX+ version is set up for gravel. The arms are cold forged from AL6061 and the spindle is forged AL7050. The AGX+ geometry uses a wider Q-factor and chainline than a road crank, which gives room for wide gravel tyres and a straighter chain on a wide-range cassette.

Fit and compatibility

It uses a 24mm MegaExo spindle, so it needs a 24mm MegaExo-compatible bottom bracket for your frame's shell (sold separately). The 40T setup is direct mount.

Fitting

Fitting a crankset means removing the old crank and bottom bracket, checking the frame's shell, and setting the correct preload on the non-drive arm. If you'd rather not do it at home, our workshop can fit it and check the chainline and shifting at the same time.

Not sure which bottom bracket or crank length you need? Send us your frame model and current setup and we'll check it before you order.
