FSA Gossamer Pro BB386EVO Crankset – 1×10/11-speed – 42 Teeth

The FSA Gossamer Pro is a high-end 1-speed crankset for aluminium lovers. With an impressive history of wins on the brutal cobbles of Paris-Roubaix, it needs no further introduction – yet the details shouldn’t be ignored.

The cold-forged aluminum 6061-T6 arms are heavily scalloped for maximum strength to weight ratio and the versatile BB368EVO spindle is forged from even stronger aluminium 7050. In combination with the appropriate bottom bracket, the 30 mm axle is compatible to almost any frame type.

The chainring is made of high-strength, CNC-machined aluminium 7075 and its MegaTooth profile provides a safe chain retention also when the chain is tilted or the weather turns bad.

 

MegaTooth

The teeth of MegaTooth chainrings are longer than standard with an asymmetric profile shape, a diamond-shaped cross-section and a unique system of alternating thick then thin teeth. This allows for smooth chain engagement, meaning that the chain always remains in close contact with the chainring to give you the most reliable and positive drive possible.
