The idea behind the Spire Crank was to take the proven 2.5 piece system and combine it with a super tough. box-section arm design that will remain incredibly stiff and dent resistant.

After being pushed to its limits for about a year by Bruno Hoffman and the rest of the Eclat Pro team. the end result being a crank that is super strong and reliable that's built to shred.

The Spire is built from tubular heat-treated 4130 CrMo arms with a 22mm ultra hollow CrMo axle for maximum strenght and durability.
