An all time favourite of the BSD line up- the Substance XL cranks just got better! These are a new and updated version of the Substance XL crank with a new invest cast boss design that sits fully flush with the crank arm completely eliminating sharp edges around the ankles. The rectagular arms offer up loads of strength and stiffness whilst increasing grindability and a BSD Mid 24mm bottom bracket has been included- how good is that!
FLUSH BOSS DESIGN
BSD has designed the Substance XL V2 crank arm with an invest cast boss that sits super flush eliminating sharp edges that can whack your ankles.
OVERSIZED HOLLOW SPINDLE
The 24mm diameter spindle is stiffer and stronger but being hollow, does not add any extra weight to the cranks compared to 22mm versions.
The Substance XL V2 crank features heat treated 4130 chromoly arms with a rectangular cross section for increased stiffness and grindability.
