Description

2-pcs design cranks made of heat-treated Cr-Mo 4130 steel with 22mm spindle and 48 splines. RHD/LHD compatible. Two sprocket holes to fit all sprocket sizes. Small gusset to make the pedals assembly area stronger. Includes arms, spindle (welded to the right arm), 2 spindle bolts (alu 7075-T6 and Cr-Mo), 2 sprocket bolts (bigger one is hollow) and assembly/disassembly tool.

Available with 2 spindle lengths:
- 160mm (Thorn MTB) designed to work with Euro external bearings (like Dartmoor Euro eX BB 22mm) with 68mm or 73mm BB shells to create an extra strong and efficient combination with frames like Two6Player or Shine,
- 150mm (Thorn BMX) perfectly working with Spanish or MID BB equipped frames as well as standard Euro BB to minimize number of required spacers for such kind of frames and keep correct chain line.
