Lightning Carbon Cranks

The long awaited crank from Lightning has finally seen the light of day. Often copied, replicated and licensed, Lightning's revolutionary crank is now available for threaded bottom brackets. The crank features carbon arms with an aluminum spider, joined in the center by a Hirst Joint (ala Campagnolo). The bottom bracket cups are secured by a genius knurled design to aid in the threading process, no superfluous installation tool required. Lightning claims a q-factor of 149mm, however the pedal threads 2.5mm into the arm on either side, reducing the q-factor to a scant 144mm. Weight for a 172.5mm SL set is 445g including BB. Clydesdale sets are also available. Ceramic bearing upgrades are also available
