Deep in the hills of Santa Cruz, cyclists are brought to their knees by a nasty, four mile, 1800 ft. climb named Alba Road. This respected ascent was the inspiration for our Alba road crank. With its shapely forged-alloy arms connected to our M30 alloy spindle, choice of smooth-shifting Praxis Works cold forged chainrings and M30 bottom brackets (required and sold separately), the Alba is ready for anything you pedal up against. The Alba M30 road bike crank can be installed in a BSA, BB86, 386EVO, BB30, PF30, T47, BBRight or older Specialized OSBB road frame.Key Features:Technology:Alloy Arms.M30 Spindle/Bottom Bracket System.2x NEW LT2 X-RingsLearn More Here2x LevaTime® shifting techLearn More Here1x Wavetooth profile ringsLearn More HereCompatibility NotesThe Alba M30 road crank uses our Praxis M30 spindle/BB.
