Cannondale SI Lock Ring
$27.00
By Cannondale
Original alloy Cannondale lockring used to fasten the spider to the crankarm on Hollowgram cranks.
Compatible with all Cannondale BB30 Hollowgram cranks, and was redesigned to fit Evo's press-fit bottom bracket. If you have an Evo you need this lockring, because the old one does not fit.
Kit includes one alloy lockring and does NOT include Loctite required at time of installation. Requires KT012 tool for installation and removal.
