X-Ring Ti Integral 38T X-Hollowgram

38 teeth titanium chainring with technopolymer (Delrin) inserts and direct engage for Cannondale Hollowgram SL and Hollowgram SI cranksets. The kit doesn't require spider installation beacuse the outer chainring is directly engaged on the crank allowing a considerable weight saving and an optimal stiffness. The sophisticated CNC machinings assure superfast and precise shiftings, the special titanium grade 5 alloy assures a three times longer lifes than any other aluminium alloy chainring. The kit is composed by a main gear, four spacers, two shims and four Al7075 coloured (choose between red, gold, black, blue, green or silver) fixing bolts. The small chainring must be purchased separately, the 38 teeth compatible chainrings are X-Ring MTB Full Ti 26 x 64, 24 x 64 o 22 x 64. The crankset isn't included in the kit. The images are to be considered demonstrative.
