The Firex Team shares the same crankarms as the Firex SL, but uses the same nickel-plated chainrings featured on our top-of-the-line Stylo Team crankset. Like the Firex SL, the crankarms are bigger, stronger, and lighter than the 2002 Firex crankset due to the AL-66 forged alloy construction. AL-66 alloy is 35% stronger than AL-6061-T6, the aluminum alloy most of Truvativ's competitors use in their crankarms. We've added new chamfering and disengagement features to all our rings for easier, chainsuck-free downshifting and improved upshifting. ISIS Drive interface only. For cross-country use. Blast Black finish.
