5-Spoke Direct Mount for SRAM GXP Cranks
SDM chainrings fit on SRAM cranksets with removable spiders: S2200, S2210, X9, X0, X01, XX1, X1 1400, Truvativ AKA Cranksets (GXP version), and newer S1400 (or X7) . If the crankarm and the spider are all made from the same piece of aluminum it is not removable.
Chainline is 50mm on all rings (on a GXP or BB30 long spindle crankset). All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum.
Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
Product weights: 26t - 52g, 28t - 59g, 30t - 65g, 32t - 70g, 34t - 75g, 36t - 81g Color: Black
These can also be used on a BB30 / PF30 long spindle crankset -- the 3rd product picture shows you how to determine if you need this ring or the Short Spindle BB30. This SDM ring is dished in ~6mm, whereas the BB30 short spindle ring is flat.
