Lastly, but functionally definitely not least, are the crank spiders. If you’re running Truvativ (SRAM) X0, X9, S2210, or S1400 cranks, the spider won’t let you fit a Gamut chain guide (or any other one, for that matter) – which is where this comes in. It replaces your normal one, with 104 BCD for the Gamut rings, and comes in either 1×10 or 2×10 flavours. It works with either BB30 or GXP, and weighs 66g.
