External bottom brackets are great, but the cranks aren't always tough enough for the abuse that some riders dish out. For DMR, though, making tough stuff is what they do...
These Extype cranks are compatible with most external bottom brackets - Shimano, FSA, Truvativ and so on, and include left crank arm, right arm with axle and four-arm spider. The arms are available in 170 and 175mm options (in black and chrome). You can also buy five-arm compact spiders, and spline drive chainrings to ensure compatibility with what you're riding.
These cranks are solid, look great, and don't weigh much more than some regular cranks. Heavy riders can ride 'em with confidence.
