If you ever thought that Sram's Red Crankset looked too sterile with their grey chainrings, have a look at this Red Black BB30 Crankset. Functionally, it's the very same, though the new black chainrings give it a more sinister appearance. And since SRAM is a forward-looking company, they wanted to offer their top-of-the-line crankset in a version compatible with BB30 framesets. Please note that if you don't have a BB30-specific frame, these cranks won't work (just order the standard Red Black crankset instead!)

Like the standard crankset, with the BB30 version you'll get PowerGlide chainrings. They're machined from 7075-T6 aluminum to be plenty stiff so more of your power turns into speed instead of component flex. But it's not just about the added power-transfer that comes with flex-free chainrings -- since PowerGlide chainrings don't flex, they pick up and drop off the chain with unparalleled ease, And in addition to looking fantastically PRO, the hard anodized Black chainrings wear well and will give you many miles of smooth shifts.

The BB30 design offers a number of benefits over standard external bearing cranksets, SRAM's GXP design included. Perhaps most importantly, you'll get a narrower crank at the spindle. This gives you significantly more ankle and heel clearance, so your shoes won't as readily rub the carbon fiber crankarms if you pedal with your heels in/toes out. The shorter, larger diameter spindle is also 10% stiffer, and it's 20% lighter as well.

The Red Black BB30 Crankset is available in 170, 172.5, and 175mm crankarm lengths, and it's available in 53/39 and 50/34 chainring configurations. One final note: SRAM Red compact Cranksets don't require a special compact-specific front derailleur. You use the same Red front derailleur for the 53/39 as you do for the 50/34. Bottom Bracket NOT included.
