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.

  • Carbon crankarms add stiffness while reducing weight
  • Integrated carbon spider eliminates hardware, increases stiffness, and reduces weight
  • SRAM Red PowerGlide chainrings for pro-grade shifting and stiffness
  • BB30 bottom bracket (available separately) utilizes oversized spindle and in-frame bearings for greater stiffness and a 20% weight reduction

Is there a difference between the 2011 red bb30 crankset compared to the following years? And would a 2011 red bb30 crankset fit on a 2012 road bike?

SRAM Red Black crankset listed here has 'bottom bracket sold separately' My BB30 frame has FSA Omega crankset. Is my current bottom bracket compatible or do I absolutely need to purchase new bottom bracket if I go for SRAM Red Black?

If I already have a frame that is BB30 equiped with existing cranks attached, would I need to purchase something in addition to these cranks? Or will these cranks attach to the bike right out of the box?

Does this crankset work when combined with an Ultegra gruppo? I have an Ultegra gruppo but I'm converting to a BB30 bike frame. So I'm wondering if I'd still be able to keep my group set if I just change over to this crank.

Yes, the crankset should work fine with your Ultegra group. Just make sure you have BB30 bearings and not the outboard cups that Shimano traditionally uses.
