When SRAM launched the new AXS road bike groups, they introduced new gearing patterns and chainring combinations to optimize the ring-plus-cassette ratios. But the largest officially available double chainring was a 50/37.

Their sponsored pro teams, however, wanted more. So SRAM was making custom combinations with bigger gears. UCI rules, however, state that anything the pros are running needs to also be available for sale to the public…or at least heading toward production.

So, SRAM is adding three new Red eTap AXS 12-speed double chainring sizes to the lineup. Here’s everything you can now get:



sram red etap axs powermeter chainrings are integrated into a single piece

These new combinations are only offered for aftermarket, not OEM, and will only be sold with the integrated Quarq powermeter spider. Which means they’re part of SRAM’s power meter exchange program (50% of replacements) since the power meter and chainrings are built into a single part.

Retail prices are MSRP: $1,349/ €1300*/ £1160 (*includes VAT), which sounds expensive…it’s a $150 premium over the original Quarq-equipped chainrings. That’s because they come with a special two-position eTap AXS front derailleur to handle the taller gearing.

If you were building a bike from scratch, and you wanted monster gearing, that’s actually a bit of a deal since the front derailleur normally runs $400.

Available starting March 24, 2021.

    Not a sram guy in the slightest but that’s sort of the going rate for electronic front derailleurs, Dura-Ace di2 front mechs are like $50 cheaper that being said prefer di2 way more than eTap even in its current iteration.

      $50 with no power meter. Granted, i do not want or care about power meters but at least if you pay for a tire rotation, they’ll change your oil for free.

    I don’t like the idea of a 10 either. But until SRAM starts to make 12 speed 12-28 or 12-32 you are stuck with the small front chainrings as well if you want to be able to use the full range.

    I’ve got the standard 48/35T on my bike with the 10-33T. I only top out when I get to +75km/h. So unless you are racing I just can’t see why anyone would need the larger chainrings. If I have any complaint it’s being limited to 33 on the back (20% grades are common where I live).

    Further evidence that SRAM is taking the wrong drugs, though I guess 56×10 might be useful with 16-20″ wheels…

      Presumably Shimano Dura Ace 12-Speed will have a 10T as well….but somehow everyone will be OK with Shimano doing it….its only a problem when Sram does it. (As evidenced by the fact that noone cares that Campy does it too on their 13-Spd.
