SRAM's all-new 12-speed Red DUB crankset is the result of systematic changes to the company's leading road group. Thanks to the update of the Red e
Tap line this allowed SRAM to completely change the crank design and, among other things fundamentally change the concept of transmission. We'll be the first to admit that SRAM front shifting was, ahem lagging behind competitors and with the advent of the new system, these times have passed.

Naturally hollow arms are made of carbon for durability rigidity and light weight. SRAM uses a patented design which increases the thickness in critical areas, and the conical terraced carbon architecture reduces weight elsewhere. Next up is the oversized DUB aluminum spindle. , first appearing on his mountain bands now available on the road for the first time. This standard significantly improves bottom bracket bearing durability and expands frame compatibility without sacrificing rigidity.

But perhaps The most significant change to this crank is the new sprockets. These all-new direct mount rings are made from a single piece of lightweight aluminum , making them as rigid as possible for faster clear and consistent gear shifting. Rings available in 46/33 teeth options , 48/35 teeth and 50/37 teeth in which you will notice two things: a constant change to 13 teeth between small and large rings and variations with smaller overall teeth.

In contrast to 16-tooth jumps compact (50/34t) and medium-compact (52/36t) or even 14-tooth jumps with a persistent standard (53/39t) The 13-tooth jump allows for smoother, faster shifting at the front with fewer compensating shifts at the rear after shifting. All this thanks to a wider range of cassettes offered by the new 12-speed cassette and its 10-tooth starting sprocket. SRAM calls this X-Range gear technology we call her amazing. Not only does this provide more useful shift options and smoother shifting which improves cadence and efficiency but also the gear changes are always crisp, clean and fast.

Finally connecting rods can be easily upgraded to become a power meter in the future with Red AXS updates from subsidiary Quarq.
