SRAM Red crank 20 D1 172.5mm 48/35, 12-speed, DUB, WITHOUT BEARINGS

The SRAM RED® crankset paves the way for a fundamental design innovation: smaller chainrings and a wider-ratio cassette. This leads to smoother and faster front shifting and more usable gears for today's riders. The new configurations this makes possible improve cadence and efficiency and ensure crisp, clean and fast shifting - every time.

Features:

• Deep Range™ technology provides more gear range and a comfortable gear gradation, so you're always in the right gear
• improved derailleur shifting performance for razor-sharp and precise gear changes
• the unique chainring design results in a lighter, stiffer and more durable crankset
• DUB™ bottom bracket ensures durability and simplicity
• Can be upgraded with a power meter
• Technologies:
• AXS:
• AXS™ is SRAM's new electronic integration platform that connects electronic bike components and software. The SRAM AXS app allows you to see battery status, change component behavior, adjust controls, receive maintenance reminders and update firmware.

Flattop:
In order to offer Deep Range™ technology, SRAM had to develop a narrower chain. The unique link design of Flattop™ technology not only made this narrower chain possible, but also resulted in quieter operation, increased strength and longevity.

DUB:
The crankshaft and bottom bracket unit is at the heart of DUB™ technology. This is where stiffness meets durability. SRAM has gone a step further and made everything even simpler and better. It is largely the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drivetrain performance.

Deep Range:
Not only does it offer more gear range, but that range is better. It has "depth": A smoother, more useful gear gradation. Intelligent shift settings, made possible by AXS, bring the simplicity of a 1x drivetrain to 2x. So you always have the right gear and the transmission doesn't get in the way. Ride faster, more efficiently and more comfortably with Deep Range technology.
