Developed specifically for the demands of triathlon, time trial and cyclocross, the SRAM Red1 12 Speed Chainset provides racers with the right mix of features, aerodynamics, durability and simplicity. Ready for racing, this versatile 12 speed chainset features a lightweight carbon crankarm construction, which means that riders can enjoy its exceptional stiffness when climbing without any unnecessary weight holding them back when descending. SRAM has also equipped this model with a durable aluminium chainring with a laser-etched finish, giving it further strength and longevity on the more demanding of course conditions. Thanks to its single-ring set-up with renowned SRAM technologies, it simplifies functionality while also keeping its overall weight reduced. As a result, it's great choice of upgrade for quick acceleration and smoother performance on your ride.

12 Speed Chainset with X-SYNC Chainring Technology
Whether you're into triathlon, time trial or cyclocross racing, this chainset is fine-tuned to provide the highest level of performance and durability. Thanks to its X-SYNC technology, this model's chainring features a wide/narrow tooth profile for maximum chain control, whatever the course conditions. Another highlight is its kitted out with a DUB compatible spindle interface, so riders can enjoy a simpler, stiffer and more secure connection between their chainring, cranks and bottom bracket.
- Single-ring drivetrain simplifies functionality and reduces weight
- 48 and 50t variants feature direct mount aero chainrings for better aerodynamics
- Non-aero chainrings can be installed with a single tool, making gearing changes a breeze
- SRAM X-SYNC_x0099_ wide-tooth, narrow-tooth chainring technology provides maximum chain control
- Laser-etched chainring finish is more durable
- DUB_x0099_ bottom bracket adds durability, simplicity and broad compatibility
- Can be upgraded to a power meter

Technologies:
X-SYNC: SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.

DUB: The relationship between bottom bracket spindle and bearing is the core of DUB technology. It_x0092_s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler_x0097_better integrating the relationship between chainring, crank, spindle and bottom bracket. It_x0092_s this approach to developing a complete system that equals better drivetrain performance. Bottom bracket sold separately.

Exogram:
SRAM's Hollow Carbon Construction starts in the crank arm and extends into the crank_x0092_s spider, maximising the stiffness to weight ratio.

X-Range:Road bikes are faster and more capable than ever before, and riders are expanding what_x0092_s possible with drop bar bikes. X-Range is gearing for today_x0092_s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression. With X-Range, you_x0092_re always in the right gear.
