True competitors are always looking for a performance advantage — a relentless pursuit of equipment that is lighter, stiffer, stronger, and more durable. To create the best drivetrain possible, we re-examined and re-engineered our crankset design. Our all-new XX1 Eagle CARBON TUNED crankset is our lightest, stiffest, and strongest to date. DUB technology enhances this by simplifying the relationship of the spindle to the bottom bracket and redefining the measure of durability.

In short, it's everything you want in a high-end drivetrain. - Two alloy large cogs and a full alloy spider eliminate unwanted weight - Ramped cogs aid in shifting under load - Continuously molded construction maintains straightness and durability - Compatible with standard HG freehub bodies and 10-speed chains - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Cassette Cogs: 11-13-15-18-21-24-28-34-40-48

An issue many people ran into when they began using 1x setups was chain retention with the front chainring. In the beginning of the 1x movement, many companies dealt with this by using aftermarket chain keepers that somehow bolted to the frame. Many people discovered that using a narrow-wide chainring in conjunction with some type of 'clutch' rear derailleur helped abate or eliminate these chain-jumping issues. Narrow-wide rings use alternating tooth profiles that more positively engage the chain and help control a deflecting chain in bumpy conditions. Your friends at Surly have partnered with SRAM to bring you stainless steel X-Sync chainrings. Stainless Steel is durable. This durability is pretty useful when you're talking about the one ring that is bearing the brunt of all your miles.

The new SRAM DUB crank standard, built on a 28.99mm spindle, allows for a more contamination-resistant BB design, while retaining the ultra-efficient & long-lasting qualities CeramicSpeed Bottom Brackets are known for. With an integrated dust cover for all models, the snug & secure fit not only fully protects the face of the bearing, but also delivers exceptional performance without any sacrifices. CeramicSpeed hand-built bearings carry the load from crank to frame with unparalleled durability & efficiency. The SRAM DUB crank spindle requires the bearing contact points to be in a set and designated width, and all CeramicSpeed bottom Bracket options perfectly match the bearing placement on the crank spindle with the required frame interface for nearly any model of bike. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the product. The ITA for SRAM DUB Road comes in two bearing options. The first option is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second option is our Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag.
