Brakes/Drivetrain

When SRAM found ways to make their lightest and stiffest crank even lighter, they went for it. A new process further grams from the hollow carbon arms. Plus they're offering more crankarm lengths than ever before to ensure this crank works for you. - Hollow carbon crank arms are 29g lighter than previous generation - 8-bolt interface compatible with power and non-power AXS spiders and integrated chainrings (Spiders and Chainrings sold separately) - DUB bottom bracket adds durability and simplicity (Sold separately) - Includes DUB Wide Spacer kit (2.5/3.0/4.5/5.5 mm) - 150mm Q-factor / 47.5mm chainline

- Thinline: Thinner, longer molded pads for extra clearance and easy adjustment - Red: semi-aggressive compound for good performance - Salmon: aggressive compound for extreme weather conditions - Dual: combination of Salmon and Black compounds for more controlled, smoother stopping

Meet the new standard for hard-hitting, heavy-duty braking. We added 15% extra piston power and 30% more volume in the lever reservoir, ensuring peak performance for the full run. And with SwingLink and Lever Pivot Bearing technologies, lever feel remains smooth and progressive, no matter how hard the pull. Go deeper and grab more power. - Designed specifically for heavy-duty demands. - Pivot bearing offers crisp lever feel and a fatigue-free ride. - Metallic pads come standard for more power and longer wear.

Sometimes less is more. With the 10-speeds, an 11-48T range, and evenly spaced gear steps, the ADVENT X cassette allows riders to shift less often to find the right gear, while still having enough range to ride what they want. Fewer cogs also means less weight and a wider chain for better mud shedding. It even fits on standard 10-speed freehub bodies so you don't need to buy new wheels for no reason. 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

Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. Plus-type derailleurs use a lever-actuated clutch spring to prevent chain slap, reduce noise while on the trail, and improve chain engagement when riding over rough terrain. Sealed pulley bearings keep things spinning smoothly, and wide plate construction prevents the derailleur from getting clogged with mud and debris.

Three decades ago, SRAM was founded on a product called Grip Shift and an idea that shifting a bike should be easier, better and more intuitive. It’s more advanced than the original, but the XX1 Eagle Grip Shift follows in the same tradition of making shifting easier, better and more intuitive. The XX1 Eagle Grip Shift system includes robust internals that make it more durable and its shifting performance more precise. But just like the original, it is total control in the palm of your hand.

SRAM's MRX Comp Twist Shifters are simple to use and offer solid shifting and reliable construction. Shifting one gear or the whole range is simple with just a twist of the wrist. They shift a 2:1 Shimano rear derailleur and a SRAM or Shimano derailleur up front.

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.
