When it comes to adventurous riding, a wider gear range is often better. With 9 speed and a 11-42T range, the ADVENT cassette has the low gears you need to get up and the high gears to get back down. The steps between gears are optimized to give an even spread in gear ratios, reducing the need for double-shifting to find the right gear. - Machined aluminum large cog for reduced weight - Carbon steel cogs are continuously forged for strength and shifting accuracy - Compatible with standard freehub bodies - Surface Finish: ED Black / Anodized Black - Combination: 11-13-15-18-21-24-28-34-42

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

The first kit to convert SRAM XD driver-equipped wheels for singlespeed use! Problem Solver's has a disproportionately large percentage of singlespeed enthusiasts in their ranks, so it’s only natural that when SRAM introduced a new freehub body in order to accommodate a larger number of gears, they started thinking about how to convert it to one gear. The Zinger provides chainline adjustability and a broad range of cog sizes for whatever type of bike you’re lookin’ to simplify.

Featuring 10–24 gearing with two-tooth steps, the 7-speed XG-795 DH Cassette is optimized for the gear jumps that downhill riders want, eliminating the need for double or triple shifts. And because it’s so compact, it’s also light—the lightest cassette in existence, in fact, at just 136 grams. Compatible with any XD wheel, the Mini Block X-Dome technology integrates flawlessly with your SRAM 1X drivetrain. Going from zero to hero has never been faster.

It's the final piece in the drivetrain puzzle, and paired with SRAM RED eTap and RED rear derailleurs, SRAM's XG-1190 cassette delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear. - Compatible with SRAM RED eTap, RED, Force, Rival, Apex - Weight: 151 grams (11 – 25T), 185g (11 – 30T), 196g (11 – 32T) - Material High grade tool steel cog cluster, Heat treatment process, Heat treated aluminum lowest range cog, Elastomer rings - Speeds: 11 Gear Ratios: - 11 – 25T: 11,12,13,14,15,16,17,19,21,23,25 - 11 – 26T: 11,12,13,14,15,16,17,19,21,23,26 - 11 – 28T: 11,12,13,14,15,16,17,19,22,25,28 - 11 – 30T: 11,12,13,14,15,17,19,21,24,27,30 - 11 – 32T: 11,12,13,14,15,17,19,22,25,28,32

SRAM's E-BLOCK shifting technology is a fundamental redevelopment of external drivetrain shifting. On the E-BLOCK cassette, the chain has a defined link position on each cog. Cog architecture has been engineered to work with both inner and outer links of the chain, which allows extremely refined shifting for both inboard and outboard shifts. The result is precise and robust shifting performance in any situation, even with full motor support. - 11 – 48T, 8-speed cassette machined from case-hardened tool steel - Ideal mid-ship motor gear range - Increased chain wrap on climbing cogs - Symmetric shifting geometry allows fast, precise gear shifts - Optimal inboard and outboard shifting performance - The big steps between cassette cogs is a completely new cassette technology engineered specifically for the demands of E-MTB - Non XD driver body compatible - Gear Ratio: 11 – 48T - Recommended Group: EX1 - Cogs: 11, 13, 15, 18, 24, 32, 40, 48
