Details

• [Wide Drivetrain Fit] This 12 speed mountain bike cassette works with M6100, M7100, and M9100 12 speed drivetrain setups. A practical replacement for trail riders and home mechanics, it supports a clean gear range for climbs, descents, and everyday route changes.
• [Hollow CNC Structure] The hollow CNC design reduces rotating mass compared with solid construction, helping riders feel more responsive handling on climbs and technical trails. A useful choice for mountain cyclists who want a focused, agile setup without adding unnecessary bulk.

• [Service Friendly Setup] Designed for straightforward installation and removal, this cassette supports quick replacements, routine drivetrain care, and bike customization. It suits cyclists who maintain their own bikes at home or prepare a trail setup before a weekend ride.
• [Aluminum Alloy and Steel] The cassette combines aluminum alloy and steel components for a balanced structure during repeated riding and gear changes. Suitable for mountain and road cyclists, it supports regular use through commuting, training, and rugged outdoor routes.
