RAPTOR – CS-M1150, 11 Vites Kaset Dişli, 11-50T, (HG), Spider Black, Black-Rainbow

The RAPTOR CS-M1150 Black-Rainbow is the 11-speed counterpart to the M1250 you viewed earlier. It is designed for riders using an 11-speed drivetrain who want a massive “climbing gear” (50T) without upgrading to 12-speed or changing their hub.

In the Turkish market, this is a popular “super-range” upgrade for bikes originally equipped with Shimano Deore M5100 or SRAM NX 11-speed systems.

## Technical Specifications

### Key Features

• Extreme Range (11-50T): Most standard 11-speed cassettes top out at 42T or 46T. The 50T “mega-cog” provides a significant advantage for steep technical climbs, effectively giving you a “bail-out” gear similar to modern 12-speed Eagle systems.

• HG Compatibility: It slides directly onto a standard splined freehub. You do not need a specialized Microspline or XD driver, saving you the cost of a new hub or wheelset.

• Rainbow Aesthetics: The large cogs feature a durable multi-color electroplated finish. It is highly resistant to chain wear and adds a high-end, custom look to the bike.

• Weight Management: By using a black aluminum spider to hold the largest cogs, the cassette remains relatively light for its size while protecting your freehub body from gouging.

### Compatibility & Setup Notes

1. Rear Derailleur: You must use an 11-speed rear derailleur with a long cage (SGS).

   • Shimano: Compatible with Deore M5100-SGS. Older M8000 (XT) or M7000 (SLX) may require a “GoatLink” or derailleur extender to clear the 50T cog comfortably.

   • SRAM: Compatible with NX/GX 11-speed long-cage derailleurs.

2. Chain Length: Because of the jump to 50T, you will almost certainly need a longer chain (usually 116 or 118 links) than what was used with a standard 11-42T cassette.

3. B-Gap Adjustment: Proper adjustment of the B-tension screw is critical for this cassette to ensure the upper pulley wheel doesn’t hit the 50T cog during shifts.

Comparison Tip: Compared to the Shimano Deore CS-M5100 (11-51T), the Raptor is lighter (due to the aluminum spider) and offers the unique Rainbow finish, whereas the Shimano is typically all-steel and finished in basic silver/grey.
