SHIMANO DEORE XT RD-M8100 SGS Outer Cage Plate

Restore the flawless shifting performance of your high-performance mountain bike with the genuine SHIMANO RD-M8100 SGS Outer Cage Plate. This essential spare part is specifically engineered to replace a damaged or bent outer plate on your DEORE XT 12-speed rear derailleur, bringing it back to factory-spec precision. Don´t let a rock strike or crash compromise your ride; this cost-effective repair solution ensures you can get back to tackling demanding trails with the confidence and reliability you expect from SHIMANO. By replacing just the damaged component, you save money over a full derailleur replacement while maintaining the integrity and performance of your entire drivetrain.

This outer cage plate is a critical component for the smooth operation of your transmission. It is designed to perfectly house the 13-tooth pulley wheels of the RD-M8100 derailleur, ensuring optimal chain wrap and tension across the entire 10-51T cassette range. A straight and true cage is paramount for the crisp, rapid shifting ação of HYPERGLIDE+ technology, allowing the chain to move up and down the cassette seamlessly under load. Restore the quiet, stable, and efficient drivetrain performance that the DEORE XT M8100 series is renowned for.

Key Benefits:

* Restore Peak Performance: Bring your RD-M8100-SGS rear derailleur back to its original, out-of-the-box shifting accuracy and chain stability.
* Cost-Effective Repair: A smart and economical alternative to replacing the entire derailleur assembly after damage from trail impacts.
* Genuine SHIMANO Quality: As an original SHIMANO spare part, it guarantees perfect compatibility, fit, and function, preserving your bike´s performance and value.
* Maintain Drivetrain Integrity: Ensures correct alignment for the pulley wheels, which is crucial for the low-profile SHADOW RD+ design and the precise chain engagement of HYPERGLIDE+.
* Easy Installation: Designed for a direct fit, allowing for a straightforward replacement to get you back on the trail quickly.

Main Features:

* SGS Super Long Cage Design: Specifically engineered for the wide-range gearing of SHIMANO 1x12-speed drivetrains, particularly the 10-51T cassette.
* Optimized for 13T Pulleys: Precisely manufactured to accommodate the larger 13-tooth guide and tension pulleys, which increase shifting efficiency and reduce friction.
* SHADOW RD+ Integration: Forms an integral part of the low-profile derailleur design, which tucks the derailleur inboard to protect it from rocks, roots, and other trail hazards.
* Precision Manufacturing: Built to SHIMANO´s exacting standards for perfect alignment, ensuring crisp and reliable gear changes on every ride.

What our customers are saying about Shimano RD-M8100 SGS outer cage plate

This genuine Shimano RD-M8100 SGS outer cage is a perfect-fit replacement part for Deore XT 12-speed rear derailleurs. It´s an excellent value for repairing a bent or broken cage after a crash. Made from tough aluminum, many find it more durable than the stock carbon XTR version, and it is compatible with XTR M9100 derailleurs. This original part (Y3FX98050) is easy to install and works with 10-51T cassettes. A key feature is the built-in rubber bumper that effectively reduces chain noise and slap for a quieter ride. It includes the necessary stop captive and washer

XT gearbox. In case of a crash, if the rest of the gearbox is not broken, it is worth buying this and not replacing the whole gearbox. It includes the captive that acts as a stop and the washer that goes inside. The only thing is that you have to be a bit handy to remove the clutch.

Shimano GRX RX822 12s from 45 to 51 teeth

2024/10/12

juan-carlos

Would it be useful to convert the Shimano GRX RX822 12s from a 45-tooth sprocket to a 51-tooth sprocket? Thanks and regards

Answer of Leonardo

Usually it is possible but you need to check the length of the chain

Compatible con XTR M9100 SGS

Daniel

Hello, I would like to know if it is compatible with the XTR M9100 SGS model. I think I appreciate that the only thing that differs is the material from which one is made of aluminum and the other is made of carbon.

Answer of DAVID

Hello, yes it is compatible with the xtr 9100, you just need to change the stop screw (take the xtr to put it on the xt yoke, they do not have the same length)

OUTER ARM

2023/09/16

Alessandro

Good morning. I need to replace the outer arm of a mechanical Shimano XT 12v (I think it´s the M8100 model). The product code indicated by the manufacturer is Y3FX98050. Is it correct to purchase this item? Thank you.

Answer of Goncalo

Fits all 12-speed Shimano derailleurs, Deore, SLX, XT. The reference you are indicating is this: https://www.tradeinn.com/bikeinn/es/shimano-rd-m8120-external/137974355/p Best regards!

Do they include the external and internal part of the box?

2023/04/25

Aritz

Hello, I wanted to know if both the external and the internal pulley come, thank you very much.

Answer of Andrzej

This offer is only the outer arm to which the chain rollers are screwed. It´s not a set. However, it fits the M8100 and M7100
