## Overview

The Shimano SLX RD-M7100 Rear Derailleur is a high-performance, 12-speed mechanical drivetrain component crafted from durable aluminum. Featuring a long cage design with a 51-tooth cassette capacity and Shadow Plus chain stabilizer, it delivers precise shifting and enhanced chain management for demanding mountain biking conditions. Engineered for riders seeking reliable, mid-range tech with trickle-down innovations from Shimano’s top-tier groupsets.

## Description

SLX drivetrains seem to be an afterthought. We get it -- XT and XTR are flashy and featherweight, but when it comes to workhorse components, SLX is damn near impossible to beat. Thankfully, it also comes along with trickle-down technology from its pricier siblings, and it's easy to see with the new SLX RD-M7100 Rear Derailleur that's optimized with 12-speed technology, crisp shifting, and sleek graphics that elevate standards far above what we think of when we talk about mid-range groupsets. It comes ready to take on the big-guns, with a 51-tooth capacity (a whopping 10 extra teeth above the previous version), and the flexibility to run both of Shimano's 12-speed cassette offerings. The new SLX rear derailleur features a larger, 13-tooth pully wheel for an increase in efficiency and chain management while you're riding. This partners up with advance shifting performance to deliver decreased tension when you're in the big rings. More changes happened to the pulley cage, with an added bumper that protects your pulley wheel from impacts with rocks and branches -- an appreciated feature with the extra length that the derailleur hosts in order to accommodate all 12 cogs. The derailleur is built to accommodate both of Shimano's new 12-speed cassettes, the 10-51t, or 10-45t cassttes, so you can find the right gearing for your ride, regardless of you're charging full-speed through smooth ribbons of single track, or crunching up steep, seemingly endless fire roads on sky-high enduro climbs. One thing that we're thankful has stayed the same through the generations is the stabilizer switch that we saw trickling down from XT and XTR in the previous model. When engaged, this switch helps to eliminate chain slap and dropped chains by increasing spring tension. This is a valuable option for suspension systems that require chainstays and pivots located close to the rear derailleur. The RD M7100 keeps a good thing going with some of the previous model's improvements, including th...

Review: Confiable, a buen precio, resistente, SLX es para mi la mejor opción de shimano
Review: Non il modello di punta di Shimano, ma se volete rimpiangere meno un eventuale incontro con una grossa pietra, come è successo a me, questo ha un prezzo accessibile. Il funzionamento è preciso anche sotto sforzo. giusto equilibrio qualità prezzo

## Questions & Answers

**Q: Is this the 51t max cog version?**
A: Mine worked fine with the 51t cassette.

**Q: Will this work with a Sram Eagle 12-speed cassette?**
A: Yes. I have used mine with a SRAM 12 speed cassette for the past 1.5 years. Works very well.

**Q: Work  for 2022 poligon sisuk T8?**
A: I have a 2021 but I don’t think there are any differences. That said, yes, it did work for me. I also had a bent hanger, so I had to address that as well.

**Q: Is it clutched?**
A: The clutch is the worst part.  It requires service about once a month.  If you bought this already, and if you see your chain go slack on a ride, turn off the clutch, and it works as a non-clutch derailleur.  Good enough to limp home, but you will suffer chain slaps and maybe chain drops.
