SHIMANO RD-M592 Deore Shadow rear derailleur, black

Product Information

Campagnolo’s Super Record EPS electronic groupset is now onto its fourth generation. Matthew Loveridge / Immediate Media While the derailleurs will work, chainlines differ between GRX, Shimano’s road groupsets and its mountain bike groupsets. The only exception for 9-speed groupsets is pre-1997 Dura-Ace gearing, which won’t play nicely with anything because it uses a totally different cable pull ratio This is also the case with Shimano’s 11-speed mountain bike components – for example, you could use an XTR M9000 derailleur with a pair of SLX M7000 shifters speed SRAM components are inter-compatible, regardless of whether they are road or mountain bike parts – for example, you could run road shifters with a mountain bike rear derailleur

Compatible parts are now marked by a letter surrounded by a square box – simply put, if all of your components have the same stamped letter on them, they’ll work together. Almost all modern mountain bike derailleurs (and Shimano’s GRX gravel groupsets, Ultegra RX rear derailleur, Campagnolo Ekar, SRAM’s single-ring road groupsets and eTap AXS 12-speed road rear derailleurs) include a clutch mechanism. Most* 8- and 9-speed Shimano mountain bike and road kit is inter-compatible because they both use the same cable pull ratio. This means you can use an 8- or 9-speed mountain bike derailleur with road shifters, or vice versa The main difference you’ll find between road bike and MBT derailleur is the length of the rear derailleur component. Mountain bikes have lower and wider spaced gears usually and this means the rear derailleur needs to be able to handle a bigger span in change length than standard road bike derailleur Bike Derailleurs at Decathlon The current 12-speed generation of Shimano electronic groupsets have inter-compatible wiring and electronics and use the newer SD300 wire variant.The Shimano Deore XT SGS M771 Rear Mech delivers reliable and precise shifting with a stiff All-alloy and lightweight construction without compromising strength and durability. Regular rear derailleurs rely solely on the tension provided by the main pivot to keep the chain in place.

Dura-Ace 7970 and Ultegra 6770 Di2 10-speed components are not compatible with each other. This is because they use different wires, with the Ultegra variant using the SD50 type that would go onto be used on 11-speed.

Clutch-equipped rear derailleurs were once the sole preserve of mountain bike offerings, but are now seen on both gravel and road groupsets from Shimano and SRAM. Matthew Loveridge / Immediate Media There are two common situations where there may be a large range, or spread, of gears on your bike – when using a super-wide range cassette (eg, 10-42t or larger) or when there is a large difference between chainring sizes (eg, when using a triple chainset). The good news is there’s some reverse compatibility between version three 11-speed EPS components and older generations. What cage length derailleur should I buy? There are also differences in the pull ratios used between different groupsets: the Ergopower shifters used by mechanical Super Record, Record and Chorus 11-speed are not compatible with Potenza, which itself is incompatible with both Ergopower and Centaur Power-Shift systems. Campagnolo has introduced many changes to its groupsets, resulting in reduced compatibility between generations. So boxed letters (indicating the ranges) will aid you in identifying if your parts are compatible. CampagnoloCampagnolo’s Super Record EPS electronic groupset is on version four now and has gone 12-speed. Again, it’s a system unto itself, with its own electronics to communicate between the shifters and the rear derailleur. If you find an item at a lower price with another commercial internet retailer, you will receive it from us at the same price, provided the conditions listed in the link are met. Campagnolo provides a much more thorough description of the changes and we highly recommend you read through this guide carefully before committing to any new parts from the Italian marque. But now things get more complicated (or simple, depending on which way you look at it) with slight tweaks to all of Campagnolo’s groupsets resulting in reduced inter-compatibility between groupsets. Now we’ve determined the speed, brand and compatibility of your derailleur, you must work out the cage length that your drivetrain requires: long, short or medium.
