SHIMANO RD-M592 Deore Shadow rear derailleur, black

Product Information

All 11-speed Shimano road components are inter-compatible – you could use a Dura-Ace R9100 derailleur with a pair of 105 R7000 shifters. This is also true of the brand’s 11-speed GRX components Although SRAM, Shimano and Campagnolo’s interpretations of a clutch derailleur differ slightly, they all aim to achieve the same thing. Apart from first-generation Dura-Ace Di2, which uses a different wiring harness, the second (11-speed) generations are inter-compatible, across road, gravel and mountain bike groupsets as they all use the SD50 wires and share the same electronics. and 9-speed SRAM components are all inter-compatible, regardless of whether they are road or mountain bike parts

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.

Returns

A clutch derailleur essentially increases the resistance this pivot provides – either through a clutch or more complex electro-hydraulic systems, as seen on SRAM AXS – resisting fore and aft movement of the derailleur cage, and making for a far quieter and more reliable drivetrain. You should always keep proof of postage and we advise you to use a ‘signed for service’ when returning goods. The granting of a best price is not combinable with other promotions (e.g. "free articles) from Bike-Discount. 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 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.

All 11-speed Shimano Di2 road, gravel and mountain bike Di2 components are inter-compatible – you could, for example, use an XT M8050 rear derailleur with a pair of Ultegra R8070 shifters The situation is a little more clear with SRAM and we’ve summarised the main points below. SRAM road and gravel derailleur compatibility SRAM’s current 12-speed eTap AXS rear derailleurs are all compatible across road, gravel and mountain biking. For example, you can run an Eagle rear derailleur on a road or gravel bike. If you’re doing this, you’ll need to run a compatible chain (you cannot run a road FlatTop chain with an Eagle rear derailleur), chainring and cassette Top normal spring uses the spring to select higher gears, best suited to use with Rapidfire shiftersWhile the derailleurs will work, chainlines differ between GRX, Shimano’s road groupsets and its mountain bike groupsets. For clarity, 10-, 11- and 12-speed Shimano road/gravel and mountain bike components are not inter-compatible with each other. This is because they use different cable pull ratios Current 9-speed Shimano mountain bike components are compatible with older 9-speed road and mountain bike components, excluding the aforementioned exception

Shimano’s latest XT Di2 M8150 12-speed rear derailleurs are designed for electric mountain bikes and are not compatible with non-assisted bikes All 12-speed Shimano mountain bike components are inter-compatible – you could, for example, use an SLX M7120 derailleur with an XTR M9100 trigger shifter 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.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 speed road components (except and 10-speed GRX gravel and Tiagra 4700 – notes below) are inter-compatible. You could, for example, use an old Ultegra 6700 derailleur with old 105 5700 shifters 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.
