SRAM’s latest 12-speed eTap AXS road and MTB groupsets can be used together, setting up the option for ‘mullet builds’, which pair up road shifters with an Eagle AXS rear derailleur and a 10-50 cassette, for an ultra-wide gravel bike build.

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. 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.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.

The current 12-speed generation of Shimano electronic groupsets have inter-compatible wiring and electronics and use the newer SD300 wire variant. 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 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 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.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 With clutch derailleurs offering a quieter and more reliable drivetrain, there are few compelling reasons not to buy a clutch derailleur for a mountain bike. What do I get with a more expensive derailleur?

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. Current 9-speed Shimano mountain bike components are compatible with older 9-speed road and mountain bike components, excluding the aforementioned exception 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. Now that we’ve gone through the tortuous process of working out exactly what will work with your drivetrain, you have the fun of deciding which price point to go for. 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

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 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). 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 The good news is there’s some reverse compatibility between version three 11-speed EPS components and older generations.
