    2x10 Superlight 29er Which Rear Derailleur

    Ok so we ordered my wife a Superlight 29er in a RXC29 build we are making it a 2x10 and just taking off the big ring and installing a bashguard and limiting the front derailleur.

    I want to replace the rear derailleur with a midcage but not sure which one will be best on the Superlight, its Shimano and there are so many XT rear derailleur's to choose from. I have to be honest I don't have a clue what any of the diff numbers mean ie 780, 781, 786? I know GS is midcage and I think we want the clutch type to elminate some chain slap.

    Thanks

    I believe to get the full benefit, you'll need the 786 shadow plus. BlueSkyCycling.com - Shimano Deore XT RD-M786 Shadow Plus Rear Derailleur 10 Speed


    I did this on my old RXc 29er but did not change the derailleur.

    Yeah the 786 is probably what we will go with.
