    Drivetrain locking up

    I am currently riding a heckler with a shimano xt drivetrain. Whenever I seem to really go hard especially on the uphills the drivetrain locks up. It seems like something gets stuck near the rear derailleur and the whole drivetrain completely locks up. If I pedal backwards it will release. Any Idea as to what may be causing it?

    but maybe a couple things to check. Look at the chain closely. See if all the links are flexible and the pins aren't sticking out anywhere. Also, check the pullies on the derailleur. You'll have to pull bolts on cage to get chain out of way. Make sure they are spinning smoothly. Last and most obvious is the wheel. Pull it and make sure everything is spinning smoothly.

    Next time it happens look down and your chain is probably still hooked into whatever chainring your in, really sucks. Might need a good cleaning and lube
