    XX rear derailleur tension

    Hey there,

    I have noticed that my rear derailler is losing tension and when Im going through roots and rocks, it starts moving forward pretty easilly and have had the chain coming out of the front ring with more frequency, specially when Im using the smaller ring.

    Any way to adjust this tension? or should I replace the spring coil?

    Would appreciate any input on this issue

    Thanks!

    Take a look at the rear derailleur and make sure you B-tension screw hasn't rattled itself loose. Tightening that B-tension screw will help; unfortunately, this will come at the expense of crisp shifting performance. Proper B-tension screw adjustment leaves approximately 5mm between the guide pulley and the largest cog on the rear cassette; tightening this screw will increase the distance between the guide pulley and the cassette, thus worsening shifting performance. Experiment with turning the B-tension screw to see if it improves the problem. The other option is to remember to shift into the middle or large ring up front when going through rough terrain.

    Go on ahead, I'm gonna take a breather.
