    NRS 1 problems?

    My bike makes this weird metallic grinding sound by the front sprocket, not sure if its internal or external(chain) and it also jumps out of gear. Any one else encounter this?( sorry for the vague description but its the best i could do)

    bottom bracket?

    i would try and shoot some lubricant into the bottom bracket area to see if that helps, as well as on the chain. If you dont know what it is after that, I would take it in to LBS.
