Hi there today i was just cleaning my bike and inspecting everything for cracks as you do and i managed to find one on my left crank arm so i would like to know where i stand, i looked on the middleburn website and it says that the cranks have a LIFETIME warranty against defects in materials or workmanship*, covers competitive DH, TRIALS and jumping! my cranks are middleburn RS7s
before i call them up would those of you who have had experience with middleburn be able to spare 2 minutes of your time and tell me about middlburns warrenty procedure and guide me through what i will have to do to get my cranks replaced bearing in mind that the cranks are second hand and fairly scratched up.
any help would be great all the tapers and threads are fine
P.S i appolegise for any spelling or punctuation mistakes
EDIT: my crank arms are sqaure taper and are 165mm long, would they let me have replacements in ISIS taper and 170mm long
