    Upset 12 speed Ethirteen kit


    Just got a Ethirteen kit converting my 11 SRAM speed set up to a 12 speed 9-46 cassette .
    Installation went fine its shifting ok but I have a REALLY LOUD GRINDING noise . Sounds like a rusty/stretched chain noise ..????
    I put my wheel on my friend s bike and its fine so I know its not my bearings, wheel, cassette .

    I adjusted my derailleur and lubed it , lubed the chain, jockey wheels... its shifting ok , yet loud grinding noise I even used a B screw tool ..nothing seem to get rid of that grinding

    Anyone had similar problem ?

    What chain and chainring are you using? Did you size the chain properly? You have to mod the derailleur cage correct? Are you sure you did that correctly?

    A new chain on a worn aluminum ring can sound/feel like what you're describing. I switched to steel rings for this reason. Smooth and quiet.
    What, me worry?

    Sorry capital letter my keyboard is messed up

    worst part is that im pretty knowledgeable in mechanic especially mtb but i failed to see right away that the chain ring was bad . However it didnt look that bad at all . I took the rear wheel apart regreased all the bearings , adjusted the derailleur, ........the whole enchilada its . Tried to contact ethirteen (still waiting for them to reply back :{{{{{{ }
    2 days later i had it and borrowed a front chain ring which is actually bigger than my old one ...and no more noise ha ha ha the funny thing is that now im back to square one concerning the gear ratio ha ha ha ha but i just bought on ebay another small front ring ...btw my set up is 9-46 and not 10-50 because im doing well up hill and felt that 10-50 was cheating :}}}}
