    blackspire stinger on parker

    I have an 08 parker frame and I am installing a Blackspire Stinger (icsg05 mount). The problem I have is that when I tighten the crank the small chain ring makes contact with the the BS stinger before the crank is fully tightened.

    The crank is a RF evolve DH 24/36/bash and the spacers are set for a 73mm bottom bracket with a 48mm chainline.

    Is the bottom bracket for the parker 73mm or 68mm? I measured 73mm(lengthwise along the bottom bracket shell), but jensonusa has it listed as 68mm so I wonder if that may be my problem.

    I changed my crank setup from 73mm bb to 68mm. That helped a lot but the chain was still making contact with the BS stinger. I used my dremil and cut/trimmed the stinger to get the needed clearance. All is well now and the stinger works quite well.
