Right then chaps, I've fitted a Renthal Sr4 chainring and a ethirteen Lg1 chain device using a bb to Iscg05 adaptor ring, problem is in order for the chain ring to align with the jockey wheel on the chain device and not foul anywhere else on the device I've had to reverse the adaptor ring and use the thin shim washers and the original bb spacer, after about 4 hours of constant farting about and trying every conceivable combination, everything now works perfect exept that when I replace the non drive side crank arm it seems the axle comes through about 3mm short and therefore means the crank isn't sat fully home and also the black plastic splined plug that threads in is no longer long enough.
Has anyone had this problem before or know how to rectify it? Do I need a to buy a bigger bb?
Thanks in advance for any help.
Thank you...... much love
