ISCG 05 Blackspire Stinger

For sale is my ISCG05 Blackspire stinger. I bought it to fit to my Titus El Guapo and it didn't fit as the plate is too thick. So I took it to a local machine shop and had about 1.5mm machined off the back plate and it fitted fine using the smaller nut and bolts through the ISCG bolt holes (the iscg bolts still fouled the inner chainring). This setup ran without a problem for 10 months without rotating and doing a great job of keeping the chain one. The bearing in the roller is still great and the whole thing is in good condition.£12 posted for the set.
