Hi mate,
erm - have a question. I am searching for a spider for my tune bigfoot cranks - got them without the spider.
Now I see Your cbr spider and in case that they are similar to the tune cranks, could You confirm a few measurements?
ID of the big center-hole? ID of the threaded big nut? ID of the secure-hole, through which a little bolt goes into the crank arm? And the distance of the 2 holes?
Or another idea, what would be easier:
lay the 2 parts (the spider and the threaded ring) on a piece of paper. Outline all holes and thingies with a pencil, scan the paper and mail it to me
