just wondering what the slight differences were. the arms look the same, so I guess must be purely the spider?

from what i read so far the only difference is the bolt that fixes the spider to the crank. in the following post
http://www.mtb-news.de/forum/showpost.p ... stcount=15
the poster states that the grafton cranks used a normal allen key screw and the topline/pbc cranks a ti bolt with rounded head.

From what pictures i can find of the grafton cranks, i'd say it is with about 90% certainty a topline, the crank arms look exactly like tose of topline (spider looks more like a grafton or cooks bros, dont know if these are compatible)

found the following on the mombat site:
http://mombat.org/Grafton.htm
http://mombat.org/Topline.htm
i conclude that the first grafton cranks produced by topline were called "speed sticks". they were produced in 1991. in 1992 grafton seems to have released a new crank design, the "joystix".
topline released their cranks in 1992.

If anybody is interested i'd be willing to part with the crank, comes with all the parts shown on the previous page. Price will be reasonable (what i paid for it).
PM me.
