Bought off ebay, poorly listed, brushed with sandpaper. Just polished a little bit. Looks CNC machined to me, light too (450 gram shown on post scale) Two piece drive arm. 110 BCD. Never seen these before. I cant find any informations about it. Checked all GT catalogues, internet and nothing. Cranks shown in catalogues looks different. Thought they may be some odd downhill versions, but granny ring could be installed so they're not. Any thoughts?

Saw these too on the bay. Was tempted myself for the RTS!

Dont know anything about them, other than they are very nice.

Give member gm1230126 (or whatever the numbers are!) a PM about them.

Pretty sure those were made by Profile Racing about the same time GT was private labeling the Profile race chromo arms.

We had a profile Sponsorhship around the same time, and I seem to recall my aluminum profiles looking exactly like that.

Radoslaw I don't mean to hijack your thread but I just picked up these NOS arms too and they are amazing and probably very old prototypes. I got them from a former GT So Cal. employee. They are probably 88-92 vintage as they have the original early 3 mountain logo. Funny thing is the original spider is 130mm BCD which would make it usable for bigger downhill gears or BMX. I messaged Profile to see if they have or can make a 110/74mm spider to fit. If I wind up using them as is I will probably put them on my SS Psyclone. These were never cataloged or sold to the public. The are heavily machined in the middle of the arm on both the front and back sides and maybe 3/16" think through that part of the arm. Very light.
