I've acquired an early '90s Burley Zydeco and am trying, with some success, to identify the components. It has and eight-speed cluster on a Shimano freehub, but I can identify the cogs. More to the point of this thread, The crank is 170mm, but I can't identify the Manufacturer - something like Tra*cer. I can't make out the fourth character - need some help.
PS: it employs thumb-shifters; would like to know that supplier, too. The rest I have.
