Just picked up a his and hers (like a Mixte!) Marin, Madrone Trail, bike. designed by Joe Murry,84/85 Nat,l Champion, made in Taiwan. It has the longest wheel base I have ever seen. Kinda looks like a chopper! The men's was way to big for me, so the other one gets the good stuff treatment, like alloy wheels,DNB climber shifters and F&R derailleurrs, brake set up is all Lee Chi, using braze on attachments. Don't know what size the rims are, 26 " I think. 26 x 1 3/8. Oh, 18-speed! also have a suntour av tech front and shimano sis rear derailleurs. Don't know which is the better set up. Any and all comments are welcome.
