i'm generally a fan of the cinelli stem aesthetic. i recently got (what i consider to be a great deal on) a cinelli stem. as far as i can tell, it's a 1/a, but with a 26.0 mm clamp. the new cinelli logo is stamped on the top, and i think the finish is gorgeous. it was listed as used, but i couldn't find any evidence that it was mounted or that bars were installed in it. i think i paid like $20 shipped...
