Dura Ace tubular front wheel. 50mm deep. This is a brand new rim built onto a used hub. The rim was damaged years ago and replaced by insurance. then got put in the shed and never used. Braking surface absolutely unmarked, slight glue residue on the rim bed from stretching a used cross tub on it. This will easily clean off with some white spirit. Hub is buttery smooth. Comes with Shimano wheel bag and genuine Dura Ace QR. Slightly peeling decal will glue back down easily.
