This is a pair of vintage Sugino AT crank arms, their flagship model. These arms 170 mm in length, the bolt circle diameters are 74 and 110 . These arms came from my “good stuff saved for later” bin, which I am thinning out. They are in really really nice condition, with just a few marks from use. Included are new old stock bolts and spacers for mounting the little ring. I have uploaded large photos. Please take a look. Thanks!
