Introducing the all-new 2020 Crupi OS20 (Over Size 20″) Race Frame! The wheel size of this bike is the same diameter as 20 x 1-1/8″ or 20 x 1-3/8″ wheels making them bigger around but then they are wider and stronger like Pro rims are. This makes the bike feel a little more stable and is still considered a 20″ bike!
OS20 frames are custom made to order so you can choose a Standard 1-1/8″ or a Taper head tube to meet your needs. This all American made frame is constructed of high-grade 6061-T6 Aluminum and features a butted top and down tube. Please allow roughly 8 weeks for production.
