Introducing the 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 considerd a 20" bike!
OS20 frames are custom made to order so you can choose a Standard 1-1/8" or a Taper head tube and choose to have brake posts or no brake posts 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.
