I'm assuming you are referring to 700c? Tough call...I know that the 29" quadangles ran those hubs...but they would have noticeably wider rims. The early pk ripper fixies, may have ran these hubs. Most of the 700c se bikes ran low flange hubs without cutouts...but, there is a lot of different models over many years with 700c wheels in the time frame of those hubs that they may have used them on. I've seen them mostly on the retro 20" PK Rippers, 26" OM flyers, & 29" quadangles, however.
