Ground control to…Velocity’s cyclocross specific tubular. Have this rim handbuilt with any number of hubs by MLW for the upcoming cross season. The Major Tom’s 23mm wide profile is geared specifically toward cyclocross. Unlike narrow tubular road rims the Major Tom allows a wider cross tire to have a more natural profile. The wider rim also features a wider gluing surface and a seam relief channel which allows for consistent and reliable tubular tire installation.
