So just stepped up to this bike from a 2011 Airborne Spectre 26" . I am wanting to do a couple things right off the bat and have some questions . Hoping to possibly change the tires and go with a tubless setup for weight savings but not sure of the manufacturer of either the rims or tires that come on this bike . Googled the part numbers but just keep finding adds for the bike itself . The rims are DH-18 32h and the tires are H-5120 29 x 2.1 . Any ideas on the manufacture of these ?
