Just got a new bike (SB 130), and have been looking into carry on bike tools.
Many people know about the ONEUP, but i have found a couple of others that look interesting...2 that go inside your Bar, and one that is part of the Thru Axel
@Mcfein2002 the matchstix is hella expensicve. The OneUp is my personal favorite as it lives in your steer tube. another option is the giant clutch system (crank one) or the granite stash which also goes in your cranks. bar end ones are great but they only work with certain grips.
