TIRES: We hope you're already running tubeless wheels, which eliminate pinch flats. If not, get some tubeless rims, then wrap them with a pair of Hutchinson Toros ($60 each; hutchinsontires.com), which have reinforced sidewalls that resist cuts and a slightly raised tread pattern that's ideal for Moab. Inflate them for the first time with the company's Fast'Air ($14), which has a latex mixture that will plug any punctures.
LIGHTS: The low angle of Light & Motion's handlebar-mounted 700 ($550; bikelights.com) will cast shadows to give you contrast and depth, while their Stella 150 L ($230) on your helmet will let you look through turns and past obstacles. The batteries have enough juice for two nighttime laps on the high setting (think car-headlight bright).
HYDRATION PACK: You'll be out for no more than two hours at a time, so a smaller pack, like CamelBak's Octane XCT ($70; camelbak.com), is ideal.
REPAIR KIT: Bontrager's Rollbar 18 ($50; bontrager.com) has everything you need for simple trailside fixes (hex wrenches, brake-pad spreader, chain tool), but not blown tires; for that, you'll want their Air Pack flat-repair kit ($40), which includes CO2 cartridges, inflator, tire levers, and patch kit in a padded pouch.
