The Micro Racer Tubeless Tire Repair Kit packs Dynaplug's Twin Tube technology into the smallest aluminum tool in the line, loading two plugs into a single tube under an O-ring-secured cap for the fastest deployment they make. At 15 grams loaded, it adds almost nothing to a saddle bag or jersey pocket, but the second plug means a first puncture doesn't leave a rider without a backup for a second one. What Our Gearhead(R) Experts Are Saying:"I flatted twice on the same ride, which never happens, and the second plug was already sitting there ready to go. I didn't have to dig through a pack for a spare or turn the ride around."
