The Mattone Ultimate Flat Kit builds in a backup for the one thing that can end a ride: a broken lever mid-repair. The Eolo Levers Premio's reinforced nylon coating and integrated CO2 regulator make it the primary tool for carbon rims, while the standard Tire Levers Premio ride along in the same Mattone Seat Pack as a second pair if the first one snaps. The Italian Army Knife and Elettrico Ultimate Mini Inflator round out the kit with small-fix tools and a digital gauge for dialing pressure back in. What Our Gearhead(R) Experts Are Saying:"I run carbon wheels and I've snapped a lever mid-repair before, so having the Eolo Levers as my primary tool and the standard Tire Levers Premio as backup in the same pack means one bad lever doesn't turn into a long walk home."
