IRC - Heavy Duty Tube 12"

Stock tubes are fine until they're not, and out on the trail, a flat is the last thing you want. Two to three times thicker than standard tubes, IRC heavy duty tubes are incredibly durable, abrasion-resistant, and feature great impact absorption. Made 3mm thick and puncture resistant, and constructed from a blend of both natural and butyl rubber, these fit both the front and rear 12" wheel positions so one tube covers the whole bike. High quality Japanese tubes meet or exceed OEM quality standards, reliability you can count on every ride.
