Kenda Part Number: 05197420T

🚨  You Ride Hard. Your Rear Tube Should Too.

You're putting serious power down—but your rear tube can’t keep up. Whether it’s harsh landings, rocky climbs, or long-distance rides, standard tubes just aren’t built for that kind of abuse. A blowout mid-ride? Game over.

 ✅ Meet the Tube That’s as Tough as You Ride

The Kenda Tuff Tube 110/90–120/90-19 is engineered for heavy loads, high torque, and unforgiving terrain. With reinforced butyl rubber and a heavy-duty TR-6 valve stem, it’s the rear inner tube serious riders trust to stay inflated and perform under pressure.

❌  What Happens If You Don’t Upgrade

Stick with stock or cheap tubes and you’re rolling the dice. Blowouts on the rear tyre—especially at speed—can lead to major bike damage or worse. Don’t let one weak link ruin your ride (or your rim).

✅  What Happens When You Do

With the Kenda Tuff Tube, you’re protected. Ride faster, hit harder, and lean in deeper knowing your rear end is reinforced with serious puncture resistance. Less time fixing, more time shredding.
