Tubliss Bladder - 18in. IB18

I've been using Tubliss since late 2017, both front and rear. Several tires changes in that time. I'm only a weekend warrior type rider, not aggressive and not a racer and I only rides woods trails in the northeast. Some road connectors too. The system has worked fine, and only the high pressure bladder will lose some air over a week or more of sitting. The low pressure side never loses air. Recently, I was on the last couple miles of trail end of ride and something felt wonky with the front end. After getting home, I discovered the front tire was flat. Huh... After pulling the front tire off (needed a new one anyway for an upcoming event) I found the bladder had a small tear near the base of the high pressure stem. Don't even know how that was possible. Maybe a rock got it on a hard hit that compressed all they way through the tire and liner?? Really unsure. Bought two new bladders, just finished installing. Hope to get another 5+ years out of the system. The liners are a bit dinged by tire irons, but since they continue to seal, so I'll keep using them.

Great product. Tubliss service is second to none.

The best mod you can do if you run in rocky terrain

Popped 2 inner bladders installing myself. Watched all the videos and followed the instructions to the T. 3rd time had the shop do it and they're fine. Otherwise very happy with the improvement.
