What is it?

The Nuetech Tubliss tire system is a dual pressure chamber system that replaces conventional inner tubes and rim locks. Nuetech claims their Tubliss system allows a rider to run lower pressures, improves traction, is lighter than HD tubes, makes pinch flats a thing of the past, protects the rim better, and lasts longer than conventional tubes.

First Impressions

The front and rear Tubliss tire systems came neatly packaged and ready for installation. Each system included a high pressure bladder, tire liner, integral rim lock, rim plugs, rim tape, installation tool, and instructions - everything necessary for mounting. Overall, the Tubliss system felt and looked like a robust product.

The Setup
The Nuetech team advised that I would need new tires in order for the Tubliss system to work properly. The reason for this is because conventional rim locks leave indentations in the tire’s bead that make it impossible for the Tubliss system to function correctly. I leveraged the Nuetech team’s experience with their product and put traction’s fate in their hands. I shared with them that hare scramble racing in Southeastern Wisconsin brings a wide variety of terrain including sand, mud, rocks, roots, and occasionally nice tractable dirt. They set me up accordingly with the following tires.

Front:  Shinko 546 90/100 - 21

Rear: Shinko 505 Cheater 110/100 - 18

I was informed that tire selection is critical for successful implementation of the Tubliss system. When running lower tire pressures the stiffness of the sidewall plays a huge role in how the tire behaves, which makes or breaks the riding experience and, in some cases, the durability of the Tubliss system.  

Using a tire sealant, such as Slime, is optional but I did opt to do so when I mounted my tires.

Installation
Installation of the Tubliss system is significantly different than that of a regular tube, rim lock, and tire. Fortunately, a comprehensive set of instructions are supplied which include detailed pictures and references to online videos. The installation process consists of approximately 7 well outlined steps which are not overly difficult to execute. Viewing the online videos was incredibly helpful and made the supplied printed instructions feel more supplemental than essential.

A handful of tools/lubricants were required to mount the tires which included:

  • 7/16 drill bit (used to make a hole in the rim for the additional valve stem)
  • Armor-All tire shine
  • Dish soap and/or tire sealant
  • tire irons
  • 120 psi capable air source

Overall, I did not find mounting the tires with the Tubliss system installed any more challenging than a conventional setup. In terms of time, I spent a short afternoon removing my old tires, inspecting the condition of my rims, and implementing the Tubliss system.

In Action

Prior to installing the Tubliss system I had three races under my belt in this year’s hare scramble season which allowed me to have a sort of benchmark using a conventional setup. With the Tubliss system installed I participated in six races and numerous practice sessions, logging a total of over 20 hours with the system installed. Due to Nuetech’s claims about the many advantages of the Tubliss system I wanted to put ample time on the Tubliss system and new tires prior to reporting so that I could feel confident in assessing both performance and durability.

Traction and Tire Pressures
Soil types and conditions varied throughout the race season. Many of this year’s events were either partly or completely wet and soils ranged from dry sand to muddy clay. One could not ask for a more broad spectrum of conditions to test a new set of tires in.

With conventional tubes I normally ran around 10 - 12 psi tire pressure. Right from the start I halved those values and experimented in the 4 - 7 psi range for both the front and rear tires. In general, I felt the tires responded well to reductions in pressure.

While traction is difficult to quantify, one of the most memorable parts of the racing season this year were the starts of all the races, and in particular, my first race with the Shinkos and Tubliss system installed. To put things in perspective I’m a mid-pack finishing B-class racer, however, I consistently was in the top five when it came to position after the start of the race. While there are many factors that dictate how good of a start a rider gets, I do believe the Shinkos and having the ability to run them at low pressures had an effect on how well I started.

In my first outing with the Tubliss system installed I noted more grip going in and out of corners and had a lot more confidence on the bike than previously with my old setup. On more than one occasion I gained significant ground on other riders while climbing hills and navigating muddy terrain. In general, I felt this combination of tires and pressures responded very well to all the different conditions I encountered.

Pinch Flats and Rim Protection
I used to suffer pinch flats quite regularly with other setups, however to date, with the Tubliss system I have had no issues. I have run my Tubliss equipped tires into square cornered cement slabs at speed with no ill effects, blasted into logs, and slammed into countless rocks. One of the interesting things that happen when striking a sharp-cornered object with Tubliss equipped tires is that you can literally feel the tire deform and the high pressure bladder absorbing the blow.

Maintenance
Once installed the only maintenance that Nuetech suggested was to regularly check the tire pressures prior to going out for a ride. I did this religiously but never noted any pressure drops in the high and low pressure chambers.

Pros

  • Excellent customer support
  • Significantly improved traction
  • Great pinch flat protection
  • Easy to install
  • Easy to maintain
  • Pressure adjustment down to 0 psi
  • Expensive tires are not necessary

Cons

  •  Honestly, I've got nothing to complain about.

Conclusion

I don’t typically rave about products but after my experience with the Tubliss tire system this is one I wholeheartedly endorse. The impact the Tubliss system, equipped with the right set of tires, had on the level of traction I experienced was phenomenal. The fact that the Tubliss system appears impervious to pinch flats is icing on the cake.  

Adding the Tubliss system is a recommendation I will be making to anyone who will listen and ranks right up there with setting up the bike’s suspension for the rider’s weight, skill level, and discipline. Since the Tubliss system is sensitive to the type of tires used I would highly recommend that anyone considering installing the system do their homework or work with Nuetech on selecting the best tires for their application.

5 years and 23k , great product ( no pinch flats , low air pressure , easy plug fix flats , ) only thing i recommend is change your inner bladder once a year , they are cheap , ( 18 $ canadian) i did have a failure on a 3 year old bladder , ( Valve on inner tube gave up while i was testing pressure ) and i do test tire and bladder air  pressure  before each ride .

Followed instructions step by step had numerous leaks, both valve stems, don't waste your money.
Tire swaps about the same maybe easier with conventional tube.
