First Look – Revo Loop Tubes

I know that like many of you boys and girls out there in bikeland there’s a fat-bike in my care that still uses inner tubes. I run tubeless in most of my bikes but I still carry a tube with me on every ride (just in case). Today we’re going to take a look at a new lightweight tube from a German Company called Revo Loop.

We’ll be testing two different fat-bike sizes of these new tubes. 26×3.8-5.0 and 27.5×3.8-5.0. The 26″ versions going into an old-school blaze orange 9:Zero:7 and the 27.5 version going into the repair kit that I carry on my Fatback Corvus FLT.

The Revo Loop tubes look and feel like really thick zip-lock freezer bags. They’re made with thermoplastic polyurethanes. The valves are also molded thermoplastic and they’re recyclable.. Since both the seamless tubing and the valve are made of TPU, Revo Loop bicycle tubes can be completely recycled. The TPU material is considerably lighter than butyl rubber used in regular innertubes.

How much do they weigh?

How Much Weight Can it Save?

Scenario 1 – The Extra Tube

I normally carry a Q-Tube 26 x 2.4-2.7 in my pack, but those weren’t available last summer, so I’ve been carrying this 320 g – 26×3.0 tube around in my frame pack. The new 27.5 x 3.8-5.0 Revo Loop tube saves 165 grams (almost 6 oz).

It also takes up less volume in the pack. That leaves more room for snacks!

Scenario 2 – Replacing Regular Tubes

My wife’s sassy little 9:Zero7 has been rocking a pair of Specialized 24×2.3-3.0 Tubes for the last few years. (Remember when those were cool?)

I replaced the old tubes with the new Revo.Fat tubes and that saved a net of 230 g (7.16 oz). The installation went very smooth. The plastic tubing doesn’t bind with the rubber of the tire like a standard tube. They went together in a snap and so far – so good. I weighed a standard Specialized 26 x 3.8-4.8 tube (photos below) and It was 550 g. If you still have the standard tubes that came with your bike. They’re probably closer to those tubes than the lighter weight/size tubes that we use here. If you replaced a stock fat bike tube with the Revo.Fat Tubes in both wheels you would save 794 grams (one pound twelve ounces!)

So if you’ve never wanted to deal with sealant and all of the joys of running your fat-bike tires tubeless, you can still significantly reduce the rolling weight by switching to this high-performance, long-lasting and lightweight alternative to standard inner tubes. Revo Loop claims that their material has better puncture resistance than standard tubes, but they sell a patch kit just in case you get a puncture. We’ll be riding these tubes and after a year or so of riding come back with some thoughts on how puncture-resistant that they might be.

The jury is still out about how they ride. The good news is that we get to ride a bunch more to figure all of that out. Revo Loop isn’t the only lightweight and packable tube solution on the market. Tubolito also makes an alternative inner tube solution that’s been on the market. You can learn more about Revo Loop Tubes by visiting – revoloop.com

    So the review shows a 27.5 fat tube but I can’t find that anywhere.

    I ordered one of this for my fat bike and put it in and added a bottle of Flat Attack flat sealer. We will see how it does out here in the California desert.

      Larry, any feedback on how these tubes have worked?

    Two tubes deployed and two tubes flatted in very short order – No Bueno. Tubeless is the way to go.

      Dude. Same just happened to me. Fortunately I was close to the trailhead (and heated garage) at Cam-Rock. Very disappointing. About to go fix this mess, did you determine why yours failed?

        a tiny puncture on the one that I recently replaced – I’m carrying Tubilito tubes in my oh shit kit these days.

    Gomez what size tire does your spare Tublito fill?

    I contacted Tublito and was told they don’t have a tube that fits fat bikes yet.

    Also read an MTBR thread on a using plus sized Tublito as a spare and members couldn’t get the Tublito to fill a 4” tire even at high pressures.

    I appreciate your comments. Thanks for keeping it real.

      Uhh Oh…I was carrying the largest size tubilito that they offerered (27.5+) and I just tried it without success. Back to carrying a 26 x 2.4-2.7 tube.

    What do you think about a well Revo Loop (kept in a nice ziplock bag) AND a Revo compatible patch kit as back up?
