Caffélatex Tubeless Strip

Caffélatex Strip is a very light, puncture-proof and transparent tubeless rim strip that makes tubeless conversions quick and easy. Caffélatex Strip allows tubeless conversion of most standard mountain bike wheels, using Tubeless or Tubeless-Ready tyres and Caffélatex sealant.

EXCLUSIVE FEATURES:

  • easiest way for tubeless conversion
  • lightest tubeless rim strip in the market
  • long lasting, can be moved from one wheel to another
  • extended range of widths
  • puncture-resistant

CHARACTERISTICS:

Available in different sizes:

Caffélatex Strip is available in three widths, two different wheel diameters each (26”/27,5” or 29”), for a total of six options. Sold as kits containing two rim strips and two 40 mm tubeless valves (2 wheels per kit):

  • Strip S 26″/27,5″ (x2)
  • Strip S 29″ (x2)
  • Strip M 26″/27,5″ (x2)
  • Strip M 29″ (x2)
  • Strip L 26″/27,5″ (x2)
  • Strip L 29″ (x2)

The three widths are:

  • S (25 mm): for rims with external section between 20 and 24 mm;
  • M (30 mm): for rims with external section between 25 and 29 mm;
  • L (35mm): for rims with external section between 30 and 34 mm.

Lightweight:

30 g for a Strip S 26″/27,5″ make it competitive with tubeless tape (with a weight ranging between 9 and 20 g per wheel) and simply superior to old butyl liners (with limited strength and adding over 65 g per wheel). Weights(*) for a single Strip, for each size are:

  • Strip S 26″/27,5″: 30 g
  • Strip S 29″: 33 g
  • Strip M 26″/27,5″: 36 g
  • Strip M 29″: 39 g
  • Strip L 26″/27,5″: 48 g
  • Strip L 29″: 53 g

(*) tolerance +/- 10% on nominal weight

Max pressure:

Up to 7 bar (100 psi). Depending on rim width, Caffélatex Strip is easy to use for adventure road cycling and wider road tyres.

Highly resistant:

made using a proprietary polymer blend, Caffélatex Strip has very high mechanical strength and resistance to punctures. It’s also very stable from a chemical standpoint and cannot be damaged by water or Caffélatex.

WARNING: using sealants containing aggressive chemicals or ammonia, or cleaning the rim with aggressive chemical products can damage Caffélatex Strip and may represent dangers to the user. We recommend using only Caffélatex sealant or Espresso inflate & repair cartridge with Caffélatex Strip.

Easy to use:

Caffélatex Strip is the ultimate tubeless solution for very difficult rims (aluminum rims with mat surface finishing or carbon rims with mould release treatment, where no tape sticks very long; rims with very deep channel, asymetric spoke-holes; entry level pinned rims where the junction is not welded).

Five easy steps for tubeless conversion, using Caffélatex Strip kit
Five easy steps for tubeless conversion, using Caffélatex Strip kit

To convert a rim to tubeless, simply remove the existing rim-strip, choose the appropriate Strip size (chart above) and follow five easy steps (pictured):

  1. Insert the provided Caffélatex Tubeless Valve in the Strip, so that the rubber base is in contact with the Strip (as in picture, #1);
  2. Secure the Strip to the rim, tightening the nut on the valve stem. It’s important to push the valve base against the rim while doing so, to achieve a better air-tightness;
  3. Keeping the wheel with the valve at 12 o’ clock, finish mounting the Strip onto the rim;
  4. With a screwdriver or a similar tool, center the Strip inside the rim channel;
  5. Look at what you did and say “Wow, that was easy!”

F.A.Q.:

Why introducing the Strip when you already have a tubeless conversion Tape?

For most applications adhesive tubeless tape is great, and it will always be lighter than a tubeless rim strip. A layer of our Tape weights around 10 g per wheel, our Strip is around 30 (but note that a butyl rim strip is around 65g).
However, tape requires time and some basic mechanical skills to be installed properly: the Strip can be mounted in a couple of minutes and will work flawlessly even with deep-channel rims or asymmetrical rim shapes.

Unlike adhesive tapes that stay inside the rim channel, the Strip climbs on rim internal walls and in some cases can be seen from the outside, when the tire is mounted. Why?

The idea is to create air tightness between the tire and the Strip, especially useful for pinned rims: in those rims the junction is not welded, and sealing the spoke holes in the rim channel is not enough as selant/air can seep through the rim walls at the junction. As the Strip is born to be the ‘no problem’ tubeless converter, we have to cover also those  rim types.

Beside being easier to use, what’s the advantage of the Strip over tapes?

Something you can do with the Strip that you can’t with tape is moving the Strip from one rim to another. As the Strip material is very durable, its lifespan can exceed the one of the rim it’s mounted on, and can be removed and mounted on another rim.

The Strip is puncture proof. Why?

Being resistant to cuts/puncture, the Strip is immune to the tyre-lever damages that were so common on butyl tubeless liners. The puncture resistance becomes more relevant when using the Strip on cut-out rims.

My rim has a Schrader valve hole (diam. 8,5 mm). Should I use a valve adapter?

The Strip will easily convert any Schrader-drilled rim, no need for any adapter (just use the provided tubeless valve and insert it in the Strip before mounting the Strip on the rim, as described above).

  1. Hi,

    I want to use this on Velocity Aileron 700c (21 internal, 25 external), but you only have 26″/27.5″ and 29″, which one will work on my rim? As for the width, I presume I’d have to go with M?

  2. Hello. I’m planning 700×32 tubeless tyre mounting on a pair of Felt RSL3 TR disc wheels (ext. width 22 mm), using these strips. Are they suitable for road wheels? Do you confirm putting tape under the strip is unuseful?

    1. Hello, even if you could avoid it, you can certainly put adhesive tape under the Strip. The only drawback is that this will furtherly increase the effective diameter of the rim channel (given the thickness of tape + Strip), making some tires more difficult to mount.
      As for using Strip S on your Felt disc wheels: there’s no problem, just be aware that – given the way Strip works – the Strip might climb a little on the rim channel walls, or even show slightly from the outside. This is normal and won’t compromise safety of functioning.
      Unlike (adhesive) tapes, a tubeless rim strip must be in contact with the tire talon to ensure air-tightness.

  3. sorry your measurements are wrong. on a hed ardennes + (25mm external) there is no way to get a M size strip to align in the rim without blocking the bead from seating, and it does not allow the tire to seat evenly. Wasted $35 USD to find this out but it is a fact. external width does not provide a good measurement.

    1. Even if the Strip climbs up on the internal of the rim channel it won’t prevent the bead from seating.
      Infact, the Strip might come up and show from the outside, and still provide a proper functioning at road tubeless pressures (below 100 psi).
      I agree with you that tubeless tapes are normally just covering the bottom of the rim channel, sealing the spoke holes… but the Strip (and tubeless rim strips in general) is functioning in a different way and the tire talon must be in contact with it to provide a proper sealing. That’s why our Strip covers a wider rim surface than our T.less Tape.

  4. Hello,

    I have a pair of shimano mt15 wheels (pinned rim joint) I’d like to convert. I made two strips of soft plastic to test fit: one 25mm wide and one 35mm wide (as I understand, the same sizes as the Small and Medium Caffelatex strips), and pressing those into the rim, the Medium sticks up and covers the bead hooks, but the Small just reaches to the sidewalls. Which is preferable? For reference, the rims measure external width 25mm and then internally, 19mm wide, 7mm tall sidewalls, and 10.3mm deep to the spoke bed.

    1. Hi Eric,
      our “M” strip is 30 mm wide and it’s the one we’d recommend for rims with external width between 25 and 29 mm.

  5. Hello,
    What is the thickness of the rim strip material? About 1mm?
    Is there any issue using tape in conjunction with these tubeless strips, or would that be unnecessary added weight?

    Thank you.

    1. Hello,
      correct, our Strip has a thickness of 0,8 mm.
      You can add the Strip over Tubeless Tape, it will work… but it’s overkill (Strip or Tape can each function alone, you’ll be carrying unnecessary weight).

    1. The answer is yes: just fit the provided tubeless valve as described in the instructions and the air tightness will be good at tubeless pressures (up to 3 bar/ 45 psi). The conic adapters we normally supply with our valves are needed with tubeless tape… but the strip fits very tightly on the valve rubber sleeve, the valve alone provides already a perfect air tightness. Being able to fit also schrader-drilled rims was important while developping the Strip. We’ll highlight this in the strip webpage above, thanks for your question!

  6. Hello,
    i have a 24,6 mm rim (mavic crossride 29 wheels)
    it does not have deep-channel,
    what size should i buy, S or M?

    1. Hello, between 24 and 25mm both sizes (S and M) are ok but, give the shallow channel, I’d say Strip S is enough.
