Effetto Mariposa Caffe Tubeless Rim Strip Fat M 26/27.5 Pair

Easy Tubeless Conversion
Caffélatex Tubeless Strip Plus/Fat is a lightweight, puncture-proof and transparent tubeless rim strip that makes tubeless conversions quick and easy. The rim strip allows tubeless conversion of most Plus and Fat mountain bike wheels, using Tubeless or Tubeless-Ready tyres and Caffélatex sealant. The strip isn’t adhesive, it’s made in one piece and relies on its elasticity to sit tight on the rim. Caffélatex Strip is the ultimate tubeless solution for very difficult rims (for example, cut-out Fat rims, aluminium rims with mat surface finishing, carbon rims with mould release treatment – where no tape sticks very long, rims with very deep channel, pin-joined rims where the junction is not welded etc.).

Highly Resistant to Damage
The special polymer employed in its construction makes Strip highly resistant to damage and puncture. It is also chemically stable and cannot be damaged by Caffélatex or other non-chemically aggressive tyre sealants.

Installation
To convert a rim to tubeless, simply remove the existing rim-strip, choose the appropriate Strip size and follow the following easy steps:
• (OPTIONAL STEP, NOT FOR CUT-OUT OR SINGLE WALL RIMS) Use a roll of electrician tape and seal the spoke holes of the rim. This just to ensure sealant is prevented from getting inside the rim inner chamber, in the unlikely case the Strip moves and lets some liquid through.
• Insert the provided Caffélatex Tubeless Valve in the Strip, so that the rubber base is in contact with the strip.
• Secure 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 proper air-tightness.
• IMPORTANT: some single wall rims (mostly aluminium, cut-out rims for fat bikes) might require fitting an additional washer under the nut, before threading it against the rim. We provide one additional washer per valve for Plus L and all Fat Strip.
