This tubeless rim-strip makes tubeless conversions easy and quick. Unlike its butyl predecessors (from other brands), Caffélatex Strip is very light, puncture-proof and transparent. Made using a proprietary polymer blend, it is available in nine widths and two different wheel diameters each (26”/27,5” and 29”).Each kit contains two rim strips complete with tubeless valves. Mounting instructions are shown on the back of the header card.Why use a Strip when we already have a tubeless conversion tape?For some applications, the tape is great and it will always be lighter than a strip (8 g against 29 g per wheel... a butyl strip is around 65g). However, the tape takes time and some care/experience to be installed properly. There are then some applications where the tape simply won't work. i.e. the new cut-out rims for the new “+” and FAT size rims.Sold as kits containing two rim strips and two 40 mm tubeless valves (2 wheels per kit)Specifications:Small: 20 - 24mmMedium: 25 - 29mmLarge: 30 - 34mm27.5 Plus Small: 35 - 40 mm27.5 Plus Medium: 41 - 45mm27.5 Plus Large: 46 - 50mm26 Fat Small: 60 - 65mm26 Fat Medium: 75 - 80mm26 Fat Large: 95 - 100mm

This product has been carefully formulated to deliver TORQ’s unique blend of multiple-transportable carbohydrates and electrolytes to the working muscles extremely quickly and efficiently using research-proven 2:1 Maltodextrin:Fructose technology and all 5 key electrolytes.This gel also contains 89mg of natural caffeine delivered by Guarana Extract. Caffeine has been found to increase alertness, mental agility, muscle function and assist the fat-burning process among other benefits.TORQ Gel forms part of the TORQ Fuelling System, so can be used alongside TORQ’s energy drinks, bars and chews to fuel optimal performances. Please Note: This product contains high levels of caffeine and should be used in conjunction with TORQ’s other non-caffeinated gels and other Fuelling System products.Each TORQ gel (whether caffeinated or not) provides 30 grams of multiple-transportable carbohydrates (1 TORQ Unit), which is a significantly greater concentration than many brands on the market today featured in larger heavier packages. For optimal performances, our TORQ Fuelling System recommends consuming 2-3 TORQ Units per hour which can be achieved through consuming a variety of fuelling products.The higher your perspiration rates, the more TORQ Energy Drink you will need to consume relative to our more concentrated fuelling units – TORQ Gels, TORQ Bars and TORQ Chews. All of our fuelling products are optimised with multiple-transportable carbohydrates, the only difference between them is the texture; Smooth, Soft or Chewy. Key Features: With Guarana (89mg Caffeine), 2:1 Maltodextrin:Fructose, Multiple Transportable Carbohydrates, Contains 5 key electrolytes, Silky Smooth Texture, Part of the TORQ Fuelling System,.Guarana: This gel contains 89mg of natural caffeine delivered via Guarana Extract. Caffeine is a psychological stimulant, so aids mental concentration. The TORQ Fuelling System will allow you to follow an effective fuelling strategy, which will ensure that your muscles and brain will always have the energy they need to deliver the best performances. Caffeine doesn’t provide any extra energy as such, but it does deliver the perception of energy by up-regulating the central nervous system – this is why a coffee can mentally perk you up when you’re feeling a bit sleepy or can’t concentrate. Taking this product occasionally instead of a non-caffeinated fuelling unit can be used as a tool to boost flagging concentration and motivation.Caffeine: is essentially a central nervous system lubricant, so as well as boosting concentration and motivation it can increase muscular power and efficiency as well as mobilising fat as a fuel source, helping to spare glycogen (your carbohydrate reserves). For these reasons, there is a strong argument that caffeine should be consumed routinely during exercise/competition to boost physiological as well as psychological performance.Multiple-Transportable Carbohydrates: TORQ Gel utilises a 2:1 blend of glucose-derivatives and fructose founded on a now substantial body of peer-reviewed published research (see References tab). The carbohydrate sources for TORQ Gel come from an extremely low osmolality maize-derived maltodextrin (a long chain glucose derivative) and fructose. This dual-delivery carbohydrate formulation has been proven beyond doubt to supply energy faster than any other combination of carbohydrates or single carbohydrate source formulations.Here we thoroughly explain the research and why we have incorporated it into this product and others in the fuelling range.Hypertonicity: The concentrated high grade, low osmolality maltodextrin used by TORQ pitches TORQ Gel’s tonicity firmly into the hypertonic zone, meaning that the product has been optimised to prioritise fuel delivery over fluid supply. This, in combination with the unique integration of multiple-transportable carbohydrates and its smooth, easy to swallow texture, makes TORQ Gel highly potent and the fastest delivering fuel source on the market today. Hydration Management: TORQ Gel will not satisfy your hydration requirements (no gel on the market will, despite claims made claims by some isotonic gel manufacturers), so it is vital that you use this product in conjunction with TORQ Energy Drink to ensure optimal physical performance. As the TORQ Fuelling System confirms, you may experience high perspiration situations where the intake of TORQ Gel units should be limited in favour of TORQ Energy Drink consumption to address the body’s fluid and electrolyte requirements. On the other hand, in low perspiration environments, TORQ Gel and our other concentrated TORQ Units such as TORQ Bar and TORQ Chew should represent a more significant proportion of your fuel intake. As long as 2-3 TORQ Units per hour is maintained in every scenario, fuelling will be optimal, you just need to drink more of your fuelling units if perspiration rates are high and less when lower. The infographics and videos in the previous tabs clearly illustrate this concept.Electrolytes: TORQ Gel contains Sodium, Chloride, Magnesium, Potassium and Calcium to replace the 5 electrolytes lost through perspiration. These salts maintain homeostasis within the body, allow it to hold onto water and preserve muscle function.Gluten Free & Vegan Formulation: TORQ Gel is a gluten-free fuelling product. The formulation for TORQ Gel is also entirely plant-based, so is suitable for Vegans. Natural Flavours and No Colours: Under exercise stress, digestion is affected as blood is diverted to the working muscles and any solutes added to a product will raise its osmolality unnecessarily making it harder to digest, so irrespective of the health debate surrounding the consumption of artificial ingredients, during exercise is certainly not the time to take them. Therefore, we only use natural flavours that the body can recognise and break down easily and we don’t use colours (artificial or natural), because they simply don’t need to be in the product. No Artificial Sweeteners: For the same reasons as highlighted above, we don’t believe in the use of artificial sweeteners like Aspatame, Acsulfame-K, Saccharine and Sucralose. These artificial sweeteners are 100’s of times sweeter than sugar and Aspartame/Acsulfame-K are particularly controversial with regard to long-term health. They offer no performance benefit at all and our stance is the same with these as with colours and preservatives – if they don’t need to be included in our formulations for functional reasons, why include them?The research is clear, fuelling with carbohydrate and ensuring that you consume a Recovery Drink immediately after exercise will not only boost performance and assist in the overall recovery process, but it will also support your immune system, leaving you less vulnerable to infection.

Not all modern mountain bike rims are tubeless compatible, so if you want to take the tubeless plunge but don't want to invest in new wheels, the Effetto Mariposa Caffelatex Tubeless strip is the answer.Lightweight, puncture resistant transparent rim strip makes tubeless conversion easyFit strip and valves to wheels, add sealant to tubeless or tubeless-ready tyres, inflate and go for a rideLong lasting construction can be moved from wheel to wheelSold as a kit including two rim strips and two 40mm tubeless valvesWhile more and more rims are designed from the outset to be used with tubeless and tubeless-ready tyres, there are still a huge number only designed to take tubes. Rather than investing in a new set of wheels, the Effetto Mariposa Caffelatex Rim Strip allows you to convert your regular inner-tube only wheels to tubeless-ready, so you can enjoy puncture-free riding.When using the Caffelatex Rim Strip, you can remove your current rim tape or cloth and install the strip. This is the first step in setting your wheels and tyres up tubeless. The strip helps to make the rim as air tight as possible. When combined with the tyre sealant, this keeps the tyres inflated and more resistant to punctures. The width of the tape varies, so you must select the right size for your rim. The Small Kit suits rims with an external section of 20-24mm, Medium suits 25-29mm and Large suits 30-34mm wide rims. Once the strip and valves are installed you can install your tubeless or tubeless-ready tyres, add your sealant of choice, inflate the tyres and you're good to go! You can finally kiss punctures goodbye. The strips and valves are incredibly durable, so you can easily swap them between wheels if you need to. Thanks to the Effetto Mariposa Caffelatex Rim Strip, you no longer need to have a set of expensive tubeless or tubeless-ready wheels to enjoy the benefits of such a setup.
