Peaty's Rim Job rim tape

First impression
At first glance, many rim tapes seem very similar. The one from Peaty's also makes a "normal" impression, it seems to be somewhat inflexible. Interestingly, the tape is almost transparent. It is available in four widths from 21 to 25 millimetres.

Conclusion
The Peaty's rim tape differs from other tapes primarily in terms of transparency. Even after a year of use and several punctures, it is still tight and sticks well to the rim.

Milkit valve system

First impression
The valves from Milkit are strikingly different from other products. Their USP is the rubber flap at the end of the valves. The flap seals even when the valve core is removed. This greatly simplifies setup. Four different lengths are available.

In use
The valves are fitted to the rim as usual. Then remove the valve core and inflate the tire for the first time without tubeless milk. Ideally, this is done with a compressor or a booster. This presses the tire efficiently against the rim wall and, thanks to the self-closing rubber flaps of the valve, the air remains in the tire even without the valve core. Leaving the wheel like this overnight increases the chance of a good fit between tire and rim. The next step is to reduce the air pressure to below one bar, add the sealant and continue with the basic installation.

After a few months of use, the rubber flaps may stick together, especially in combination with tire inserts or if tubeless milk from manufacturers other than Milkit is used. This makes pumping difficult. Now there's only one thing to do: move the fully unscrewed head of the valve core in and out several times until the stuck flaps come loose.

Conclusion
The biggest advantage of the Milkit valves is that you can easily check the quantity and quality of the sealing milk. To do this, reduce the tire pressure to below one bar and check the filling quantity using the Milkit syringe. The process is well explained on the manufacturer's website. Another plus is that thanks to the rubber flaps, the air remains in the tire when pumping without a valve core. With other valves, it can happen that the air escapes so quickly when the pump head is removed that it detaches the tire from the rim edge again and the basic assembly drags on.

Schwalbe Tire Booster

First impression
Schwalbe's Tire Booster is a pressure reservoir that can be filled to a pressure of 11 bar using a conventional floor pump. A reversing switch releases the air "explosively" so that the tire is pressed against the rim flanks and seals. The bottle is around 37 centimetres high and weighs 435 grams; it is intended for use in the workshop or at home and not for touring.

In use
Very few people have a compressor at home and tubeless installation is often unsuccessful with a floor pump. The Tire Booster offers a remedy. Depending on the power of the floor pump, the tank is filled with eight bar in less than two minutes, which is usually enough. The adapter then needs to be screwed onto the valve - with the inner workings removed - and the air released using the switch lever. If the booster does not manage to press the tire completely onto the rim, the use of soapy water, tubeless sealant or a tire mounting fluid usually helps. Apply this to both sides of the tire bead and mount immediately with the booster. In the last two years, the booster has only failed with one tire and rim combination. But the use of a compressor was not easy there either.

Conclusion
The "Tire Booster" from Schwalbe can't quite keep up with the power of a compressor. In 90 percent of cases, it presses the tires close to the rim at the first attempt. Thanks to its compact size, it is easy to carry in your luggage.

Specialized Airtool Comp floor pump

First impression
The pump has a dual scale with an oversized pressure gauge. It has a measuring range from 0 to 2.2 bar for mountain bike tires and from 2 to 8.2 bar for road bike tires. The pump head fits both Schrader and Presta valves. And very importantly, thanks to the clamping head, the valve core cannot be accidentally unscrewed. The bright red color makes the pump easy to find, even in a messy workshop.

In use
The "Airtool Comp" pumps more efficiently than almost any other pump of a similar size. This is a great advantage, especially when filling the "Tire Booster". The handle is comfortable to grip and sits well in the hands during prolonged use. Furthermore, the dual display makes it suitable for all types of bikes.

Milkit Tubeless Sealant

First impression
The sealant from the Swiss company Milkit is a combination of synthetic latex and microfibers. As it does not contain ammonia, the smell is not as pungent as that of other manufacturers and it can be diluted with water. However, this is not recommended because it reduces the sealing ability. But it does mean that spilled sealant can be removed with plenty of water. In addition, the liquid produced in Europe is gentle on the hands and does not irritate the skin. Different sized containers are available, from the 60 ml version for refilling on the go to the 5 liter workshop canister. The sealing milk can be used without prior shaking.

In use
The manufacturer recommends around one decilitre of sealant per 29-inch tire. In practice, this is enough for around six months as long as the system is tight and you don't get a flat tire. Three months after the first tubeless setup, you should check how much milk is still in the tires. After that, intervals of six months are sufficient. The product seals small holes in the tire well, but larger holes require a tubeless patch, as is the case with most sealants. Whether a Maxalami, a Dynaplug or a Stan's Dart Plug is used is irrelevant. They all seal equally well.

Conclusion
The big advantage of Milkit tubeless sealant is its long shelf life. It takes several months for the liquid to dry out. Sticky valves are therefore a rarity. The "mild" ingredients are easy on the hands. The puncture resistance on the road is at an average, good level. Like most other sealant products, this sealant fails with cuts of more than four millimetres, so a patch is always necessary.
