Syncros Boundary 1.5HV mini pump

First impression
119 grams in weight, 210 mm long and therefore a good average size. The attachable pump head with locking lever is absolutely great. Because there is nothing more annoying than pumps with a twist lock, which unscrew the valve heart when decoupling and let all the air escape again. The locking lever has another function: it covers the pump hole during transportation and prevents dirt and liquid from entering. This is particularly practical when carrying the Boundary mounted on the bike frame or bidon holder. Another highlight of the hand pump is the extendable pump head. It reduces the risk of damage to the valve stem during inflation. A bracket for mounting on the frame is included

In use
In terms of the number of strokes it takes to inflate a tire, the Boundary is in the middle of the field compared to other products. However, it requires noticeably less effort over the duration of pumping than other hand pumps. There were never any problems, neither during testing in the workshop nor during punctures off-road.

Conclusion
The Syncros Boundary 1.5HV is an absolute top pump for on the road. The combination of clamp head and pull-out function makes it a favorite. The robust construction and compact design round off the product. Finally, the common problem of unscrewed valve cores is history.

Syncros Boundary 1.0 SH damper pump

First impression
Weighing 177 grams and 210 mm long, these are the key data of the mini shock pump. There are more compact solutions, but the highlight of the Boundary is that it contains the same digital measuring device as many of the common workshop damper pumps. This ensures that the desired pressure is exactly right, even in the field. The display has a measuring accuracy of 0.01 bar or 0.1 psi and has a plastic display protector. An air release knob is located on the back of the head.

In use
The end button on the pump shaft is not particularly ergonomic, but it does not restrict pumping. If too much air is pushed into the suspension elements, it can be released very easily using the rotary knob. Otherwise, it works in the same way as shock pumps from other manufacturers and requires a similar number of strokes.

Conclusion
The pump is suitable for use in the workshop as well as on the road. The display protection is practical and useful for the latter. A very small Torx key is required to change the battery. This is the only drawback of the Syncros Boundary 1.0 SH.

Pro Minitool 22

First impression
60 x 90 x 30 millimetres when packed and weighing 180 grams: not top values, but perfectly acceptable. Other values are decisive for the selection in this test. The set contains the most important tools you need on the go and even a few more - all in a compact space. The Pro Minitool 22 includes:

• 2/2.5/3/4/5/6/8 mm Allen key
• 10/25 Torx
• PH2 cross
• 3.6/3.75/4.0/4.4 mm spoke wrench
• 7/8/9/10 mm wrench
• A wide tire lever
• Chain rivet pusher
• Chain holder
• Brake pad spreader

The whole set comes in a practical case made of robust material. All tools are labeled with an engraving, so even the inexperienced can quickly find the right size.

In use
The individual tool elements are rather short, but you can still reach most of the screws on a bike with them. Only when the pedals are stuck can you reach the limit due to the short design of the tool, which means you have to give up. But this is usually the same with other tools. Thanks to the very robust design, however, there is no risk of the tool warping when a lot of force is applied. The rivet pusher also cracks old and bent chains with ease. There are limits to the tire lever. It usually lifts trail and enduro tires off the rim without any problems. For downhill tires or stuck rim-tire combinations, a second tire lever is required, which is ideally longer in order to build up more force.

Conclusion
You can tell the Pro Minitool 22 has Japanese roots: a simple design, everything reduced to a minimum and yet practical. The absolute opposite of the many over-designed tools currently on the market. Unfortunately, the tool is not made of stainless steel, but only has a chrome coating. It is therefore uncertain what the durability will be like.

Topeak Power Lever X

First impression
A weight of 93 grams and a length of 153 millimetres are not the kind of mass for a tire lever that you want to lug around. However, these long levers are the ideal complement to the mini-tool listed above. Because sometimes there is no way around two robust tire levers to be able to balance tires from the rim. But the Power Lever X offers even more: they also serve as chain lock pliers and include a chain holder and a recess for removing the valve core. The two levers are held together by two steel pins. The chain holder is located on the inside of one lever, while the second lever has a parking space for a spare chain lock.

In use
The name says it all, thanks to the combination of hardened steel and a fiberglass composite plastic, the Power Lever can lever even the fattest tires and tightly stuck rubber off the rim. The length of the tool enables high power transmission. To use the levers as chain tongs, connect them to the left-hand pin. The chain is then fixed in place with the retaining clip so that there is no tension on the chain lock. This makes it very easy to open even crooked locks. If you connect the levers to the right-hand pin, you can apply tension to the chain lock and lock it.

Conclusion
The Power Lever X from Topeak may be a little bulky, but a tire lever of this type is often necessary to repair a flat tire and allow you to continue riding. The combination with the chain tool makes them almost indispensable.

Peaty's Holeshot Tubeless Puncture Plugger Kit & CO2 Tire Inflator

First impression
The two products are available in 12 color variants, matching the anodized colors of the Chris King products. There is something for everyone, to match your bike or clothing

The Puncture Plugger is in two parts. If you unscrew the lid, the actual plugger emerges from inside. The second part is a kind of handle extension. This is screwed onto the thread on the top of the lid. Thanks to the rubber seals, the parts can be firmly connected and easily detached again. They also prevent water from getting into the tool and the spare patches from getting wet. The asymmetrical hook makes it easy to load the salami sausages. These should remain securely in the tire after insertion and not be pulled out again. The file-like shaft of the fork is used to "clean" the holes before the salami sausages are pushed in.
The recess around the spike holds spare patches. Three of these are supplied in 1.5 and 3 millimeter thicknesses.

In use
Depending on the nature of the hole in the tire, it may be helpful to first insert the plugger without a patch and roughen the hole. For example, for very small holes, when there is only thick salami left. The plugs can be inserted quickly and easily through the large fork opening. Ideally, the plugger should be held like a syringe so that it can be rammed through even thick carcasses. This works much better than with the usual forks. Once the tire has been patched, the inflator comes into play. Simply screw in a CO2 cartridge as far as it will go, position the wheel with the valve facing downwards and attach the inflator. Press the cartridge with a little force and the gas shoots into the tires. The pressure built up unusually quickly and pushed the tires completely out to the edges of the rim in all punctures.

Conclusion
Tubeless repairs are rarely as easy as with the Holeshot tools from Peaty's. As they are slim, you can stow them within easy reach in the outer pocket of your shorts or in the waist belt of a rucksack.
