Syncros offers with the IS Cache 2.0 a practical all-in-one solution. A small tool and a chain riveter are concealed in the bottle cage. The holder for the pump can be mounted on both sides underneath the bottle cage. The bottle cage itself can be converted to left or right-handed use - so you have all the options for customisation.
Mounting the Syncros IS Cache 2.0 HV is a little more complicated than with a standard bracket and it is recommended that you use the long screws supplied for a secure fit. The tools can be used in different ways. Although the chain riveter is tiny, it is still easy to use. The small multi-tool, on the other hand, is a little angular in the hand and the lever is small. We would also have preferred a few smaller hexagon socket sizes instead of the 30 mm Torx. The 6 mm hexagon socket is made up of the 4 mm and 5 mm spanners and sits very loosely in the screw head.
The pump with its extendable hose is a good compromise between compact dimensions and volume. The pump head with lever encloses the valve tightly, but is somewhat awkward to operate. Pump carefully to avoid kinking the valve head.
Large bottles in particular sit a little wobbly in the holder. Unfortunately, not all repairs are possible with the Syncros IS Cache due to the lack of an Allen key. Before buying, be sure to check whether the most important screws on the bike can be operated with the tool.

- Tools can get dirty; bottle sits a little wobbly; bit selection not optimal; handling minitool
If you screw the Accessory Mount to the bottle cage hole in addition to the IS Cache, you are really well equipped for punctures. Here, a spare inner tube is securely fastened by the Velcro strap. You could also attach a tyre lever.
The scope of delivery also includes rubberised cable ties, which can be used to position the small bracket anywhere on the bike. Depending on the mounting point, the plastic of the bracket can be shortened.
It has taken a long time, but now Crankbrothers has also launched a series with integrated tool solutions. The BC18 is the jack-of-all-trades among the various options.
A bottle cage serves as the basis, which has been upgraded with all kinds of useful features. On board is a tyre lever with tubeless patch and piercing tool. An aluminium case on the side protects the minitool and chain tool from dirt. Clever: The mini-tool pops out of its case with a spring. Another clip holds the pump or CO2 cartridge (not included).
Off-road, the bottle cage scores with a firm fit. The water bottle hardly wobbles even in heavy bumps. The mini tool sits comfortably in the hand and the lever can be extended slightly by clipping the chain riveter to the tool via the connecting bar. It took us a while to get to grips with all the functions and tricks of the tool set. The following turned out to be particularly clever: The tyre lever acts as a handle for the chain riveter. The riveter itself also functions as a CO2 adapter and spoke tensioner.
During the test, we had the Klic HV pump mounted on the bracket. Its hose rattled slightly in the housing on bumpy forest paths. The Minitool was also minimally audible when shaken. Otherwise, the BC18 is currently one of the most comprehensive and best on-board solutions.
