Fabric’s Chamber comes equipped with 13 tools: 2, 2.5, 3, 4, 5 and 6mm hex keys (the 8mm key fits over the 6mm one); you also get size 3 and 5 flat-bladed screwdrivers, size 1 and 2 Phillips head and T10 and T25 Torx bits. It weighs 162g.
The Chamber’s self-contained design means there are no parts that can snag or open when you stuff it into your jersey’s back pocket. The 95x25mm size also means it won’t take up much real estate in your pocket or saddle pack.
The tool’s unique ratchet head could be seen as a gimmick — but the T-bar system is a very effective piece of design.

You can lock the tool’s 70mm-long double-ended bits into three different positions, allowing you to reach hard-to-access bolts easily and still tighten or loosen them with the ratcheting head.
The Chamber features a good selection of tools too, as they’re the ones that will deal with on-the-fly adjustments and get you out of most mechanical jams. But the always-prepared ex-boy-scout-style riders will still need to carry tyre levers and a chain tool — fine if you use a saddle pack, but more of a faff if you carry kit in your pockets.
It is worth considering, as it is an innovative and effective piece of kit, but the lack of a chain tool reduces its universal appeal.
