One of the most interesting new multi-tools spotted at Interbike 2015 was the Fabric Chamber. Weighing in a 162 grams, the tool is small and light enough to easily pocket. Housed inside the chamber are 6 double-ended bits and an 8mm over-bit that all fit the ratcheting head for trail or road side repairs. The tool serves 13 functions (14 if you smack something with it like a hammer, though this is probably not recommended) and since the bits can be positioned at different lengths in the chamber head, it should be a lot easier to work with than many folding multi-tools on those hard to reach fixes.
The Fabric Chamber lists for $60 and should be available soon. A non-ratcheting version is available for $10 less.
