The Tacx To Go Mini Chain Tool with Allen Key Set and Chain Rivet Extractor comes with 11 tools: 2.5, 3, 4, 5, 6 and 8mm hex keys, Phillips and flat-bladed screwdrivers, a pair of tyre levers and a chain extractor whose handle doubles as a second 5mm hex key. It weighs 170g.
The multi-tool’s smooth plastic case and self-contained design mean that even though it measures 105x45mm, its slim 14mm depth slips into your jersey pocket or saddle pack with minimal fuss.
Its broad shape offers you plenty of leverage but the 45mm width can be restricting, which is also true for the 25mm-long tool bits that slot into the 8mm hex key.
These are neatly stored under one of the tyre levers and held in place by powerful magnets so they don’t accidentally fall out no matter how much you knock them — but this does make it a little fiddly to pull them out with gloves on.
The tyre levers have a great bead hook but do flex a little under strain, though the U-shaped channel stops them breaking.
The neat chain tool works well, its nicely knurled bolt head making it simple to align with a chain pin. The result is that this has everything you’ll need from a multi-tool in a well-packaged design and at an attractive price.
