I've had the Crank Brothers TT17 Twin Tube Tool Kit in my saddle bag for a few months now, and I've put it through its paces on some of the toughest trails in the area. First impressions were that the kit is impressively compact, weighing in at just 220 grams and measuring a mere 15 cm in length. The build quality is top-notch, with a sturdy aluminum construction that feels reassuringly solid in the hand.
One of the standout features of the TT17 is its versatility. The kit includes a range of tools, from a compact multi-tool with Allen wrenches and Torx bits to a tire levers and a chain breaker. I've found the multi-tool to be particularly useful, with the 3, 4, 5, and 6 mm Allen wrenches proving to be just the right size for adjusting my stem and handlebars. The tire levers are also a welcome addition, making quick work of removing stubborn tires.
In terms of performance, the TT17 has been a revelation. I've used it to make a range of repairs on the go, from fixing a punctured tire to adjusting my derailleur. The tools are designed to be ergonomic and intuitive to use, making it easy to get the job done
