The BRK-1 is the ultimate mobile bicycle mechanic tool kit. This tailored selection of 100 professional-grade bike tools was carefully chosen by Park Tool's team of experienced mechanics, with a comprehensive offering of the tools you'll need to adjust, replace, diagnose, and repair most components on a bicycle. Whether you're working in a professional race pit, neutral support tent at a local event, or the trailhead parking lot, you'll have the tools you need — and none of the tools you don't. The BRK-1 was designed around our BX-3 Rolling Big Blue Box, a professional-grade toolbox for the professional bike mechanic. When open, the BX-3 is a neatly-organized display of your tool collection, featuring dual-sided pallets with hundreds of custom-designed loops and pockets. The BX-3 has room to grow your tool collection even when fully loaded with the contents of the BRK-1. When closed, the BX-3 is built for travel, with a tough weather-resistant outer shell, integrated wheels and an extendable handle. BX-3 Dimensions: 23.4" x 17.3" x 9.3" (59.5 cm x 44 cm x 23.5 cm) Weight: 48.5 lbs (22 kg)
