I am often riding my bike and I wouldn’t say I’m exactly a light rider, Even with hopping curbs and riding through thick grass can cause problems like a flat tire or a slipped chain. This repair tool and set comes with everything I’ll need to fix any hardware that might fail during my ride. I already carry a hand pump and this paired with the repair tool and a tube of tube adhesive I wont have to ever worry about a flat or a loose chain. The tool has 6 allen wrenches 1mm – 6mm, 1 flat head screwdriver, 1 philips screwdriver, 1 socket extender, 3 sockets 8mm – 10mm, a wrench 8mm – 15mm, a 14GE gage on samw wrench, 2 tire removal tools, a metal pad that has teeth to rough up the smooth tube when trying to glue the tire patches to it, and finally the tire patches. Everything I need in one place for any issues I might come across on a daily basis when riding my bike or for emergency situations such as a flat tire. I have been stranded in the past when riding my bicycle with a flat tire and let me tell you, Its not any fun walking 10 miles back home pushing a bike while people drive by and stare at you wondering why your walking a bike instead of riding it. This is a great took for bike riders everywhere, Repair a loose spoke or just tighten a screw that keeps the break handle attached to the bike. The nylon case that this tool comes with makes it easy to attach to my bike with a few zip ties. Just slip them under the loop and tighten around the main bar on the frame of the bike. I have it right next to my hand pump so it is very easy to get to. I picked this off of a list of things needing a review at a discounted rate or free and gave my unbiased honest opinion.
