Review on 🚲 WOTOW Bike Repair Kit Set, 16-in-1 Bicycle Multitool Hex Key Wrench & Tube Patch Kit & Tire Lever with Hard Carrying Case - Portable Cycling Maintenance Fix Set for Road Mountain Bikes by Michael Morgan

Includes all the necessary tool sizes for most nuts, bolts, hexes and screws on a bike. Comes in a small packaging with a nice hard case. See photos with dollar bill for size reference. The case even offers space for additional screws and a small tool. The suitcase fits in a small bag under the seat, in which I also carry a digital pressure gauge. This tool set should be enough for emergencies on the go. An additional 4mm hex key is suitable for hex bolts designed for accessories such as bottle cages and a pump. This extra 4mm Allen key is included in case you need to tighten the screw that holds the tool kit together. I just got this kit and haven't used it yet, but I know it will come in handy at the track. Update August 2019: I just replaced the stem and obviously I didn't tighten the bolts enough. (I just ordered a torque wrench to fix this problem). Struck on a boulder at the wrong angle on the trail and the stem rotated about 15 degrees. I used my handy dandy tool kit to re-tighten the bolts and continued my ride.
