ROCKBROS 23-Piece Bike Repair Tool Kit - Professional Bicycle Maintenance Tool Set for Tires, Brakes, Chains & Pedals - Perfect for Road & Mountain Bikes - Essential for Home Repairs & Outdoor Cycling Adventures

At the time of this review, this tool set is currently listed for $115, less a 20% coupon.Having worked on my own bikes for the last several years, I can tell you that it's not as difficult as it might seem (loads of instructional videos are available online). However, you do need tools (and a repair stand) to get the job done.I've generally purchased tools as needed, however, this can often leave you in situations where you don't have a tool handy when you need it; it also costs more to do it this way.Having a kit like this gives you a great platform to work off, and more tools can be added as you need them. Being a self-contained tool kit, there's no physical space to put more tools in the hard case, but it is neat and compact for what it does carry.Of the included tools, the only one that I think is a waste is the tire pressure pen. I say that because you'll need a pump anyway, and getting a pump with a gauge is going to be far more convenient to use.The other tools are quite common for a large number of bikes, and this set also makes it easy to work on older bikes (like my 90s MTB) without any real problems.Granted, the quality of these tools is not premium. They will get the job done, and work well for a home mechanic, but if you're getting paid to repair bikes, you'll want a more robust (and complete) set.One other tool that I'd recommend supplementing this kit with is a torque wrench. Since most bike bolts require a very specific torque, it's better to invest in one than to guess. But I digress.Overall, this tool set is decent. It can certainly get you off the ground and will likely pay for itself after a few repairs.
