TopeakRatchet Rocket Lite DX Bike Repair and Maintenance Tool, 16 Functions, Includes Nylon Bag, Black

This is truly a must have when riding a bike in the middle of nowhere. When a screw gets loose or you need to tighten a bolt, this is handy to have. Lightweight and small enough to store on the bike or in a bookbag. Definitly recommend!

My buddy was very happy with the strength of the bits.

This toolkit has all the necessary tools you need for basic maintenance and repairs to your bike. It compact but fully functional and efficient.

This tool is undoubtedly awesome. It is tiny yet strong, and I have used it for a multitude of non-bike repair tasks as well with no issues or breakage. Of course I'm not asking it to do the job of a 3/8" ratchet, but it is strong enough for all kinds of small jobs. I usually find myself using it for repair tasks where a larger tool won't fit (which is surprisingly common), but I also use it plenty for small fixture or bolt tightening when I'm on the go and no other tool is readily available.My one complaint is that the included holster starts dropping bits randomly after a couple years of wearing it. I think what's happening is that the elastic band is loosening up over time as the rubber inside it deteriorates.

This little set is small and light, but is so useful. I’m going to buy a few more to go on my other bikes.

Very high quality materials. I purchased one set for each bike I own. Best toolset I've had in the last 14 years

I bought this ratchet because I wanted something I could throw in a bag and never need to worry about having the right tool - and it does this perfectly. It doesn’t come with a ton of bits but it has basically everything you need for bike repairs or a quick electronic disassembly, and you could swap out some of the less used bits for a PH0 and a small slotted bit for a few dollars at the hardware store. The bit holder in the end of the ratchet means you can pretty safely replace the bit extender with a small pair of pliers or a pen knife as well.Is this kit worth it as-is? Yeah, absolutely - but if you’re looking for the perfect toolkit for your handbag or back pocket, this is as good a start as you can get.

A friend of mine had a set like this. I used his several times and liked it. These are lightweight the fit is great and very versatile.
