I have never had a problem with over/under tightening bolts. With the newer carbon components, I did not want to take any chances with over tightening, so I purchased this. Works within the range needed for handlebars, stems and seatposts. Once you reach the torque setting that you select, the wrench will simply slip no matter how much you turn it. I find this much better than the click type of torque wrenches. Because it takes standard bits, I was able to use bits and an extension from one of my screwdriver multi-tools. Overall it is quick, simple and effective. Get one.
I was always told that having a torque wrench was not enough. You need an accurate torque wrench. I went with the safe option and chose Park Tool. The tool is really sturdy, on the heavy side. Gives me a lot of confidence when working on my carbon parts. Make sure you remember to not rotate counter clockwise.
It's a great product to use to torque bike bolts at home or in the shop. It's easy to operate and efficient. However, I don't like it's torque range of 4 to 6 Nm. And because of this I don't take it on bicycle trips with me. A wider range of 2 to 16 Nm would be better but those type of torque tools are far more expensive.
Had I done more research I might have bought s rachet for the same price will a wider range of torque settings, nevertheless this is an excellent compact torque driver. I would easier travel with this out of town and have a rachet at home. Highly recommended.
I bought this tool for a trip were I shipped my mountain bike and had to assemble it at the destination. I only then realized how simple and effective this tool is - much better than the other torque wrench I already had. Highly recommended and easy to use. You have to take a hex key to adjust the torque setting - but that is not a bid deal. With such a tool there is no excuse to not tighten to the correct torque.
ParkTools are the SnapOn of bicycle tools. I've always used my ip torque wrench and this T-handle adjustable torqe wrench is so much more convenient. It fits in tighter places better. I keep it in my pocket or on the tool stand for working on my bicycles. Love it!
A bit pricey but it makes it easy to make sure small bolts are tightened up correctly without having to break out the regular size torque wrench. Use it in my stem and seatpost bolts. Positive click and feel so there is no mistaking that its tightened correctly. Easy to set and use. Cheaper than buying a regular torque wrench if you only need it for lower torque items.
I used the Park Adjustable torque drive to install a Red shift shock stop stem on two bikes, and to install new disc break rotors. Its nice to know that my installations were done correctly and the tool just feels good in my hand- quality tool.
