If you mostly are just adjusting the cockpit and seat related items this is a good tool for that limited range or torque (although careful as many seatpost clamps recommend even lower than this tool in the 2nm range). If your doing lots of maintence better just pony up for a larger range wrench.
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.
