Handy little bike tool that makes handlebar, stem, seat post, etc. adjustments much faster and easier than pulling out and using the beam torque wrench (or guessing). Allows for quick adjustments regardless of what position your bike is in since you can feel and hear the 5Nm setting 'pop'. I used it to quickly assemble, adjust and re-tweak adjustments on a new alloy mountain bike and then, since I was on a roll, I checked over our carbon road bikes and found several bolts that were looser than they should have been. I do agree with another reviewer that the wrench is a little awkward to hold and twist in certain positions, possibly due to the twirl knob on the top, but it still rates 5 Stars IMO.
Note: Be sure to get this model with the four removable bits since Ritchey has a similar 5Nm model, for almost the same price, but with a non-removable M4 bit.
