Covers all the torque specs on a shimano ultegra equipped bike (14 nm high end for the crank arms). Other brands of components have higher torque settings so verify you donï¿½t need the larger TW-6.2 before ordering.
Have gone by feel in the past with tightening bolts, but since having carbon components on an alloy bike, I've been using this more and more for routine adjustments and maintenance, even for non-carbon components as well. Very useful torque range. I did get a torque wrench with bigger range, but rarely ever use that one since those parts (crankset mainly) don't need that much adjustment.
Torque click feedback is good, micrometer adjustment is good. Stated accuracy is most useful mid range to top range. If the torque is less than 2Nm or something small, I just hand tighten with an allen wrench.
This relatively small tool does a good job torquing bolts up to 14NM which accounts for nearly every specification related to carbon fiber. The small head comes in handy when working in tight spaces. I trust Park tools.
