The Topeak Ratchet Rocket Lite NTX+ has everything you need to fix and make precise adjustments to your bike while on the road. It features a fine-tooth ratchet mechanism with a reverse lever and thumb wheel, plus a TorqBit torque indicator for reading torque in tight spots. As you tighten, a hash mark on the bit holder moves from 0 along the torque scale on the collar (2-6 Nm, +/-10% accuracy). The TorqBit indicates torque; it does not click or stop at a preset value. Use it for tightening only, do not exceed 6 Nm, and do not use it to loosen bolts.
