I recently got the
Bike Torque Wrench Set - 1 to 25 Nm – 1/4 Inch Driver Pro MTB Bicycle Maintenance Torque Wrench Kit Tool for Road Mountain Bikes Motorcycle Multitool, on Amazon made by a Chinese company, Homelae. I paid $48.00 for the torque wrench because the range is 1 to 25 Nm and reasonable price with 5 star rating. I am still learning how to use it and will keep you posted as I work with an experienced bike mechanic. With a range of 1 to 25 Nm most bolts are covered. You could get a torque wrench made by Park Tool or Pro Bike Tool and spend a lot more but I believe they all come from China. It arrives with a certificate that it is pre-calibrated with a guaranteed accuracy of +/-4%.
