Must Have!

  • Familiarity: I've put it through the wringer

Torque wrenches are now a must have with the amount of carbon fiber that comes on most high end bikes. Torque specs are not just suggestions they are mandatory. Carbon will crack if not torque properly. Park tools has made it easy for us all to never over torque our carbon pieces. This torque wrench is simple and accurate. Must have!

Good tool to have....

This is one of those tools you may overlook, but once you have it, you wonder what you ever did without it. I have used this a bunch since I purchased it last month. So far I have used it on my shifters, brake levers, dropper seatpost lever, and cleats. It's nice to know I am torquing those items to manufacturer specs. I'd give it 5 stars, but it doesn't come with any attachements like different sized hex bits and such.

What's the difference bet Tw-6 and Tw-5?...

What's the difference bet Tw-6 and Tw-5? For my seat post, which one do I need?

Best Answer Responded on

The Tw-5 torques from 3-15 Newton Meters or 26 -132 inch pounds and has a 1/4 inch drive

The Tw-6 torques from 10-60 Newton Meter range or 88-530 Inch Pounds and has a 3/8 inch drive.

Most seatposts on carbon frames torque to 5NM, so the TW-5 is best.

I like the pedro's pro torque because it has a wider range (45 - 250 Inch-Pounds) the is better for home mechanics who can't afford both a 1/4 and 3/8 torque wrench.

is this a low torque wrench (<20ft-lbs)

my soninlaw wants that kind of a torque wrench.

Responded on

This is an ultra-low torque wrench that maxes out at 11ft/lb. Most bike bolts are measured in inch/pound or Newton meters (NM), 5NM is usually the minimum. This is a great wrench if you are tightening bolts on carbon frames, seat posts, stems, and bars. Outside that it is a bit of a specialty low-torque device in my opinion.

I recommend the Pedro's Pro Torque as a generic wrench (20 – 250 inch-lbs). It is less accurate but more practical.

If buying for yourself just by two cheap torque wrenches, a 1/4 inch and a 3.8.
