Park Tool Ratcheting Torque Wrench
Park ToolRatcheting Torque Wrench

The best investment.

As more and more parts and frames and wheels are made from carbon fiber, proper torque becomes even more important. While you could certainly crush or crack an aluminum or steel component, you had a pretty good idea what ‘too tight’ felt like. Carbon’s a bit different, and because of that, we advocate investing in a torque wrench like the Park Tool Ratcheting Torque Wrench. It works like your favorite socket wrench, but it clicks when you’ve reached the torque value you set it to, which keeps your bars, stem, pivots, seat collar, saddle rails, and just about everything else from cracking.

There is an updated version TW-5.2 and TW-6.2 for the same price. Are these the updated versions?

Hey Charles from what I am seeing on our end it looks like these are the TW 5 & 6 and not the updated TW 5.2 & 6.2

Park torque wrench

  • Familiarity: I've put it through the wringer

I use this torque wrench in the shop that I work at and at home and its the greatest thing ever. Accurately measures torque and has an audible click so you know not to go further.

Nice Tool for Home and Shop Mechanic

  • Familiarity: I've used it several times

I bought the TW-6. Actually received the TW-6.2 which is a newer version of the tool. The TW-6/TW-6.2 is a 3/8 drive click-type torque wrench suitable for use in higher torque applications such as Bottom Brackets, Cranksets, Pedal-to-Crankset, Center-Lock Disc Brake Rotors and Cassettes. The wrench reads and registers torque in both left had and right hand threading which is useful on pedals and Bottom Bracket. It comes in a nice hard case for safe storage and is reasonably well calibrated in both directions. Scale readings are in N-m and has a conversion scale to in-lb printed on the tool. Always store in the lowest torque setting to maintain tool calibration over a long lifetime. Here are some specs of the TW-6.2 from Park Tool:

- 10–60 Newton meter range (88–530 Inch Pounds)
- Adjustable in 0.25 Nm increments
- Ratcheting 3/8" drive
- Reads and registers for both left hand and right hand threading
- Dial-adjust system allows desired torque setting to be preset
- Calibrated to be accurate to +/- 4%
- Length: 36.2cm (14.25")

The TW-5 is the 1/4" drive version which is more useful on the rest of the bike (smaller torque settings).

Good carbon insurance

  • Familiarity: I've put it through the wringer

Whenever I question how tight a fastener should be, I grab this wrench out of my tool box. I feel pretty confident normally, but sometimes the accuracy of a mechanical measurement is just added insurance. Especially with how light carbon components are, the last thing you want to do is overtighten a stem and crack your $200 handlebar.

One thing to note, make sure to return the torque value slider to zero after each use. Park also recommends sending it back to them to have it re-calibrated, which is never a bad idea.

Cheap insurance

  • Familiarity: I've used it several times

At some point your bike obsession gets to the point that your bikes are worth more that your car/truck. When you have that much of an investment don't just guess, buy a torque wrench.

Don't crack your frame.

  • Familiarity: I've put it through the wringer

These hold calibration well when treated with care. Sometimes "hand tight" just wont cut it.

Better Than Cracked Carbon

    This is a great tool for a good price. You'll have to use your own bits, or buy park's separately. The wrench does not come with any. It does come in a great case and is very easy to use.

    Great tool

    • Familiarity: I've used it several times

    This is a must have if you do a lot of work on your own bike. Easy to use and comes with a nice hard case for storage.

    Great for the price, a must-have

    • Familiarity: I've put it through the wringer

    I've really enjoyed this torque wrench. It's a must-have for carbon bikes/parts. It's sturdy, easy to use, and comes in a nice portable case to protect the wrecnch. At first I was taken aback by the plastic handle but it has held up well and my initial concerns about durability are gone. It does not come with bits so you will need to buy those separately if you don't already have them. The 5-15nM is great for carbon handlebars, seatposts, and frame pivots. That's the one I bought and it's been perfect for everything I need on my bike. It seems to be accurate as far as I can tell.

    Apologies for seeking a reconfirmation. The picture shows it is a TW-6 but the specs stated is for TW-5. So which is it actually?

    Best Answer

    Sorry for the confusion! We carry both options. You are correct, photos are 6, description is 5. The dropdown will show both TW-5 and TW-6 granted that both are in stock. Hope that clears it up.

    Torque it!

    • Familiarity: I've put it through the wringer

    A must have in the day of carbon and light weight parts. Easy to adjust to the torque setting you need and easy to use to set the torque of your parts as you install the on your bike.

    You need this!

    • Familiarity: I've used it several times

    Don't crack your carbon bits! Park Tool makes it super easy for you to install components and torque them to spec. You get a very clear "click" letting you know that you've reached the torque setting. If you do any sort of work on your bike this is a must have.

    The pictures and cart options for this are for the TW-6, but the description/specs are for the TW-5, which one is it?

    Best Answer

    I confirmed it is the TW-6.

    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!

    TWS-6 Quickview

    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

      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.

      Park Explains Their Torque Wrench

      is this a low torque wrench (&lt;20ft-lbs)
      my soninlaw wants that kind of a torque wrench.

      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.
