If you've built your svelte road frame up with an equally sleek arrangement of matte carbon componentry, you might as well spring for Park Tool's Preset Torque Driver to avoid turning routine maintenance and quick adjustments into larger issues.

Must have if you have carbon bits...

I agree. This is an awesome tool. And essential to own if you have a carbon handlebar or seat post. And it is a better torque tool than the less expensive Ritchie ones. Solid and heavy in the hand. Really impressive. And very easy to use with a large handle. This wrench gives you great "feedback." A clear, definate and solid 'click' when you reach your torque limit. Great for properly tightening your stem and seatpost bolts.

Great to have!

I've put it through the wringer

Great for making sure that all your hexes are tightened down to the manufacturer's recommendation. Especially things on your carbon bars or your seat post clamp. Don't want it too tight! Super easy to use and swap out the different size bits. The extra bits are stored in the handle which makes it very compact and easy to store! This is a must-have for the home bike mechanic!

Gotta have it!

This is a must have for anyone who works on their own bikes. No need to stress about over tightening bolts, which can quickly lead to heartache and wallet-ache.


Can the torque setting be changed from the factory preset value

Hi Paul, The torque for this particular wrench will be set at either 4,5, or 6 nm. It can't be changed from the factory setting.

Small, convenient and accurate. What more do you need?

I've used it several times

In my time as a shop mechanic I came to appreciate the preset torque wrench. It is ready to go when you pick it up off the bench and is more economical than adjustable torque wrenches. Check your bike for the torque spec you need and remember that the posted spec is a maximum.

Best torque wrenches I've used

I've used it several times

I have two other traditional Park variable torque wrenches (high and low torque ranges), but I really like these fixed-torque drivers and use them most of the time. I have all three (4, 5, and 6). They are clearly labeled, make a obvious and clear "clack" when you tighten up to the torque value, are comfortable to hold, and it's really nice that it comes with the driver bits stored right in the handle so you don't have to hunt for them. I feel confident using them on carbon fiber components; there isn't much you can screw up. I think it's one of Park's best tools. I only wish they made them in higher torque values, but they would have to change the design so it used a longer handle. The only time I use my older TW-5 and TW-6 variable torque wrenches is if I have a higher torque setting. The older variable wrenches are a lot harder to set to the correct torque value because the scale is hard to read and not very precise. These are far superior.
