Park TM-1 Spoke Tension Meter

StarStarStarStarStar 4.9 of 5 stars average ( 8 reviews )
The key to wheels that are strong and reliable is having spokes that are properly and uniformly tensioned. The TM-1 Tension Meter accurately and reliably measures the absolute tension of each of the spokes in a wheel, as well as the relative tension between all the spokes in a wheel. Easy to use and priced affordably, the TM-1 works on nearly any bicycle spoke-no matter what the diameter, material, or shape. Not just for the experienced mechanic, the TM-1 is for anyone building or truing wheels, diagnosing wheel problems, or assembling new bikes. It's a tool that belongs on every workbench.

Customer reviews of this product:

StarStarStarStarStar This tool will roll you straight.

by
Product: Park TM-1 Spoke Tension Meter
Ownership: a few months
Tech Knowledge: somewhat high

Pros

Know the tension of your spokes while building a wheel.

Cons

They say measure twice. Cut once. Well, I don't know how much measuring I did with this thing to rebuild my wheel, but I was ready to just put the thing on my bike and ride already. Lots of measuring.

Other Thoughts

When you use park tools online graph after getting the wheel trued up, you see the differences in tension. It's amazing how much you can even it up just by knowing where to start. The graph is useful.

I have rebuilt 2 wheels with this tool. I built one before getting it.

Product: Park TM-1 Spoke Tension Meter
Ownership: a few months
Tech Knowledge: average

Pros

Easy to use. Seems to give consistent readings.

Cons

Requires judgment in reading between the lines--but that is probably insignificant to the overall project.

Other Thoughts

I am glad that I invested in this tool to build my first set of wheels. I found the idea of spoke tension to be difficult to grasp in general, so it was nice to have a tool to provide a benchmark.

StarStarStarStarStar Amateur Wheelbuilding with Park TM-1

Product: Park TM-1 Spoke Tension Meter
Ownership: more than a year
Tech Knowledge: somewhat high

Pros

Simple and sturdy construction (no glass or dial gauges).
Easy to use.
Attractive anodized finish.
Bought on sale (reasonable normal price).
Made in USA.
Cool addition to the tool box!

Cons

Requires conversion table to obtain tension.
Looks less high-tech without a dial gauge.

Other Thoughts

I had built a couple 20" wheels for my folding commuter bike before I built a rear wheel for my full-size road bike. I found the TM-1 on sale, and took the plunge. I was easily able to build a dished wheel and, using the tool, get the tension of all the spokes to within 10% of the mean tension. The wheel has remained true with no spoke loosening or breakage. After this, I built a 20" wheel and had the same result.
I am a "quantitative" sort of person, and tightening spokes by tapping just didn't seem as satisfactory; I use a torque wrench on bolts, so why not measure tension on spokes?
No regrets about the purchase!
