 Park Tool Tension Meter TM-1 is a COOL TOOL! November 30, 2009
M. Bennett (Outdoors)
Park Tool Tension Meter TM-1 is a COOL TOOL!
Ordered directly from Amazon and recieved quickly! Good Deal!
I strongly recommend this tool. It's sturdy, reliable and simple to use! The instructions are perfectly clear and not complicated. It takes less than 3 minutes to test each spoke in a 36 spoke wheel. Can be used on the bike, or off. The trouble of it is, that it's so easy to get your wheels to factory specs, it makes you think you know what you're doing:)
I cannot perceive why anyone would pay more for a spoke tension meter. There is a 40% leeway in adjustments, so splitting hairs is not necessary! (-20% to +20% of ideal tension)
I see talk on bicycle blogs about re-calibrating the tension meters, and meters costing $600! If you're not working for NASA or a scientific laboratory, don't be concerned with splitting hairs. This meter can be re-calibrated, but once you use it, you'll see that re-calibration will probably never be necessary.
Point of this report is that you will enjoy much less trouble (down time) because your wheels are factory strong at all times. Under-tensioned spokes cause spokes to break. One can have ALL SPOKES SOUND THE SAME and all spokes can be under-tensioned, so the 'sound technique' is not a valid way to judge true tension of your spokes! So I recommend that you don't go for the sound! Go for known specifications and your spokes will stop breaking!
I was paying a bicycle shop to replace the spokes on my mountain bike and I learned with this tool that the bicycle shop did not check the tension on my other spokes and that their work was a nightmare! No wonder the spokes kept breaking! Now, I ride the trails and my bike is in one piece at the end!
Do yourself a favor and get this tool! You'll be passing the guys on the trail that are limping back with broken spokes that use 'music notes' to tension their spokes! Let'em make music slowly, while you conquer the trail!

This tool will help you build evenly tensioned wheels. It is very quick and easy to use. I have not tried any other tensiometer but this one works fine. The tool itself is marked with a numeric scale. An included card shows the tension that corresponds to each number for a given spoke gauge. Once you determine the number you are shooting for you can test a spoke in a few seconds. There is an adjustable calibration screw but without a spoke of known tension you have no way to calibrate it. Using the factory setting the readings seem to be within the range I would expect when testing wheels built by expert wheel builders.

No More Guessing and Hopefully No More Broken Spokes May 7, 2009

The TM-1 Spoke Tension Meter works very well. I commute by bike every day to work, and among my three road bikes that I rotate through (set up differently for weather and load), was popping spokes to the tune of about 1 or 2 a month, mostly due to what I perceive to be overtorque on some of the spokes. Now I have torqued my spokes at the lower end of the recommended range and have yet to pop a spoke, and it is reassuring to know that they all are torqued to the same value. It does take a little bit of give and take to get the wheel trued, but with just a little bit of effort you can adjust the tension to the correct range, then make minor adjustments of individual spokes to get the wheel to spin true. You end up with a much more consistent torque range throughout the entire wheel, which eliminates overstress (hot spots) on overtorqued spokes.
Works great for building unicycle wheels March 16, 2009
Corbin Dunn (Los Gatos, CA, USA)
I've built two 36" unicycle wheels using this tension meter. It was easy to use and works great. I'm definitely not a professional, but it has given me a great wheel built that wouldn't have lasted as long if I did use a tension meter.
