Optimizing spoke tension is the key to building long lasting wheels. Tensiometers make this possible and you have quite a choice in the market today.
Wheel Fanatyk Digital Tensiometers are among the most accurate, durable, convenient, simple, and logical available. A breakthrough vision by HP engineer Jobst Brandt in the 1970’s created a tool format that stands the test of time.
Wheel Fanatyk’s version is the evolution of Jobst’s original design, made to ever-higher tolerances, employing super accurate indicators, and optional SPC cable for direct output from the digital model to a computer’s spreadsheet.
Please check our numerous posts about the tool’s details and care. You can view a movie of the tool in use and download the Owner’s Manual for reference. It comes calibrated for spokes between the thinnest aero to 4mm thick Ksyrium aluminum, including 13g and 12g.
From 2009 to 2011, we sold a since-discontinued model by FSA. From 2011 we sold the Classic digital model. In those 7 years over 500 tools sold without a single return. Beginning Oct 2015 we switched to Mitutoyo indicators, one analog (dial) and one digital.
- Compact design, easy to handle, the gauge is protected from damage or becoming entangled in spokes.
- Less expensive than similar gauges.
- Wheel Fanatyk is significantly more accurate at low tensions, such as found recently on the left sides of 11 speed road wheels.
- The tool is offered in a shock proof, foam lined, hinged case; with a 26 page Owner’s Manual; a laminated Tension Chart (for gauge reading conversion); and a memory stick with supporting materials.
All come with a 1-year warranty and lifetime recalibration privilege.
The tensiometers are US made except the indicator. Mitutoyo has been chosen for world class quality, accuracy, and ruggedness. Since 1934, Mitutoyo has become a backbone of scientific and manufacturing QC. Each tensiometer is individually numbered and tested.
The rest of the tool is machined in the Northwest by small shops. Load is applied by a calibrated Lee Spring. Founded in Brooklyn in 1918 by Robert Johannsen, Lee is a global, ISO certified, spring specialist. I personally build and calibrate each tool.
Please see our Library for articles and a movie describing its use.
The digital model can output data with dedicated cable. Check here.
