Feedback Sports chain gauge

Essentially a modified digital calliper, Feedback Sports' Chain Gauge eliminates the guesswork when determining chain wear. Compared to a metal chain checker or steel ruler, you're less likely to get errors due to you making a mistake, or tool wear. Being digital it's more expensive, so it will probably appeal to bike shop mechanics more than home mechanics.

To check the chain, you hook the calliper's crescent end in first, and then slot in the other end eight links apart. The reading is broadcast on the display in either metric or imperial. Figures from 0.00 and 0.40mm denote a fresh chain, 0.40-0.80mm a chain with some wear, and .80mm or more a chain that needs replacing.

A small brass screw can lock the arms, saving the reading for later inspection. This is useful if you're measuring the chain with your bike on the floor rather than at eye level, as the display's flat face is awkward to read unless you're looking at it side on. It could also be useful in a shop setting, to show the extent of the chain wear to a customer standing at the counter.

The display cuts out after five minutes of inactivity to conserve battery life. You get a spare 1.5V watch battery with the gauge, along with a carry case, a jeweller's screwdriver, and a set of instructions. The latter are pretty simple but thoughtfully there's a chain wear tolerance chart on the back of the tool itself.

The instructions suggest re-setting the unit every 30 readings for absolute accuracy. I didn't have a checked and calibrated control model for comparison, so can't be sure just how accurate the gauge is. I hit the reset button and used a factory-fresh 8-speed chain on my Univega as a yardstick. The gauge returned 0.01mm readings at three different points, so I measured the chains on my other bikes in the same way, confident to accept the gauge's readings at face value and replace chains accordingly. After using it a few times, checking chains becomes intuitive.

Verdict

A precision tool that will repay the investment many times over. Its display would be easier to read on the top rather than the side

Tell us how the product performed overall when used for its designed purpose

Intuitive after a few practice runs, readouts have been consistent and seemingly reliable. The ability to save readings by turning the brass screw is a godsend since the flat positioning makes figures tricky to determine in situ.

Tell us what you particularly liked about the product

Simple to use and takes the guesswork out of determining chain health.

Tell us what you particularly disliked about the product

Poor ergonomics of the display

Did you enjoy using the product? Yes

Would you consider buying the product? Possibly.

Would you recommend the product to a friend? Yes, assuming they had a big fleet or bike(s) with high end, sensitive components.

Overall rating: 7/10

Surely you'd expect it to tell you if it is too stretched to use rather than just measuring the distance and allow you to work it out?

What, it just displays the length on a screen? Doesn't it tweet your measurements, sync with your Garmin, and update your Facebook wall as well? And the price - only 50 quid - I want to spend at least a three-figure sum, otherwise what is there to brag about. Lame.
