3m/10ft Tape Measure

A metric tape measure is harder to source in the US than it should be. Most hardware-store tapes read in feet and inches first, with a metric scale shrunk to the bottom edge; useful enough until you need to read a 1-millimeter increment on a fork's recommended axle-to-crown spec, and the millimeter marks are crowded against the imperial half-inches. The 710R-US is Unior's 3 m / 10 ft dual-scale tape: the official table lists 3 metres and 10 feet on the same article, code 625129.

The tape is 3 meters / 10 feet long. That's the length you need for measuring frame reach (the longer the reach, the more critical a metal tape), wheel diameter (a 700c wheel measures around 670 mm at the bead seat), bar widths (a wide gravel bar is 480-500 mm), and most of the dimensional checks a working shop does on a daily basis. A shorter pocket tape covers bar width and small checks but stops short of frame-geometry work.

When you'll reach for the tape and not the caliper

The caliper handles fine measurements at small ranges. The tape handles coarser measurements at long ranges. Both are necessary; neither replaces the other.

Tape work: bar width, frame reach, wheel circumference for cyclo-computer calibration, stand height when assembling a customer's bike for size, the distance between two bolts that need to be at a specific spacing.

Caliper work: rotor thickness, axle outer diameter, head tube inner diameter, spacer thickness, anything where 0.01 mm matters. See our digital or analog vernier caliper.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The 710R-US is one of the small workshop fundamentals Unior catalogs alongside its bike-specific tools. A metric tape measure is a working-shop staple in any country that runs on metric measurements; it's a niche find in the US, which is why we stock it for US shops working on European-built bikes.

Pro tip from our mechanics

The single most-overlooked tape-measure use in a bike shop is calibrating a cyclo-computer's wheel circumference for a specific tire. The published spec for a tire is approximate; the actual rollout (mounted, inflated, with the rider's weight) is what the computer needs. Rolling the wheel one full revolution and measuring the distance traveled with the tape is the right answer.

FAQ

How long is the 710R-US tape? Official length is 3 m / 10 ft. The face label prints 3m/10ft. Code 625129. Unior's 710R family also has other lengths; this US article is the 3 m / 10 ft dual-scale SKU.

Does it read metric and imperial? Yes. The official 710R-US table publishes both a 3 metre column and a 10 foot column on the same article. The EU 710R page also lists metric-only SKUs (3 m with 0 ft); those are not this product.

What does class II mean on this tape? Unior rates the 710R-US 'preciseness to class II' and marks the blade with a circled II, a CE mark, and a 20 °C working-temperature mark. The product page does not publish a millimetre tolerance table for that class.

How big is the case, and what ships in the box? Plastic double component case with a stop and clip, metal tape. Official diameter 16 mm, weight 89 g (tolerances apply). Article 710R-US, EAN 3838909251295. It ships as one tape. Unior lists no spare parts for it.
