VeloAngle Pro was developed for bike shops, manufacturers, fitters, race teams and individual enthusiasts that desire the convenience of an integral high-quality Digi-Pas 180s digital inclinometer.
For a limited time VeloAngle Pro purchasers will also receive a complementary 60 day trial licence to the VeloAngle App. Experience first-hand how well the App complements VeloAngle before making a licence purchase decision. Licence credentials will be forwarded by email.

Measuring devices such as scales and inclinometers have inherently high accuracy, but when assembled into a product, that accuracy can be degraded significantly. To prevent this, each VeloAngle is individually calibrated. The VeloAngle length scale is applied with the reference bores secured in a precision jig (left photo). Each saddle adapter end stop is individually scribed with a reference line for scale placement (right photo).
During calibration VeloAngle is pinned through the reference bores into ground blocks set on a granite surface plate leveled to within 0.25 mm/m (0.003 in/ft).
The following video is an example of the verification performed after final calibration. All readings must be within 0.1 degree of 0 and 90 deg.
While having an inherently accurate device is important, in many applications the accuracy and repeatability of how the device is used creates the majority of measurement uncertainty. For example, the most accurate scale in world won’t produce repeatable saddle to bottom bracket measurement when the placement of each end of the scale is dependent on the user’s judgement. VeloAngle solves this problem with unique adapters that find the bottom bracket and handlebar centers and allows the user to select and repeatedly find the spot on the saddle surface they want base their measurements.
Engineered bike measurement tools tend to rely on bubble levels that require the bike to be level to assure accurate measurement. The VeloAngle Pro inclinometer is equipped with an Alt-Zero button that can establish an alternative zero plane. This is particularly useful when the bike is in a stand or set on any uneven or non-level surface.
The genesis for developing VeloAngle was the belief that both cycling enthusiasts and those in the industry would respond positively to a device that had a better combination price, accuracy and convenience. We were particularly focused on convenience, as we know how much it influences purchasing decisions. It has sold over 30 billion K cups, despite the user often paying $40/lb for the coffee contained in them. While VeloAngle is not as convenient as pulling out a tape measure, every effort has been made to minimize the convenience penalty associated with its accuracy. Some examples:
