What Customers Think of VeloAngle

"Thanks for your reply and the e mail you sent as well. I am really loving having this tool. I've documented the fit of all my bikes now"
James H., Washington

"Many thanks for creating such an accurate and easy to use measuring device. I'll continue to tag and support VeloAngle in our social media posts."
Adrian Spinelli, Perth Bike Fit, 

“Thanks Dave for the update. Appreciate your courtesy and customer service. Glad to to business with you!!"
Harald S., New Zealand

“ VeloAngle has greatly improved our accuracy measuring and recording a cyclist’s position. Compared to traditional methods that rely on gravity and the accuracy of an individual’s sight line, VeloAngle is an absolute game changer. “
Brian McGuigan, Ciclo Sudore, Florida

“I purchased the VeloAngle Pro version this summer and I love it. Thanks!” 
Maxime V., Canada

“VeloAngle has made my life much easier. I use it to setup all my son’s (U23 pro) bikes and to match positioning for my bikes. It is the first time ever that I have had two bikes that I could not tell which bike I was on if I was sitting on the trainer blindfolded.”
Eric S, California

“I wanted to follow up. I finished my CAAD12 build and your product really helped with setup and fit as I originally expected. I admit I was intimidated at first once I opened up the package (excellent packaging BTW!). Brilliant idea and from one cyclist to another. I’m glad you invented it! Every cyclist needs this product.“
Tom H, Michigan

I've answered my own question by logging into the app, fantastic tool you have here!
Ian L, Florida

“Thanks for the speedy responses, Dave! I really enjoy working with the VeloAngle. Your product helps me save time and money.”
Herman U, Nevada

“VeloAngle absolutely exceeded my expectations terms of ease of use and the precision with which I'm able to replicate my contact points across bikes. One benefit of the tool that I didn't anticipate but enjoy, is it gives me much more freedom and confidence to test small changes in my bike position, knowing that with the VeloAngle I'll be able to easily revert to my former position. When I had a question, I got a prompt response from the company. I'm a very happy customer!“
Joshua S, California

“VeloAngle allows for a quick method of making and verifying required changes, like saddle height and stem length. I find the App that graphically displays the measurements to be very helpful, especially when comparing different bikes.“
Gary B, Michigan

“Lovely device and well thought out.”
Stephan B, United Kingdom


  • VeloAngle’s primary application is to define the relative position of the bottom bracket, saddle and handlebars. Bikes with aerobars or integrated handlebars require the optional Saddle-Handlebar Adapter for measuring handlebar location.

  • Optional VeloAngle accessories further expand its capability (see Shop/Accessories).

  • The VeloAngle App is a valuable companion to document all measurements, provide visual comparison of the relative position of each setup and convert measurements between X-Y and Polar coordinates. A slide show and link to can be found on the home page


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 are 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:

  • Retracts to 25.7” x 3.5” x 1.5” (653 x 89 x 38 mm)
  • Can be used on both the left and right side of the bike
  • Can be used upside down to gain better access
  • The tips of the nibs protruding from the end housings also contain flats aligned with the reference bores. These features permit the use of VeloAngle for taking “freehand” measurements of various features nearly as quickly as with a tape measure but with much greater accuracy.
  • The method of maintaining the alignment of the two telescoping tool sections was chosen in part because the central slot provided a convent means of aligning the tool with features like frame tubes, seat posts and seat clamps.
  • The straps on the Saddle Adapter and Handlebar Adapter are removable if the users decides they don’t want to utilize them or they purchase the optional fixed pin adapters that eliminate the need.
  • To provide convenient and efficient storage, the shipping inserts are reusable and engineered as an organizer to hold VeloAngle and all available accessories in the original 4” x 4” x 28” box.
