Velogic Web Tools - Introduction

Velogic Web Tools is a powerful suite of professional online tools for bike fitters and bike enthusiasts.
Drawing on Velogic's own frame database of more than 30,000 individual frame geometries, Velogic Web Tools provides the most powerful set of lookup, search and utility functions available.
It's also free for enthusiast use; with some pro features available by subscription.

Getting started

Simply browse to If you don't have a subscription to the pro features, you'll see a "Sign in" link at the top of the page; but you can still use the tools without an account.
On the left-hand side of the screen (or under the top-left "hamburger menu" on mobile) you'll see a navigation bar listing the available tools:

Free vs paid web tools

Each of the Velogic Web Tools is available for free, with no login required. This is our way of giving back and supporting the bike enthusiast community.
There are a few features that require a subscription; these are pro-level features which are useful to professional bike fitters:
  1. Up to 30 search results in Advanced Search and Position Search (free users are limited to 8 search results)
  2. Ability to select and deselect search results, and download a PDF report of the selected options
  3. Specifying a set of "preferred brands", and a quick mechanism to add those to search queries
  4. Integration with our professional bike fit software, Velogic Studio


The remainder of this article gives a brief description of each tool, and when you would use it.

Home page

The Home Page provides quick navigation to new users of Velogic Web Tools.
If you're looking for details on a particular bike, the search bar on the left will take you to frame lookup for your search term.
If you don't have a particular bike in mind, the paragraph on the right has links and explanations to some of the most popular web tools.

Frame Lookup page

Frame Lookup page
The Frame Lookup page can be used to look up a particular model and year.
You can search by brand, model or year in the search box at top of the page. When you select a search result, the page will update to show:
  1. Basic properties for the model
  2. An image (if we have one)
  3. The geometry information for each size of that model.
If you click to select one of the size rows, you can jump to a range of other tools to explore this model further, or find other bikes with similar geometry.

Frame Configuration page

The Frame Configuration page allows you to:
  1. Search for a model (or, if you've arrived here from another page, the model will be preselected)
  2. Choose a frame size
  3. Choose a stem configuration (length, angle and spacers) 
... and the system will calculate the BarXY for you. 
This can be useful to find out the BarXY for your existing bike, before searching for other frames which could achieve a similar position (e.g. with Position Search)

Size Selector page

The Size Selector page starts with a frame search (or with the frame pre-set if you've arrived from a related page).
After showing the basic properties of the frame, you're asked to enter position information - most importantly, the BarX and BarY.
You can also choose to limit BarXY error (set to a small number to ensure you get very close to the desired position; or widen to allow more less-accurate results to be displayed)
If you enter a saddle height, the system will attempt to calculate how much the seat post "protrudes" out of the seat tube; you can also then specify a minimum saddle protrusion for the results. This is useful for shorter riders in an aggressive riding position, because their riding position might suggest a larger frame, but then the saddle needs to be slammed down onto the frame.

When you click "Suggest a size", the system will consider a range of stem configurations for each size of the selected frame model.
It will suggest the best model and configuration, and will also show all sizes ranked from "best" to "worst":

Note that the Rank (i.e. the sort order) attempts to balance two variables:
  1. How close that frame and stem configuration gets to the target BarXY
  2. How desirable the stem configuration is, given the size of the frame (generally a middle range of spacers and more common stem size/angle are considered more desirable)
In the example above, none of the options are great; they all have upturned stems (positive stem angle), which indicates that none of the sizes of this frame are perfect for the specified BarXY. The best option is the size L; it only has a +6 degree stem, the BarX is only 7mm longer than the target, and the barY is only 7mm short of the target.

You can also click on any of the results to see a range of other stem configuration options for that size:

Position Estimator page

The Position Estimator page starts by asking some multi-choice questions about how you ride, and then asks for some measurements of your body.

You can click the information buttons next to the measurement fields to see more detail on how they should be measured.
After entering measurements and clicking "Estimate position", the system will estimate a riding position:

Note that the system is making many assumptions to arrive at those results. You shouldn't rely heavily on them; you certainly shouldn't make any purchase decisions based solely off this tool!
You can jump to the Position Search page or Size Selector page to find suggestions for bike models and/or sizes that would work for that position.
If you're a bike fitter, you can also use the BarXY as a starting point for the fit, if the customer doesn't already have a bike you can measure. 

Position Search page

The Position Search page lets you search across our entire frame database for a bike model + size + stem configuration which will achieve the target barXY position.

The "Your position" area lets you specify the target position. This is the same as the Size Selector page; refer to that section (above) for more information on that (and/or click the information buttons next to each field)
The "Bike criteria" area lets you add criteria that each search result must meet. You can use the "Quick add" links to specify a discipline (Road, Mountain bike etc), and specify that the model year of the result should be in the last 2 years.

Note that you can search by a wide range of criteria here; essentially any property of the frame or geometry. Click the "Select a field" dropdown to see the list of available fields:

Once you've specified the conditions for the search, click the Search button. The system will search across all frames in our database, and show you a range of frame

At this point, the experience is slightly different depending on whether you're a "free" user, or whether you have a subscription to the Pro features of Velogic Web Tools.
The Pro features are:
  1. 30 search results (rather than 8)
  2. Ability to select and deselect results
  3. Ability to download a professional PDF report with the selected results.
The Cards view shows the same results as the Grid, but includes more information for each, including an image of the frame:

If you have a subscription, you'll also see the "Download report" button at the bottom of the grid and the card views. Here's an example of the first page of the PDF report:
Sample PDF report page
Note the QR codes on the report. The QR code for each bike links to that bike in Frame Configuration page; the QR code in the right margin links back to the same search that generates the report. As a bike fitter, you can give this report to your client to allow them to explore the database themselves, after the fit session.

Advanced Search page

The Advanced Search page is similar to the Position Search page (see above). The main difference is that it doesn't ask for a BarXY, and therefore doesn't attempt to find a stem configuration; it's more of a direct database search.
The Advanced Search is most useful if you want to search by geometry, e.g Frame XY (a.k.a Frame Stack and Reach). It's also useful to find triathlon/TT bikes, because the Position Search doesn't (currently) work with aerobars.
You can enter a range of search criteria, or allow them to be auto-populated for you if you're coming into this page from (e.g. from Frame Lookup, if you're trying to find a bike with similar geometry to your existing bike).

When you click "Search", the system will present you with bikes matching your criteria (if any). 
Similar to Position Search, the experience with the results depends on whether you're subscribed to the Pro features of Velogic Web Tools. Either way, you'll see a set of "cards" with details of each search result.
All of the sizes for each result are listed, but the specific sizes which match your criteria have a dark border. 

You can click on the title of each result, or on any of the sizes, to jump to the Frame Lookup page for that result.
If you're subscribed for Pro features, you can also download a report:
Advanced Search PDF report
This report is similar to the Position Report (from the Position Search page), but instead of stem configuration, the report has general frame information for each search result. Only the sizes of frame which match the search criteria are listed in the "Size" field for each result; there may be multiple sizes for each model, depending on your criteria.
