Privacy Policy
Last updated: 6 October 2026
This policy explains how personal data is processed when you use the Bike Configurator, a RockIT Tools project, at road-tt-configurator.web.app.
The controller determines the purposes of processing. You can use the email address above to ask a privacy question or exercise your rights.
2. Using the configurator
Frame, paint, wheel and groupset selections are processed in your browser. The application keeps these selections in working memory, not in an account or a server-side configuration database. Reloading the page resets them. The site has no registration, checkout, newsletter, uploads or location request.
Photographs, page files and scripts are downloaded so the tool can display your selection. This creates ordinary requests to the hosting provider; requested image filenames can reveal which product image is being loaded. Configuration choices are not sent as analytics events.
3. Hosting and technical requests
The website is served through Google Firebase Hosting. Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA, and its relevant service affiliates process technical request data to deliver and protect the service. Requests can include an IP address, time, requested URL, browser information and a referrer, depending on the browser.
The purpose is delivery, reliability and abuse prevention. The legal basis is Article 6(1)(f) GDPR: the legitimate interest in providing a secure, functioning website. Firebase states that Hosting retains IP data for a few months. Provider-managed retention is described in Firebase's privacy and security information.
4. Firebase SDK, storage and cookies
The configurator also loads the Firebase App SDK from Google's www.gstatic.com service to initialize the site's Firebase configuration. The download exposes ordinary technical connection information to Google. Automatic data collection is disabled in this site's Firebase App initialization. No Authentication, Firestore, Realtime Database, Analytics, Performance Monitoring or advertising SDK is used by the configurator.
The configurator does not set advertising cookies or store your bike selections in localStorage, sessionStorage or IndexedDB. The consent service described below may store a record of your privacy choices. Your browser can cache downloaded files as part of normal website delivery. This is different from storing a bike configuration or using advertising identifiers.
5. Advertising and consent
Current status: this version does not load advertising or analytics scripts. The AdSense publisher verification tag and ads.txt entry identify the publisher; they do not themselves serve ads or place advertising cookies.
Managing your privacy choices
The online configurator integrates Google's Privacy & messaging consent service (Google's certified consent management platform, or CMP) using the IAB Transparency and Consent Framework. The service is requested from fundingchoicesmessages.google.com. Google receives technical connection information such as your IP address, browser information and the website address, and uses the request to determine which published consent message applies to your visit. Banner availability depends on the site's AdSense message configuration and your region. The downloaded, local HTML version does not request this service.
Where a message is available, it lists the relevant purposes, advertising providers and their information and lets you accept, refuse or manage optional processing. Google may save your selection and the associated consent record in cookies or other browser storage to remember and apply your choices. Consent-record storage is used to maintain your choice, not to save your bike configuration. The purpose of the technical consent service is to present, record and respect privacy choices. The legal basis for this technical processing is Article 6(1)(f) GDPR, the legitimate interest in operating and maintaining privacy controls; strictly necessary consent-record storage is subject to Section 25(2) TDDDG.
Use Privacy & cookie settings, also available in the footer, to reopen an available Google consent message and change or withdraw your selection. Refusing optional processing does not prevent use of the configurator. If the service is unavailable or no message applies to your visit, the settings explain this and advertising remains disabled. This privacy page and the other information pages do not load the consent service or advertising scripts.
The service's current message and provider information explain the selected purposes and applicable storage durations. Records can remain in your browser until their expiry, replacement or removal. You can also delete site cookies and storage using your browser's settings; this may cause the consent service to ask for your choice again. A consent record is not an instruction to activate advertising on this version of the website.
Information about Google AdSense
If Google AdSense is enabled later, Google and third-party advertising partners may place or read cookies, use web beacons, process IP addresses or other identifiers, and use previous visits to this or other websites to select, personalize and measure advertising. Google's advertising cookies can allow Google and its partners to show ads based on those visits.
Consent-dependent advertising must remain blocked until the CMP has received the required permission. Optional storage and consent-based processing rely on Section 25(1) TDDDG and Article 6(1)(a) GDPR. Advertising and analytics are disabled in this version, including after a consent choice; accepting a consent message does not itself load advertisements. The privacy information, actual partners, retention details and consent-dependent loading must be reviewed before advertising is activated.
If you email the operator, your email address, the contents of your message and any information you include are processed to answer the request. The mailbox is provided through Google Gmail; the site itself has no contact form. For a general inquiry, the legal basis is Article 6(1)(f) GDPR, the legitimate interest in responding to correspondence. Where an inquiry concerns a contract, Article 6(1)(b) GDPR may apply.
Correspondence is kept as long as needed to handle the request and, where applicable, to meet legal retention duties or establish, exercise or defend legal claims. It is then erased. Please avoid sending unnecessary sensitive information.
7. Recipients and international processing
Google receives the technical information necessary for hosting, SDK delivery and the consent service and, when you send an email, the information handled by its email service. Data may be processed outside the EEA, including in the United States. Google's Firebase privacy information describes its EU–U.S. Data Privacy Framework certification and relevant international processing arrangements; Google's data transfer frameworks and its applicable service terms provide further information.
External manufacturer, retailer and reference links are opened only when you follow them. Those sites process data under their own privacy policies. Their images are served from this website's hosting rather than fetched directly from a retailer when you select a bike.
8. Your rights
Subject to the requirements of the GDPR, you have rights to access, rectification, erasure, restriction of processing and data portability. You may object to processing based on legitimate interests for reasons relating to your particular situation. Where processing is based on consent, you may withdraw it at any time without affecting the lawfulness of earlier processing.
You are not required to create an account or provide contact information to use this tool. Technical connection data is necessary to deliver the site. This application does not make automated decisions about you with legal or similarly significant effects and does not create advertising profiles in its current version.
This policy will be revised when the site's functionality or data processing changes. The date above identifies the current version.
About the configurator
By Jan Rockrohr · Last updated: 6 October 2026
The Bike Configurator is a free RockIT Tools project for exploring a road or time trial build. It brings the frame photograph, factory paint finishes, wheel selection, rim depths, groupset comparison and estimated complete-bike weight into one view.
What you can compare
The catalogue includes road and TT / triathlon models from Canyon, Cervélo, Orbea, Colnago, Trek and Factor. Paint choices use photographs of the finishes in the catalogue. Wheel options cover DT Swiss ARC DICUT, ENVE SES and Zipp NSW, including a front-wheel / rear-disc combination. Front and rear rim depths can differ; the depth picker shows the pair.
How the preview works
Rather than recolouring a generic drawing, the preview combines photographic layers. The frame photograph is aligned using its wheel centres and tyre radius. Separate wheel photographs are positioned at those centres, beneath a mask that keeps the fork, stays, drivetrain and tyres in front where appropriate.
All bikes use a common visual wheel scale so you can compare their appearance. This is a normalized preview, not a dimensioned frame-size drawing. Small differences in camera angle, lighting and the photographed build remain visible. A photographic composite cannot demonstrate clearances or the precise look of a finished workshop build.
Sources and corrections
Manufacturer specifications and identified component references support the frame and wheel figures. Groupset masses are rounded complete-kit estimates, rather than manufacturer-published totals. The product-source links under the configurator and the weight details identify the models, photographs and measurement assumptions. The guide explains how to read these figures.
Where a complete-bike reference is available, wheel and groupset selections replace their reference masses while retaining the remaining build. Otherwise, the tool adds frame, wheel and groupset references to explicitly estimated other components. Unpublished frame or factory-wheel masses are marked as assumptions in the breakdown. Paint-related mass differences are not measured by this tool.
If a source changes, an image represents a different generation, or you find an alignment problem, please send a correction with the model, paint and wheel choice. The catalogue is a selected set of references, not a promise that every product or paint is currently available for purchase.
Use conditions
The site provides visual comparisons and reference estimates. It does not sell products, reserve stock, give a binding price, certify aerodynamic performance or approve component compatibility. Before buying or assembling a bike, check the exact frame size, tyre and rim combination, hub dimensions, cassette body, brake interfaces and clearances with the manufacturer or a qualified bike shop.
Weights vary with size, finish, groupset, fitted equipment and the manufacturer's measurement basis. The displayed complete-bike estimate excludes pedals and does not include the rider, luggage, tools or drinks. A scale measurement of the actual build is the way to establish its actual mass.
The tool and guides are maintained independently by Jan Rockrohr. Brand names identify the products being compared and do not imply manufacturer affiliation or endorsement. Original explanatory text is provided for reading and using this tool; third-party product photographs and trademarks retain their respective owners' rights.

Include the frame model, paint name, wheel series and rim-depth choice, plus what you expected to see. If a specification is incorrect, include a link to the exact manufacturer's model or a measured reference. This makes it possible to distinguish a different hub, size or product generation from a catalogue error.

A practical guide to your build
By Jan Rockrohr · Last updated: 6 October 2026
A wheel change affects both the appearance of a bike and the mass of its build. This guide explains what the configurator shows, how to compare a pair of rim depths, and what you still need to check before turning a photographic preview into a real bicycle.
1. Start with a frame and its actual paint
Choose Road or TT / Triathlon at the top. The frame selector shows the active model in the middle, with neighbouring choices above and below. Scroll over the selector, use its arrows, swipe vertically on a touch screen or use the keyboard arrow keys while the selector is focused.
The paint dots select the factory-finish photographs included for that model. Read the paint name under the preview: similar white, black or metallic finishes can have different names and graphics. These are photographed references, not arbitrary colour overlays. The available models are:
The common wheel scale keeps each bicycle centred and makes visual changes easier to compare. It does not mean the frames have identical geometry or that the image represents your frame size. Frame sizing and riding position need their own check.
2. Choose the wheel series, then the depth
The Wheels selector chooses Original factory, DT Swiss ARC DICUT, ENVE SES or Zipp NSW. The separate Depth selector chooses a photographed option within that series. It remembers the selected option when you switch between wheel series.
A pair such as 50 / 56 mm means a 50 mm front rim and a 56 mm rear rim. These numbers describe rim depth, not tyre width, wheel diameter or frame clearance. A single number means the two reference rims have the same nominal depth. The original factory pair has one fixed setting, so its depth arrows are inactive.
Disc describes the solid rear wheel in the Zipp 454 + Super-9 combination. It does not mean a different brake type. The front remains a 58 mm Zipp 454 NSW. The preview is a way to inspect that combination's appearance; it is not a recommendation for every course or weather condition.
3. Wheel options in this catalogue
The table lists the selected published wheel references used by the tool. Masses refer to the pair, with the tape, valve and accessory basis explained in the weight details. Those bases differ between references, so a small numerical difference is not necessarily a like-for-like measurement.
DT Swiss entries use the specified factory front/rear article references; a photographed used pair may have a different production specification. ENVE entries use the identified INNERDRIVE wheelset weight tables. The Zipp disc combination uses separate front and rear references. Follow the links and match the exact hub and freehub version before comparing a product you plan to buy.
4. Compare mechanical and electronic groupsets
The Groupset dial contains 24 Shimano and SRAM road and drop-bar references, sorted from the lightest estimated kit to the heaviest. Use scrolling, the arrows, a vertical swipe or the keyboard as with the other selectors. The active choice shows its shifting type, number of chainrings and rear speeds, generation and estimated mass. It updates the weight while the central photograph keeps its photographed drivetrain.
Shimano's electronic choices are labelled Di2; SRAM's are labelled AXS. Mechanical options cover the corresponding road families and entry-level groups. Legacy identifies older generations, including mechanical Dura-Ace and Ultegra and SRAM 22 and 1 families. There are no invented electronic variants of Sora, Claris or Tiagra. This is a selected road catalogue, not a list of every historical or mountain-bike group.
The rounded groupset estimate includes controls, derailleurs, crankset and chainrings, cassette, chain, bottom bracket and reference brakes. Disc-kit references also allow for rotors, and electronic references allow for batteries and shift wiring. Pedals, chargers and power meters are excluded. Gearing, crank length, hoses and TT controls affect a real kit's mass. Product and photo links below identify the reference, not a verified manufacturer total.
The number below the preview is an estimated complete-bike weight without pedals. Open Weight breakdown underneath it to see Frame, Wheels, Groupset and Other components. Those four rows add to the complete-bike total. Click the main weight for further references and assumptions.
For a model with a published complete build, the calculation is: reference complete bike minus original wheelset plus selected wheelset, minus reference groupset plus selected groupset. The four published build references use Ultegra Di2. For example, the Canyon Aeroad CF SLX 8 Di2 starts at 7,600 g with its 1,637 g original wheels and the 2,750 g Ultegra reference-kit allowance. Choosing the 1,493 g ENVE SES 4.5 reference gives 7,456 g. Choosing the 2,350 g RED AXS kit estimate as well gives 7,056 g, displayed as approximately 7.06 kg.
For models without a verified complete-build reference, the total is frame plus wheels plus selected groupset plus the remaining estimated components: fork, cockpit, seatpost, saddle, tyres and fittings. TT estimates also allow for extensions and empty storage or hydration hardware. The selected groupset replaces the old generic drivetrain-and-brakes allowance. It is never added on top of another groupset.
For published complete builds, Other components is the reference total's remainder after subtracting frame, factory wheels and reference kit. It is not a separately measured component total. Size, paint, tyres, gearing, power meters, tape, sealant and accessories can change a real build's mass. The reference size and measurement conditions can also differ between models; weigh the assembled bike for a definite result.
6. Turn a visual choice into a compatible build
Matching an image is only the first step. Before ordering components, check the exact frame and wheel generation with the supplier. Work through wheel diameter, axle dimensions, brake mounting, freehub and cassette compatibility, internal rim width, approved tyre combinations and inflated tyre clearance.
A rim's depth alone does not answer those questions. Nor does it establish handling or aerodynamic performance: the photographed wheel, tyre shape, bicycle, rider and conditions all matter. For a rear disc, also check the manufacturer's operating guidance and your event's equipment rules.
Also check the groupset's brake system, bottom bracket, cassette/freehub, derailleur mounting and control routing. A rim-brake reference kit does not fit a disc-only frame simply because it can be selected here. The photographed drop-bar controls are reference parts; a TT cockpit may need different shifters, levers and wiring. Groupset selection compares mass and does not certify these interfaces.
Frequently asked questions
Why do some front and rear rims have different depths?
Several of the actual wheel pairs in this catalogue use different front and rear rim models. The selector reports the pair rather than pretending it is one depth. For example, ENVE SES 3.4 appears as 39 / 43 mm and SES 6.7 as 60 / 67 mm.
Can I choose any depth number?
The depth selector only offers the photographed catalogue combinations for the chosen series. It does not stretch a rim photograph to invent a new wheel model.
Does changing paint change the weight?
The tool does not measure paint mass. It can use a different original wheel reference when the catalogue photograph of a paint has a different factory pair, as on some Colnago Y1Rs finishes. That wheel-reference change can affect the estimate.
Are the wheels guaranteed to fit the selected frame?
No. The photographic layer is positioned at the wheel centres; mechanical compatibility is not simulated. Check the exact interfaces, tyre approval and clearances with the supplier.
Can I save a build or buy it here?
The current tool keeps selections only while the page is open. It has no account, saved-build database or checkout. Product links take you to outside reference sites, each with its own availability and terms.
