Built for time trial and triathlon testing. Proven CdA Analysis • Speed Lab is now focused squarely on aerodynamic testing — one hardened, field-proven path from your ride data to a CdA number you can act on. • Rolling resistance can be set directly, so you can pin it to your own setup. Group Your Analyses However You Test • Organise CdA tests by bike, by venue, by circuit, by session — or anything you like. The labels are yours to invent. • Collapsed groups show how many runs they hold and your best improvement, so a season's testing stays readable at a glance. • The bike picker understands your groups, so choosing the right bike is quick. Bicycle Groups • Organise bikes into your own named groups: team bikes, bike mods, athlete mods, fitter groups — or anything you like. • Create, rename and remove groups, and move bikes between them. • Import straight into a group, and export a whole group in a single file. More Measurements • 19 optional advanced fields covering frame geometry, cockpit, saddle specs, cranks and pedals, and aero/tri bars — matching the Android app. • New saddle tilt measurement. • All of it carries through export and import, so nothing is lost when you share a bike between phones or with a fitter. Cosmetics and Usability • Fixed buttons that could stop responding on some iPhones. • Rebuilt bike cards, with Duplicate and Delete right there on the card. • New in-app guide explaining grouping, plus visual polish throughout.

**NEW** Cda and Crr analysis from .FIT files (with power and GPS readings). (A Beta feature - must have internet connection) - New Aerodynamic Drag x Frontal Area (CdA) and Rolling Resistance (Crr) coefficients. - Calculate between two FIT files a base and a comparison and choose conditions. - Includes Air Density and Speed calculation - can use different types of Tires, Riding positions, and many other configs. - Export Analyses easily to support best setups for events. Improvements - Easy cross platform export of Bike Fits - Share to see on browsers or send to someone in a different platform (iOS and Android) - Use exports to import as well - Beautiful interactive display of your fits with bicycle Photos and sharing as a browser file (Desktop and non-iOS browsers) - Multi Export/Import of bicycles for sharing or backup.
