Our verdict
Overall
out of 100, average of 7 categories
An affordable, direct-sales tri bike with modern standards: threaded T47 bottom bracket, five sizes, a hydration tank and plenty of build options. There is no published aero data, the default wheels are shallow alloy and the integrated bar limits cockpit swaps.
