The new generation of the Mille GT from Assos serves as the basis for the wearable. The road cycling shorts are designed for long tours by combining a thick seat pad with an elasticated outer material. Compared to the previous model, the comfort shorts have fewer seams, which, in combination with the seamless X-braces, results in an excellent feel against the skin. The Swiss company has also opted for a slightly thicker seat pad, which our test rider found to be a good compromise between comfort and stability. We would tend to recommend the Mille GT for amateur athletes and leisure cyclists whose sit bones are somewhat less robust than those of frequent riders.
Assos Mille GT Whoop C2: The most important facts
- Equipment: comfortable padding, seamless X straps, compatible with Whoop 4.0
- Weight: 195 grams (weighed weight, size M)
- Sizes: XS, S, M, L, XL, 2XL, 3XL
- Price: 165 Euro
- Country of manufacture: Bulgaria
The Whoop tracker is inserted into a small pocket that is placed over the left side of the buttocks. According to Assos, a total of five positions for the sensor were tested during the development phase. In the saddle, you don't notice the small, 27 gram tracker. The optical sensor lies directly on the skin so that it can record biometric data such as heart rate, breathing rate or skin temperature. But it doesn't necessarily have to: in the practical test, data recording even worked with a thin vest. Whoop automatically recognises the type of sport via the heart rate profile. However, you can also select this manually from a list of over 60 activities.
Unlike smartwatches, Whoop is a pure fitness tracker without a display. The focus is on stress management, whereby a distinction is made between the parameters of stress, recovery and sleep. The basis for this is the heart rate; algorithms are also used to determine the blood oxygen content, among other things. The device can also be "fed" with up to 140 habits via a so-called logbook. A daily query in the German-language app allows you to select, for example, whether you read in bed before going to sleep, whether you have consumed alcohol or when you ate your last meal.
Whoop 4.0: The most important facts
- Functions: Fitness tracker, virtual AI coach
- Measured values: e.g. resting heart rate, heart rate variability
- Waterproof: up to a depth of 10 metres
- Artificial intelligence: GPT-4 from OpenAI
- Data analysis: via smartphone app
- Weight: 27 grams (weighed weight)
- Subscription prices: 264 euros (1 year), 444 euros (2 years)
The more information that is shared, the better the recommendations for rest and sleep phases and the forecasts for exercise capacity work. Although our tester severely limited the query, the effort involved is still relatively high. For professionals, tracking may be part of everyday life, but amateur athletes may quickly feel like a "transparent athlete". The new generation also offers a coaching function using artificial intelligence. The so-called Whoop Coach can, for example, provide customised training plans.
The Assos Mille GT Whoop C2 is available for 165 euros. Compared to the "normal" version without the Whoop bag, it is 20 euros more expensive. The Swiss also offer a women's model (Uma GT Whoop C2). The fitness tracker is only available as a subscription model. A one-year membership costs 264 euros, while a two-year membership costs 444 euros. A 30-day membership is free of charge. Anyone already using Whoop should note that the cycling shorts are only compatible with the current 4.0 generation of the tracker.
