An excellent choice for road, gravel, commuting and general-purpose riders who want reliable bottle retention, broad bottle compatibility and easy access without unnecessary weight.
The Pulse B2 uses bi-material construction to balance security and usability. Its reinforced composite centre helps reduce vibration, while the flexible technopolymer exterior adapts to different bottle diameters and makes bottle access easier. It is compatible with all standard bottles, so it is a straightforward choice for most everyday hydration setups.
In testing on rough gravel trails, the cage held bottles securely without them ejecting, while bottles from different brands remained firmly in place. The flexible outer sections provide a defined spring-like grip: firm enough for reliable retention, but easy to release when you need a drink.
At just 30 g, the Pulse B2 keeps weight low without resorting to a more expensive carbon cage. Screws are included, and installation is simple with a 4 mm hex key; use a small amount of grease on the threads and tighten moderately. Made in France and available in 10 colours, the grey version offers understated coordination with your bike.
