A good fit for road, gravel, commuting and general-purpose riders who want a light, colourful cage with easy bottle access and dependable everyday retention.
The ZEFAL Pulse B2 gives you a straightforward, lightweight way to carry water on your bike. At 30 g, it adds very little to your build, while the bi-component polyamide construction balances rigidity and flexibility rather than making the cage unnecessarily stiff.
Its reinforced composite centre helps reduce vibration and hold the bottle securely, while the flexible technopolymer exterior makes insertion and removal easier. Independent testing found that bottles stayed in place over rough roads, gravel trails and potholes, with different bottle diameters held securely; another test found the cage particularly easy to access and confirmed that it remained secure over a rough route.
For a clean, coordinated build, the Pulse B2 is available in 10 colours; this version is white with black detailing. It fits all standard bottles, includes the mounting screws and is made in France. The lower mounting hole provides a small amount of fitment adjustment, while installation is simple with a 4 mm hex key—grease the threads first and tighten moderately.
