Islabikes, renowned for crafting high-quality bicycles, has re-entered the market with the Rosetta, a gravel bike that defies traditional design norms. This innovative model features a step-through frame and a flat handlebar, setting it apart from conventional gravel bikes.
Design and Features
The Rosetta’s step-through frame is a deliberate choice by founder Isla Rowntree, inspired by her cycling adventures in the British countryside. This design facilitates easier dismounting when navigating obstacles like fences and gates, especially when equipped with panniers. The rearward weight distribution of panniers enhances rear-wheel traction and simplifies bike lifting over obstacles. (bikeradar.com)
Opting for a flat handlebar, Rowntree emphasizes a more natural hand position for off-road terrain, enhancing control and comfort. The frame is produced by Stayer, an East London-based bike builder, ensuring quality craftsmanship. High-quality bearings and brakes from Hope Technologies are incorporated, while an affordable Shimano CUES drivetrain offers low gearing suitable for real-world climbing. (bikeradar.com)
Additional Components
The Rosetta is equipped with mudguards, a rear rack for panniers, and a dynamo system that powers front and rear lights and can charge devices like smartphones. The rear light, mounted on the rack, can be detached by disconnecting the dynamo wire near the down tube, facilitating easier removal when traveling. The bike accommodates 45mm gravel tires, with clearance for up to 57mm, catering to various riding preferences. (bikeradar.com)
