Lambro 27.5 - Text Review

The core of the LAMBRO 27.5 is a Hi-Tensile Steel Frame. While heavier than an alloy frame, steel provides excellent durability and a comfortable, shock-absorbing ride quality that is beneficial on rough roads. The geometry is generally designed for a comfortable, upright riding posture, making it easy on the back for commuting or long fitness rides.

The design carries the retro-modern aesthetic hinted at by the Lambretta brand, featuring bold looks. The use of a 27.5" wheel size hits a sweet spot, offering better roll-over capability than smaller wheels but maintaining greater agility and a lower stand over height compared to 29ers. The frame size is typically around 17 inches, catering to a specific range of riders, but fit should be confirmed with the retailer.

This 21-speed system offers a generous gear range, suitable for tackling steep climbs (thanks to the small chainring) and maintaining speed on flats. While Tourney is an entry-level component, it is generally reliable when well-tuned, offering smooth and crisp shifting for non-competitive, everyday use. The performance is adequate for urban environments, fitness rides, and light off-road paths, which is the intended use case.

Shifters/Derailleurs: Shimano EF-500 shifters control Shimano Tourney TY-500 (front) and TY-300/500 (rear) derailleurs.

Crankset: The front is a triple chainring setup, providing a very wide range of gears.

Cassette: A 7-speed freewheel.

Comfort is a key feature, driven by several factors:

• Frame Material: The steel frame inherently offers better compliance than stiff aluminum, absorbing road vibrations.
• Fork: The front suspension fork further enhances comfort by smoothing out bumps and rough patches.
• Tires: The wide 27.5" x 2.40" tires provide a large air volume, which significantly cushions the ride, offering superior stability and grip on uneven surfaces.

The combination of geometry, suspension, and high-volume tires results in a comfortable ride, well-suited for city roads, potholes, and introductory trails. The saddle is typically an ergonomic, PU comfort foam type, designed for general use.

Disc brakes are a significant advantage over rim brakes, providing effective braking with adequate stopping power, especially in wet or dusty conditions where rim brakes can suffer. They require less hand force for powerful stops and are more consistent.

Steering is generally predictable and stable, thanks in part to the 27.5" wheels and the MTB-oriented handlebar setup (around 640mm wide). While the front suspension adds comfort, it is a basic unit, which is acceptable for the price point and intended use of leisure and light trails.

The wheels feature 27.5-inch Double Wall Alloy Rims attached to steel hubs. Double-wall rims add durability and strength, making them more resistant to damage from impacts (like hitting potholes). The hubs are designed for disc brake compatibility.

The 27.5" x 2.40" Nylon tires are a standout feature, providing an aggressive look and excellent all-terrain capability. Their generous width provides:

1. Increased Stability and Grip: Excellent traction on loose surfaces, gravel, and wet city roads.
2. Increased Comfort: The air volume acts as a natural cushion.

The size choice (27.5") maintains the bike's agility, making it easy to handle in city traffic while being capable enough for light trail excursions.
