Cosmic 700C RX-25 - Text Review

At its core, the Cosmic RX-25 features a lightweight 6061 alloy frame engineered for endurance and efficiency. The geometry strikes a balance between road-bike aerodynamics and upright comfort — ideal for longer commutes and fitness rides. The frame’s clean internal cable routing and matte paint finish give it a premium look in its price range.

The RX-25 is powered by a 2×7-speed Shimano drivetrain, offering a total of 14 gears for tackling flat roads and mild climbs. The Shimano Tourney derailleurs paired with EF500 trigger shifters provide smooth, reliable shifting performance suited for fitness and daily use.

Gear ratios are optimized for moderate city gradients you get quick acceleration on flats and enough range for rolling terrain. Pedaling feels smooth and efficient, especially at mid-to-high cadence.

The RX-25’s riding comfort is one of its strong points. The upright handlebar position reduces wrist strain and supports better visibility in traffic. The alloy frame absorbs light vibrations effectively, while the rigid fork keeps steering precise.

The 700×35C tires strike the right balance between speed and grip, ensuring stability on urban roads and paved trails. The ergonomic saddle supports medium-length rides comfortably, and the adjustable seatpost allows quick fit customization.

Equipped with mechanical disc brakes, the RX-25 offers confident and consistent stopping power in both dry and wet conditions. Brake modulation is predictable, giving riders more control during sudden stops or downhill descents.

The flat handlebar and lightweight stem offer a responsive steering feel, keeping handling agile yet stable even at higher speeds.

The double-wall alloy rims with quick-release hubs make the wheelset both strong and easy to maintain. The 700×35C hybrid tires roll fast on smooth surfaces while offering enough traction for rough patches.

The Cosmic comfort saddle is designed for a neutral seating position firm enough for efficient pedaling yet padded for urban bumps.
