Description

The Shimano SH-RC503 sits in the RC5 line and is aimed at road cyclists who train regularly and want genuine power transfer without paying for a top-tier race shoe. The carbon-reinforced nylon midsole, rated 8 out of 12 on Shimano's stiffness scale, keeps energy loss to a minimum by ensuring your leg power reaches the pedals rather than being absorbed by a flex in the sole.

Closure is handled by a single BOA® L6C dial using Shimano's own lacing profile, which spreads tension evenly across the top of the foot. The result is a snug, adjustable fit without localised pressure — useful during back-to-back training rides where comfort matters as much as performance. The seamless perforated synthetic leather upper adds to this by reducing the risk of hot spots and irritation.

The shoe's low stack height — part of Shimano's DYNALAST last technology — positions your foot closer to the pedal axle, improving lateral stability and pedalling efficiency. Cleat compatibility covers the 3-bolt standard, meaning it works with both Shimano SPD-SL and LOOK KEO systems. The construction also incorporates 23% recycled materials by weight in the toe area and midsole.

Abus
BORDO™ 6200K/90 SH black ART 2
The ABUS BORDO™ 6200K/90 SH is a folding lock designed for cyclists who need genuine, insurer-recognised security. With an ABUS security rating of 13 out of 15, ART 2-star certification, and Sold Secure Gold Pedal Cycle approval, it meets the requirements of most bicycle insurance policies — a key consideration for anyone with a higher-value bike.
The lock bars are made from hardened steel, offering strong resistance to cutting and leverage attacks. Steel discs protect the rivets — typically a vulnerable point on folding locks — against saw attacks. The XPlus cylinder provides enhanced pick and copy resistance, and two keys are included in the box.
A 94 cm locking circumference and a 360°-rotating lock body give you the flexibility to secure your bike to posts, railings, bike racks, and other fixed structures with ease. The included SH frame bracket keeps the lock neatly on your bike and features a discreet compartment for a spare key.
Made in Germany, the BORDO 6200K weighs 1,320 g with a width of 67.5 mm — compact enough to carry daily, yet robust enough to stand up to determined theft attempts.

Endura
cuissard FS 260 II à bretelle noir
The Endura FS260 Bib Shorts II are built for riders who want a technical garment that stays comfortable from the first pedal stroke to the last. The pre-curved multi-panel construction mimics your riding position from the start, reducing bunching and friction over long distances.
The centrepiece is the Endura 600 Series chamois, featuring integrated gel inserts and a CVP (Continuously Variable Profile) cut calculated by computer. In practice, this means the padding is thicker exactly where pressure builds up and thinner where it doesn't need to be — a more precise approach than a one-thickness pad. An antibacterial finish rounds things off for added hygiene on extended rides.
The main fabric is Italian power Lycra® — a blend of polyamide and elastane — that provides firm support without restricting movement. The 100% polyester mesh bib straps wick moisture and dry quickly, which makes a real difference in warmer conditions. Ultralight silicone grippers at the leg openings keep the shorts in position without leaving marks.
Reflective detailing on the rear leg hems ensures you remain visible during early-morning or evening rides, without compromising the clean, minimal aesthetic of the short.
