Explore Top-Quality Road Bike Components
Whether you’re aiming for a smoother ride, better performance, or a complete overhaul of your beloved road bike, the components you choose are crucial. Every rider knows that the devil is in the details—whether it’s the groupset that keeps your gears ticking over smoothly or the handlebars that offer the grip and comfort you need during long climbs. At Cranxs, we bring together a wide selection of new and second-hand road bike components from cyclists just like you, giving you the flexibility to find exactly what you need without breaking the bank.
Groupsets: The Heart of Your Drivetrain
A well-matched groupset can transform your cycling experience. From Shimano's reliable 105 to the high-performance Ultegra Di2, finding the right groupset for your riding style and needs is key. Whether you're after a smooth 12-speed upgrade or just need a reliable Shimano Sora for your weekend rides, our selection has you covered.
Handlebars: Control and Comfort
Handlebars do more than just steer—they shape your entire riding experience. From aerodynamic carbon bars for your racing bike to ergonomic options that ease the strain on endurance rides, the right set of handlebars can make all the difference. Explore options that fit your riding style, whether you prefer a classic drop bar or a modern aero design.
Pedals: Secure and Efficient
Pedals are where the power meets the pavement. Whether you're clipping into SPD-SL pedals for maximum efficiency or need a dual-sided pedal for a mix of road and casual riding, Cranxs offers a range of new and second-hand options that will keep you connected and in control.
Brakes: Precision Stopping Power
Braking performance is not something to compromise on. From disc brake sets that offer superior stopping power in all conditions to classic rim brakes for the traditionalist, we provide a wide selection of brake components, including levers, rotors, and pads. Upgrade your braking system to ensure your bike responds when it matters most.
Saddles: Ride in Comfort
Your saddle is your main point of contact with the bike, and comfort is key, whether you’re on a century ride or a quick morning loop. Choose from ergonomic designs that reduce pressure on long rides or lightweight racing saddles that keep the weight down and performance up.
Bottom Brackets and Cranksets: Power Transfer Essentials
Efficient power transfer starts at the bottom bracket and crankset. Whether you're upgrading to a stiffer setup for racing or replacing a worn-out part, finding the right combination can greatly impact your ride's responsiveness and smoothness.
Chainrings and Cassettes: Perfect Your Gearing
Dial in your gearing for any terrain with our range of chainrings and cassettes. Whether you're tackling steep climbs, needing more top-end speed, or just looking for a more durable setup, these components are essential for customising your ride.
Forks and Headsets: Steering and Stability
Your fork and headset are crucial to the bike's handling and stability. Explore carbon forks for a lighter, more responsive front end or rugged options for cyclocross and gravel adventures. Ensure smooth steering and durability with a quality headset, giving you confidence on every ride.
Seatposts and Clamps: Adjustability and Comfort
The right seatpost can offer more than just a place to sit. Adjustable seatposts allow for quick changes to your saddle height, while carbon models can absorb road vibrations, adding comfort on rougher roads. Ensure your setup is secure with a reliable seat clamp that holds everything in place.
Shifters and Handlebar Tape: Fine-Tune Your Ride
Shifters are your direct interface with the drivetrain, making them essential for smooth, responsive gear changes. Pair them with handlebar tape that offers the right mix of comfort, grip, and style. From ergonomic grips to colourful wraps, these small touches can make a big difference in your ride.
