Built with care: Our mechanics fully assemble your bike before it's carefully packaged and shipped to you.

At Tweeks Cycles, we ensure your bike arrives fully assembled and, most importantly, well packaged so it arrives with you as it left us.

Upon delivery, simply unpack it, attach any included pedals (believe it or not, some bikes don’t come with pedals!), adjust the handlebars, and you're ready to ride!

It’s all super simple!

BUT! Please take extra care when fitting any pedals that are provided with your bike. Pedals are side specific and MUST be fitted to the correct side of the bike. They are usually clearly labelled Left and Right. Failure to do so will permanently damage the bike, void the bikes warranty and lead to many tantrums, for children or grown children alike!

Comprehensive 14-Point Inspection

Each bike undergoes a meticulous 14-point inspection to guarantee optimal condition and performance:

  • Ensure Cycle is free of any mechanical damage, paint chips or missing parts
  • Grease seat tube, secure seat clamp, make sure the saddle is level and ensure all fixings are secure
  • Ensure handlebar, stem and brake/gear levers are secured
  • Assess headset for play or tightness
  • Ensure handlebar tape or grips are fitted securely
  • Ensure wheel nuts, quick-release levers or through axles are tightened (please note: some adult mountain bikes come with the front wheel removed for transport), true the wheels for optimal alignment and check wheel bearings for proper adjustment
  • Inflate tyres to the correct pressure
  • Ensure front and rear brakes operate correctly. Bleed hydraulic brakes if required
  • Ensure pedal threads are greased
  • Test all gears to ensure smooth operation
  • Check suspension system for correct operation and ensure bolts are tight (if required)
  • Ensure smooth bottom bracket rotation with no free play and secure crank bolts
  • Check cable/house routing and that cable ends are fitted
  • Install reflectors and bell

This thorough process ensures your bike is in peak condition upon arrival. We do not fit mudguards or other accessories prior to shipping as these are likely to be damaged in transit.

Note on Electric Bikes

Due to shipping restrictions, in some circumstances you may receive your new electric bike and its battery separately. This is due to carriage restrictions on some removable batteries.

Note on Balance Bikes

Balance bikes are shipped unassembled, allowing you to enjoy the building experience and retain the original packaging-perfect for gifting.

Details

Speed-focused and race-ready, the Cannondale SuperX Carbon 3 Gravel Bike is built to win. With a sub-1,000g frame, advanced carbon construction, and race-proven components, it delivers a fast, responsive ride with the strength and control needed for aggressive gravel racing. From lower drag to increased tyre clearance, every detail is engineered for pure performance and long-haul speed.

Key Features and Benefits:

  • Sub-1,000g carbon frame (size 56): This ultra-lightweight frame reduces the overall bike weight. A lighter bike allows for faster acceleration and improved efficiency. The result is quicker climbs and reduced fatigue over long distances.
  • Refined carbon layup for stiffness and compliance: The frame balances power transfer with shock absorption. Stiffness helps you maintain speed under load, while compliance softens rough surfaces. This leads to better control and less fatigue during demanding rides.
  • Shimano GRX 820 gravel-specific groupset: Built for mixed terrain, it offers crisp shifting and confident braking. You get reliable performance in all conditions. This ensures precise gear changes and control when it matters most.
  • Reserve 40/44 GR carbon wheels with DT Swiss 370 hubs: These wheels provide aerodynamic advantage and long-term durability. Paired with wide tyre clearance (up to 48mm rear, 51mm front), they support stable, low-pressure grip. This means better traction, speed, and comfort on rough gravel.
  • Integrated cockpit with Cannondale C2 alloy bar and C1 Conceal stem: The setup combines strength and weight savings with a clean front-end profile. Better integration reduces drag and increases handling precision. It helps maintain speed and control in tight racing situations.
  • Race-driven geometry and tyre clearance: Geometry is tuned for fast handling with stability. Wider tyre fitment allows for more grip and comfort. This helps you stay fast and focused across loose, uneven terrain.

Built for racers who demand speed over distance, the SuperX Carbon 3 is engineered to perform under pressure. Its aero-tuned design, low weight, and drivetrain efficiency align with the demands of competitive gravel riding. With support for wide tyres and precision handling, it offers the control needed to hold speed on tough courses. Every component is selected to meet the needs of high-speed gravel racing, with minimal compromise.

Ready for race day or fast gravel miles, this bike brings proven performance to the front of the pack. If you're aiming for personal bests or podium finishes, the SuperX Carbon 3 is built to help you get there with speed and confidence.

A bike has to go though a Pre Delivery Inspection (PDI Check) prior to despatch, ensuring the bike is thoroughly checked and set up prior to you receiving. This also means an express delivery service is unavailable. We strive to despatch bikes within 3-5 working days. Please note this may change over school holidays and the festive season (November/December). For more information on the process please visit our pre-build page.
