Here is a breakdown of what each specification means:

• Frame: The SMILE-Disc frame is made of AL7005 aluminum alloy. It features a thru-axle design with a diameter of 12x142mm, providing enhanced stiffness and stability. The frame has a flat weld and smooth construction, giving it a sleek appearance. The internal cable routing keeps the cables hidden and protected. The frame is finished with a glossy paint coat and adorned with UV laser decals.
• Handlebar Sets: The TW brand handlebar sets are made of aluminum alloy, which offers a balance of strength and lightweight. The handlebar has a matte finish and a diameter of 31.8mm, providing a sturdy grip. It measures 420mm in width, offering a comfortable and ergonomic riding position. The stem length is 80mm, providing stability and control. The seat post has a diameter of 31.6mm, ensuring compatibility with various saddle options.
• Clamps: The clamps are quick-release and made of aluminum alloy with a diameter of 34.9mm. These clamps allow for easy adjustment and secure attachment of components like the seat post.
• Fork: The SMILE-Disc fork is designed for 700C wheels and is constructed using high-modulus carbon fiber. This material provides excellent strength and stiffness while keeping the overall weight of the fork low. The fork also features UV laser decals for added aesthetics.
• Head Sets: The TW brand headsets are made of aluminum alloy and utilize sealed bearings. These headsets ensure smooth steering and reduce friction. The dimensions of the headsets are 42*52mm, which is compatible with the corresponding frame and fork.
• Washer: The washer is made of carbon fiber and measures 3x28.6x10mm. It acts as a spacer, providing a proper fit and alignment between components such as the stem and the fork.
• Derailleur Handle: The derailleur handle is from the SHIMANO TIAGRA 4700-20S series. This refers to the Shimano Tiagra groupset, which offers reliable and precise shifting performance with 20-speed gear options. It allows for smooth and efficient gear changes while riding.
• Front and Rear Derailleur: Both the front and rear derailleurs are from the SHIMANO TIAGRA 4700 series. The Tiagra series is known for its durability and reliable shifting. These derailleurs ensure accurate and crisp shifting between gears.
• Cranksets: The RS brand cranksets are made of aluminum alloy and feature a hollow design. This hollow construction helps reduce weight while maintaining strength and stiffness. The cranksets have a gear ratio of 34-50T, indicating the number of teeth on the chainrings, offering a range of gear options suitable for various terrains and riding preferences.
• Cassettes: The SUNSHINE-10S cassette is designed for 10-speed drivetrains. It offers a gear range of 11-28T, meaning the smallest rear cog has 11 teeth, and the largest has 28 teeth. This range allows for versatility in different riding conditions.
• Chain: The chain is from the SUMC-10S series. It is designed specifically for 10-speed drivetrains and ensures smooth power transfer between the chainrings and cassette.
• BB (Bottom Bracket): The BB is a threaded type with dimensions of BB68*24mm. It is hollow and features sealed bearings, providing smooth rotation and efficient power transfer between the crankset and the frame.
• Brake: The brakes are from the ZOOM brand and utilize a flat-mount hydraulic disc brake system. They operate with cable pull, providing reliable and consistent braking performance. The disc rotors have a diameter of 160mm.
