1. Introducció
This manual provides detailed instructions for the installation, operation, and maintenance of your LEXON Road Full Carbon Crankset. Designed for road bicycles, this superlight crankset features a 24mm Titanium Spindle and is compatible with 11S/12S systems. Some models may include an XCADEY Power Meter for advanced performance tracking.
The LEXON Road Full Carbon Crankset is engineered using Toray high modulus carbon fiber, resulting in a lightweight design (as low as 362g for 167.5mm cranksets, spider not included) and superior rigidity. The second generation of dual-channel technology enhances crank rigidity by 12%. Its highly compatible 24mm axle adapts to various frames, and the titanium axle core ensures exceptional rigidity and durability. The crankset has passed rigorous 1800N 14w crank fatigue and 5600N crank damage tests, exceeding EU standards.
RYET Chainrings, often paired with this crankset, offer an optimal balance of weight, stiffness, and strength. Constructed from ultra-light aviation grade 7075 aluminum, their 5.6mm thick structure provides a firm and strong product. They are 12% lighter and more rigid than traditional aluminum sprocket blades, featuring an optimized tooth profile for fast and accurate gear shifting.
2. Critical Safety Warnings
- Torque Wrench is Mandatory: You MUST use a calibrated torque wrench for all bolts. Overtightening can damage carbon fiber or aluminum threads, leading to catastrophic failure.
- Verificar la compatibilitat:
- Road Models: Ensure your frame's bottom bracket standard (e.g., BB86, BB30, PF30) is fully compatible with the crankset's spindle diameter (24mm or 29mm) and the corresponding bottom bracket.
- Mountain Models: Ensure your frame's bottom bracket standard (e.g., BB92, PF30) is fully compatible with the 29mm spindle and its specific bottom bracket.
- Use Carbon Assembly Paste: Always apply a thin layer of carbon fiber assembly paste to all carbon-on-carbon contact surfaces (e.g., spindle interface, preload cap) to prevent slippage and creaking.
- Do Not Use Damaged Parts: Inspect the crank arms, chainrings, and all bolts for any cracks or damage before installation. Do not install if compromised.
For safety and optimal performance, professional installation by a qualified bicycle mechanic is strongly recommended.
3. Configuració i instal·lació
This section outlines the key steps for installing your LEXON Road Full Carbon Crankset. Refer to the diagram below for visual guidance on component identification.
3.1 Key Installation Steps
- Install Bottom Bracket: Press-fit or thread the correct bottom bracket cups into your frame according to its standard.
- Install Crankset:
- Insert the drive-side crank arm/spindle through the bottom bracket.
- Attach the non-drive-side arm and hand-tighten the fixing bolt(s).
- Set Preload (if applicable): For systems with a preload adjuster, turn until all play is eliminated and the crank spins smoothly.
- Parell final: Using a torque wrench, tighten all fixing bolts to the exact specification printed on the crank arm, following a cross pattern. Do not exceed the specified value.
- Install Chainrings: Secure the chainrings to the crank arm using the chainring bolts. Torque to spec (typically 10-14 N·m) in a cross pattern.
3.2 Component Details
The crankset features a 24mm Titanium Spindle, designed for optimal performance and durability.
The LEXON Standard Spider (50g, AL7075) is suitable for RYET cranksets and uses an EASTON Interface System. The kit includes chainring bolt kits and various spindle/pedal spacers for precise fitting.
3.3 Bottom Bracket Compatibility
Ensure your bottom bracket is compatible with the 24mm Chromoly Spindle. Refer to the compatibility chart below. Note that the bottom bracket is not included with the crankset.
Important: RYET Chainrings are not directly compatible with SHIMA** Cranksets. Please verify compatibility before installation.
4. Operation (XCADEY Power Meter)
If your crankset includes the XCADEY XPOWER-S Power Meter, follow these instructions for operation and data tracking.
4.1 XCADEY APP Connectivity
The XPOWER-S power meter can be connected to the new XCADEY APP. This application allows you to view real-time data such as watts and cadence, check hardware information, adjust settings, and upgrade firmware.
4.2 ANT+/Bluetooth 4.0 Dual-Mode
The XPOWER-S features an ANT+/Bluetooth 4.0 Dual-Mode chip, enabling seamless connection with various cycling computers and smart devices. It is compatible with Garmin, Bryton, Wahoo, and other ANT+ enabled bike computers. You can also connect it to smartphone apps like Strava, Zwift, Onelap, and TrainerRoad for comprehensive training analysis.
5. Care, Inspection & Maintenance
- Comprovació inicial: After the first 50 km of riding, re-check the torque on all crank and chainring bolts, as settling may occur.
- Inspecció periòdica: Periodically (e.g., monthly) check bolt torque and inspect crank arms and chainrings for cracks, unusual flex, or noise.
- Neteja: Esborra amb anunciamp cloth. Avoid directing high-pressure water at bearing seals or bolt interfaces. Do not use corrosive cleaners.
- Lubricació: Use only specified lubricant or anti-seize compound on metal threads. Never use grease on carbon contact surfaces.
6. Solució De Problemes
If you encounter any issues with your LEXON Road Full Carbon Crankset, consider the following:
- Unusual Noises or Play: Re-check all bolt torques as per the installation instructions. Ensure proper preload adjustment if applicable. Inspect for any signs of wear, cracks, or damage on crank arms, chainrings, and spindle.
- Shifting Issues (with RYET Chainrings): Verify that the chainrings are correctly installed and torqued. Ensure your drivetrain components (derailleurs, chain) are compatible and properly adjusted.
- Power Meter Inaccuracy or Connectivity Problems: Check the XPOWER-S battery level. Ensure your cycling computer or smartphone app is updated and correctly paired via ANT+ or Bluetooth. Refer to the XCADEY APP for diagnostics and firmware updates.
For complex issues or if you are unsure about any repair, it is highly recommended to consult a qualified bicycle mechanic.
