[Custom colour option available] Lewis Titanium Crankset: Raw Strength, Zero Compromises Forget what you know about aluminum. The Lewis Ti crankset is in a class of its own — precision CNC’d from aerospace-grade titanium, built for riders who treat trails like battlegrounds. This isn’t just an upgrade — it’s a whole new tier of durability, stiffness, and long-term reliability. Material: CNC-Machined Titanium Alloy Weight: 659g (w/ 29x100mm DUB Boost spindle + fix ring) Spindle: 29mm DUB Boost Chainring Interface: SRAM 8-Bolt Crank Arm Length: 162.5mm Where aluminum cranks eventually fatigue, titanium shrugs off the hits. With its naturally high tensile strength and unmatched fatigue resistance, the Ti arm holds its shape season after season, ride after ride — no creaks, no flex, no dead feel. The hollow-arm design keeps weight in check, while delivering the kind of torsional stiffness you normally only see in high-end DH setups. Compared to forged 7075 aluminum, titanium offers greater impact resilience and long-term strength retention — perfect for gravity riders who need their components to take a beating and come back for more. Finished in raw titanium, corrosion-proof and unapologetically industrial, this crank is built to last longer than your frame — and look better doing it.   ------------------- Important Note:Custom option will take longer time to prepare, and cancellation , exchange ,return & refund not applicable for this product, please consider carefully before making decision, for further detail, please refer to our policy page or contact our customer service for assistance.
