The SLF Motion wheels are designed to reduce drag where the chain flows through the rear derailleur and drastically improve the durability of these moving parts. Benefits include enhanced riding efficiency through better power transference from rider to bike as well as improved durability compared to any other product on the market.
My overall ride experience has felt noticeably smoother, quieter and more efficient.
