Description
Product Overview
The BUCKLOS MTB Crankset is engineered for riders who demand a blend of strength, lightness, and simplicity. Crafted from high‑grade aluminium alloy, the crankset weighs only 609 g while delivering the rigidity needed for rugged off‑road terrain. It features a 104 BCD design compatible with 32‑42T chainrings, available in both round and oval profiles, and in black or red finishes. Each chainring is a narrow‑wide 4 mm thick unit with precisely machined teeth (1.9 mm narrow, 3.7 mm wide) to reduce chain drop and improve power transfer. The package includes the crank arms, a single‑speed chainring, and four stainless‑steel bolts for a complete, ready‑to‑install solution.
Usage

Whether you’re tackling steep forest trails, navigating city streets, or cruising on an e‑bike, the BUCKLOS crankset provides consistent performance. Its square‑taper interface ensures a secure fit on standard bottom brackets, making it ideal for riders who prefer a straightforward drivetrain without the complexity of multiple gears.
