Insight Mini Chain Tensioners

Overview

Insight Mini chain tensioners are lightweight forged aluminum components designed for BMX racing bikes with 6mm rear axles. These compact tensioners maintain consistent chain tension through a single-screw adjustment system with counter nut for secure locking.

Key Features
