"What Our Gearhead® Experts Are Saying:""I run the Twinty 2X Chainguide (ISCG, 36–40t) on my enduro bike—it's bomber. The bashguard has taken serious hits and my drivetrain hasn’t skipped a beat. No noise, no fuss, just secure shifting even when things get rowdy.""For riders who hammer big terrain with big chainrings, the Blackspire Twinty 2X Chainguide with ISCG mount (36–40t) is a quiet guardian against dropped chains and bashed drivetrains. Whether you're racing enduro or just riding aggressively, this guide keeps your drivetrain focused and friction-free. Mounted via ISCG tabs and designed specifically for 36 to 40-tooth chainrings, the Twinty 2X features a proprietary polymer slider that guides the chain silently with minimal resistance. The integrated bashguard absorbs impacts that would otherwise compromise your rings—so you can charge rocky descents with confidence. Optimized for SRAM 2x10 cranks but adaptable to a range of setups, this guide is lightweight, efficient, and ready to roll as hard as you do."
