The Turbocharger Race espec Spider, Bashguard, and 34T Chainring kit* is engineered to give TQ HPR50 riders the highest level of drivetrain protection and chain security available for modern lightweight e‑MTB systems. Motors like the HPR50 leave the chainring exposed to impacts—especially on heavier e‑bikes that lack ISCG tabs. This integrated Turbocharger system solves that vulnerability with a rugged, lightweight, and fully compatible solution.

The kit combines a 104BCD forged‑and‑CNC’d AL7075 chainring, a reinforced composite Bashguard, and a precision‑machined 104BCD Spider. The TQ HPR50 version uses a 12mm offset to achieve a perfect 55mm chainline, ensuring smooth power transfer, clean shifting, and optimal drivetrain alignment.

The chainring features e*thirteen’s M4 narrow‑wide tooth profile, delivering exceptional chain retention and long wear life while remaining fully compatible with Shimano®, TRP®, and SRAM® 11/12‑speed drivetrains—including SRAM T‑Type. The compact, integrated aesthetic pairs cleanly with TQ HPR50 frames and maintains a sleek, modern look.

This kit includes everything needed for installation, plus spacers for running the Spider + Chainring without the Bashguard if desired.
