Product Description

Turbocharger Race e*spec | 104BCD Spider plus 34T Bashguard | 34T Ring | Bosch SX | 55mm CL | 15.5mm Offset 
| Incl. Chainring, Bolts and Nuts | Black/Sterling Silver

The Turbocharger Race espec Spider, Bashguard, and 34T Chainring kit* is engineered to give Bosch SX riders the highest level of drivetrain protection and chain security available for compact e‑MTB systems. Modern lightweight motors like Bosch SX leave the chainring exposed to impacts—especially on heavier e‑bikes that lack ISCG tabs. This integrated Turbocharger system solves that problem 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 Bosch SX version uses a 15.5mm offset to achieve a perfect 55mm chainline, ensuring smooth power transfer and 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 Bosch SX frames and is also compatible with Bosch CX Gen4.

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