E*THIRTEEN chainring Helix Race e*spec | round | Direct Mount Bosch SX / CX Gen4 | eggplant
The Helix e*spec Direct Mount chainring combines modern design and performance. It is first forged and then given the finishing touches using a milling process.
The "spokes" have been slightly shortened and made wider, thus significantly stiffening the entire chainring. The new and narrow M4 tooth profile improves chain retention and ensures compatibility with many 11-speed and 12-speed drivetrains, such as SRAM (including SRAM Eagle transmissions), Shimano and TRP.
Note: The crank shown is not included in the scope of delivery.
