Helix Race e*spec Chainrings merge cutting-edge design and performance. Designed for Bosch SX and Gen 4 CX equipped e-bikes, this 1pc direct mount chainring is forged from 7075 AL for lightweight durability, impressive stiffness, and a standout technical aesthetic. Its custom metal dust cover enhances style and minimizes seal and lockring contamination. The new M4 narrow-wide profile delivers enhanced chain retention and cross-compatibility with Shimano, Sram, and TRP 11/12s drivetrains, including SRAM T-Type.

Shipping for some reason took weeks to arrive. Item arrived after I needed it so it was no use to me.
Great unit, works as expected. Sierra was quick to deliver and easy to work with. Thanks!
Excellent helmet, nice colour and great performance. It is very fit ti the head.
Thank you !!!
Great softer materials but not the same support as the previous season. Pockets are large enough to fit stuff but the straps don’t support well. No chance you’re getting a water bottle in there. Also the bin straps position themselves right on top of your nipples. You’re going to notice that after an hour of pedaling and sweating.
I really liked the previous version so
Much that I wore 2 pairs out with 6000 miles. These new ones will be lucky to make it into rotation.
