Loading store availability...
Helix Race GR chainrings are gravity optimized direct mount chainrings designed to withstand the punishment of downhill, bikepark, and freeride disciplines. They’re crafted of AL-7075-T6, and highly CNC optimized for minimal weight penalty, and great looks. Paired with Helix Race GR Cranks, -7mm offset GR chainrings produce a 56.5mm chainline suitable for most long-travel bike geometries. Featuring e*thirteen’s M4 narrow-wide tooth profile, they deliver improved chain retention, reduced noise and system wear, and seamless compatibility with both Shimano and SRAM drivetrains, (including T-type).

Tool was exactly how described and packaging was nice. It did take a few days to ship so unfortunately I didn’t receive it in time for the trip I ordered it for which is the reason for 3 stars but I received it the week after and it’s coming in handy.
size is big enough and clear simple layout. moved from garmin 850. I am very satisfied with wahoo!
Sierra is no joke, this is our 4th bike in the last 3 months and the process has been so easy, they are fair with pricing and never make it feel transactional! I won't be buying anywhere else!
