Our Cratus chainrings bolts were born from the frustration of low-grade alloy bolts rounding during installation and loosening over time, causing zero-offset drifts on powermeters.
We've specified S316 stainless steel and a Torx T30 head for better engagement and long term durability. Laser-etched logos on a black finish give the high quality aesthetics you expect from WattShop.
The reverse side, female bolt is a Torx T25 head with a knurled surface to eliminate slippage.
Available in sets of 4 or 5 to suit your requirements.
Please note these are specific 2x chainring bolts.
