Just in time for your ’14/’15 season prep comes the new Race Face Narrow/Wide Cyclocross Chainrings.
They use the same thick/thin alternating tooth profiles as their mountain bike single chainring, which we’ve started reviewing here. They’ll be offered in 110BCD (38/40/42) and 130BCD (40/42/44), in black only for starters. They can be mounted to the inside or outside of your normal double chainring crankset’s spider, yielding a 46.5mm chainline when mounted on the outer face (recommended) and 40mm on the inside. Standard road double chainline is roughly 45mm.
Some sizes available now, others coming very soon. Retail is $59.99 to $69.99 depending on size. More below…
The chainrings can be run with either side facing out, stealthy or brand loyal. Other colors may come in the future if demand is there. They do not come with bolts, but should work with standard bolts/nuts on some cranksets. Depending on the design, and which side of the chainring you face outward, you may need short or single speed bolts/nuts.
Rob at Race Face weighed a 110/42t and 130/44t chainring, and both ended up at 76g.
