This RED XPLR E1 crankset uses hollow carbon arms in 167.5mm length and includes a 42T aluminum X-SYNC ring. The natural-carbon version has a DUB Wide spindle and 47.5mm chainline.
The listed 12/13-speed compatibility is tied to SRAM Flattop road chains, not every chain with those speed counts. Check the full drivetrain and frame requirements, then choose the appropriate bottom bracket separately. Alternative ring sizes are not additional rings included with this 42T SKU.
