Race Face Chainring with alternating tooth profile (XX1)
SRAM’s XX1 introduced a new chainring technology: Each tooth on the chainring has been precisely machined to integrate with both the inner and outer links of the chain perfectly.
Now Race Face offers this technology in his beautiful chainrings being compatible for 9-,10- or 11-speed chains making maximum chain control on the chainring a lot more affordable without the need to replace the whole transmission.
