Very elegant and exclusive chainring for mounting on 4-arm cranks. It replaces the middle sheet in the conversion of a 3- to 2-fold crank. Compatible with Shimano XTR FC M970 and -980 cranks.
Titanium chainrings are the first choice for frequent travelers, as they have a longer life than aluminum sheets.
High switching precision by consuming incorporated climbing aids.
