All-Mountain (AM) gearing options with a 49mm chainline for modifying existing X0 and X9 level GXP 10-speed cranks (BB30 spider/ring sets discontinued due to specific arm design needed for 49mm chainline. Use complete crank for BB30 AM rings)
asked by: a guest Can I use this on SRAM Force crank arms?
A.
anwered by: canteau The X9 spider will fit the Force crank arm, however, because the Force cranks use a narrower spindle the chainline might be a bit weird.
