Thanks. Ya, I wondered that too - - but that's what comes with the base Enduro build kit (Race and Pro build kits come with 2X XT/XTR respectively). Eventually, I plan on ditching big ring, putting on a Sunline poly bash and doing a, say, 38/26 or similar combo and something like a Blackspire Stinger guide. Or maybe just bite off the big one and go Hammerschmidt . I imagine yours is long gone, huh? Sorry I never followed up.
