Need just a little bit lower gear for those big climbs? The Wolf Tooth GCX 44t sprocket replaces the stock 42T on your XX1 or X01 cassette while adding some color if you prefer!  This is roughly equivalent to changing your current chainring to a 2t smaller chainring.  Shifting performance and durability matches the stock 42t cog but you will have a 5% lower gear.
