The XO triple crankset is a good choice for the rider who wants unlimited gear choice in a SRAM drivetrain. It offers all of the niceties of the 2x10 XO crankset with an extra chainring to widen the gear options. Beautifully ramped and pinned X-Glide chainrings are CNC machined to perfection and mounted to the carbon crank arms via an aluminum spider. The spider itself is anodized to match the chainrings. The rings feature machined reliefs between the spider arms for additional weight loss. The carbon arms are super durable and gloss coated for additional protection and good looks.
SRAM pays a lot of attention to gearing and it shows with the unique 33t middle ring. The added 1 tooth, up from a standard 32t ring, makes the gear ratios close to perfection for a triple crankset. The familiar red/black XO graphics give the crankset a quality look and appeal. This XO crank requires a standard GXP bottom bracket which is not included.
