Surly O.D Chainring Guard

Features: Single chainring drive train setups are all the rage these days. With the introduction of exceedingly wide range 10- and 11-speed cassettes, the need for two chainrings has become a thing of the past.  But when you only have one chainring, the only thing standing between you and a long walk back to the trailhead is you making sure you don't destroy your one chainring.  That's why Surly made a charing guard to fit our O.D. cranks.  It is made of aluminium and will take the hit for your chainring.  It comes in 5 bolt, 94mm BCD.

Surly Cassette Cogs

Shimano compatible Spline fitting.9 Speed spaced, these cogs can be run 9speed or less, together with Shimano 9Spd gear shifter systems. Note: Teeth profiles are straight forward, making them ideal for Single Speed applications, however, with no twists or ramps etc, the gear shifting will not be as slick as with regular Shimano cogs when used in a multiple cog line-up.The large foot print caused by built-in spacing at the base of these machined cogs gives a larger foothold on the cassette body, making these a premium selection for Single Speed or multi-speed use with reduced risk of torque transfer damage to the cassette hub body. (Note: This point is especially important with Alloy or Ti Cassette bodies.)
