Im selling the Specialized S works Standard Chainring Set Used under 1000miles, I had to change chainring since my Quarq does not work with this chainring.
53 x 39
good condition
130BCD
Works for Shimano, SRAM drive
157 grams with bolt

This chainring came with my Tarmac SL3, so this is the newly designed ring set.

Also I have a size XS 2010 LA Langster for sale at $500 under 100miles and I\'m looking to switch from DA 7900 to SRAM Red Shifting sets.

Thanks
