I purchased this chainring for my Ultegra triple to go from a 52 to a 53 tooth for faster downhills. My mistake was that this is for a double, not a triple, so here it is for $10. New, they run anywhere from $60-80 and this is a new chainring, but without packaging.

It is for a 10 speed cassette, and from what I'm told, shifts best when matched with an inner ring labeled as this one "SG B." The 53 in the photo refers to the number of teeth and is typically matched with a 39 tooth inner ring. The 130 mm five bolt pattern should work with any 10 speed Shimano double crankset (Tiagra, 105, Ultegra or DuraAce) or SRAM.

The item is in Chino Valley, but if interested, I can bring it to my office near the Prescott Airport when I go to work. Please respond to this ad via email or text me at

if interested.
