Does not include the hardware to install the short chainring, since the design has been changed to non threaded.

Easy installing without removing the crank.wore out original chainrings after putting 10,000 miles on the bike.

I was hoping this would fit on my 18 Diverge, unfortunately I was only able to use the larger ring due to the smaller ring holes not being threaded, probably should’ve done more research on the product

Holy cow they have great service and parts

Went on with crank still attached no problems. Had to use old bolts. Shifting still smooth need more time in saddle to see. It replaced a series one.

I bought this as part of replacing the group set on my 2009 Specialized Ruby Pro. Chainring still fits on my original carbon crank arms (thanks specialized for keeping things compatible!). Shifts quick and rides smooth.

Incredibly precise shifting says it all!!
