    I bought this for a 226mm bracket and found mine to have a slight difference in OD of the main steel shaft and where it changes to aluminum and enters the bearings. In order to seat the adapter in close enough to align my chain I used a slightly larger drill bit to bore out the one side. Aside from that it looks and works great. The threads aren't the tightest so use some blue loctite and you're all good. Excellent product.

    ChainRing Adpater 1 from SBP was better than I expected. Finish was very smooth and it fit on the 5/8" jack-shaft perfectly. Kit even included keyway bar, set screw and allen wrench for set screw. I would purchase again from SPB.
