I have a Phil Wood high-flange tack hub (fixed-fixed). It came with a beautiful lockring that has six notches in the ring. It is slightly larger in diameter that my Dura-Ace lockrings with two notches.

I have measured the diameters and they seem to exactly match the configuration of the Park Tool BBT-7.

• Not having tried it, I have to ask: does the Park bottom bracket tool (BBT-7) actually fit the Phil Wood lockring?
• Was that the intent of his design?
• Where can these Phil Wood lockrings be purchased?

don't know if it was the intent to fit park bb wrenches, but i've found myself having no problems whatsoever using a regular lockring wrench. phil lockrings are a big different than most other lockrings in that it has a flange that doesn't sit flush alongside the track cog, making it slightly harder to get a grip with a wrench on the lockring. not a problem whatsoever though if you're tightening right. phil lockrings can be purchsed through their website, but i'm sure other lbs's that sell phil wood bb's, hubs, will probably also have lockrings.

phil lockrings can be purchased on their site and at your local LBS through qbp. as far as i know the bbt7 will work fine. i have phil hubs and lockrings and i think thats the lockring tool i have.
