Chain Stay / BB Mitering

Chain Stay / BB Mitering

Originally uploaded by anthony.maietta

Yesterday I setup the Anvil chain stay fixture on the Bridegport and mitered the chain stays for A/ Correal’s track bike. I typically miter the chain stays below the centerline of the BB to reduce the interfernce with the bottom of the seat tube, but I really emphasized it on this one. Two factors contributed to this, the chain stays are circular at the BB on XCr ones and I wanted to reduce the clearance between the tires. You can see from the picture the offset miter. This does not affect the BB drop, just the angle the chain stay intersects the BB.
