I have a B.O.B. Yak. (After wrecking the stock hub) I rebuilt the wheel with the stock rim, custom cut DT spokes and a BMX hub that bolts on with 8mm allen bolts. The fork has been replaced too, because the original got bent somehow. I think someone backed into it while I was locked to a parking meter. I'm glad I have the new fork. They improved the design. Anyone having problems with the connection of an older BOB trailer to his or her bike should take a look at the new improved fork.
