Has anybody ever had a Phil move sideways? It happened on two Jack Taylor tandems (both within CR timeline!), rear BB. We noticed the right-side chainrings were grinding on the chainstay, grinding hard! In both cases, the lockrings were VERY tight, but not glued in with Locktite. Same BB, both times, swapped from one bike to other. BSC thread. Drivetrain is standard: from the offending BB, the right crank has a chain to the rear wheel, left crank chain to front cranks. It happened within 500 miles of installation.
Is it a Phil thing, or a Taylor thing? I replaced the BB with a Ritchey (fixed cup), and no more problems. But I'd like to reuse the Phil, so I want to figure out what happened...
I NEVER COULD FIGURE OUT WHY PHIL WOULD SPEND THE MONEY TO INCLUDE THE LITTLE TUBE OF LOCKTITE WITH EVERY BB, NOR TO SUGGEST ITS USE. MAYBE WE NOW KNOW THE REASON.
WHERE MY PHIL BB ISN'T MOVING ON MY TRIKE.
