If it's not Motobecane doohickie thingies, it's something else! Let me start with three challenges this weekend brought. Any feedback, suggestions or advice welcome.

1985 TREK 560 - Picked this up yesterday in very good condition, not a lot of miles. In the process of doing BB maintenance, I pulled the Suntour Cyclone double crankset off and removed both Sugino sealed cups. No rust or stress on the cranks or bb, but note the fixed cup chipping. The vinyl gasket fits between the groove shown. Will it matter if I use a non-sealed set of cups? It appears that the vinyl gasket makes the bearing surface protrude deeper into the BB shell than a non-sealed cup. BB measured 115mm.



MOTOBECANE GRAND TOURING - Stronglight 93 crankset with normal crank removal tool threads and 9/16 X 20 pedal threads. Adjustable cup takes JIS 1.37 X 24 cup, but I'm used to two flats on the drive or fixed side. Any guesses if this is righty loosey? it's rusted really well.



RALEIGH OLYMPIAN - Huffy era. The fork steering tube seems to rattle around, no matter how tight the headset, and if I tighten all the way down it binds. Should I just replace it or am I missing something? It is the lock nut, the washer with notch, and the ring, which is an unconventional almost flat one, versus one that typically covers the upper cup.
