Hi all

I have a 1990 Trek 7000 in fantastic shape. I put about 2k miles on it and recently brought it in for the winter. I attached it to a water trainer i used to use with my jamis for years.

Long story short, i was riding it last night on the trainer for the first time and i guess i never had time to look down at my feet, but i noticed that the whole bottom bracket/chainring swayed maybe 0.25" each time i pedaled.

I will probably take it outside for a ride, and see if it "sways" on the street, but it is freezing so i figured i would ask here if this is normal?

many thanks
