always check the threading on nuts and bolts and axels--- I am not a track expert---- I've built many ss's --
I would feel that chain tension should be "tight" enough-- no binding- I ride the streets--- bouncing and skipping-- I don't want the chain to come off-- I'd rather wear through a bb , a cog, a freewheel--- than fall--
running on a velo is not wilshire blvd! learn the tricks of the street and gear ratio, etc--- don't fool around--
