Hey kids! When did tuff 1's come out? When did tuff 2's come out? When did they start making color tuff's? Thanks, Jason

Well, I rember Tuff 1 in the mid 70s, and the mid to late colors (red, blue, yellow) and Schwinn came with them in colors. There were (are) 3 versions on Tuff IIs, 1st gen T2,harder plastic, cracked very easy, steel hubs which also broke, 2nd gen T2, alloy flanges, back to closer too the origanal material, that didn't crack, the 3rd & I believe last gen T2 did away with the alloy flanges.
