Well, I still use my Schwinn traveler 12 speed roadbike I had since 1990…They were still made in the USA back then… The frame and fork at least. The cranks, gears, seats, brakes were all shimano already i think.
I never got a mountain bike. Sort of want one now…
With all this software shit I normally do, I admit I wish I had the means of starting some small times niche manufacturing gig in the U.S. I do get all giggly seeing folks push the limits here.
