The more I ride my Premis and it feel like I'm riding on silky smooth road.
Ah. Columbus Tenax used by Schwinn in the late eighties is the three main tubes only (top tube, seat tube, and down tube), and it's double butted (except the seat tube, which is straight gauge) seamed 25 Cr Mo 4 chromoly alloy, which is a European standard almost identical to AISI 4130. Columbus Cromor is also 25 Cr Mo 4 alloy. The welded seam in Tenax is very homogeneous so that after drawing and butting the tube is virtually the same as seamless. Here's an email exchange with Columbus about Schwinn's Tenax tubing:





SLX is fabricated using Columbus Cyclex alloy which is slightly stronger than 25 Cr Mo 4, and has the helical reinforcements in the butted ends of the down tube and the BB shell end of the seat tube.

Did you change out the original fork? What to?

Honestly I am worried I'll regret selling it too, which is why I've held on to it so long. In a way I think of it in the same way as some of those bikesdirect bikes- an underappreciated bang for your buck deal, but missing the heritage and framemaker's integrity.

I did not, and it was harsher than some of my others. Yet it was also so fun and with a Brooks saddle that I honestly couldn't get far enough back it was still comfortable for lots of miles. I sold it in one of those silly moments when I thought I had too many bikes. Like that can ever really happen.

My night time rider is a 78 World, imported from Giant, and made of Femco 1207 hi-ten. Comfortable enough, but not what one would call responsive.
Actually the 84 Le Tour Luxe was beat in 85 by the Letour Luxe which is the one I have. The 84 was the lower quality 4130 cromoly which was the same tubeset the lower end LeTour, Traveler and World Sport all used; the 85 was the Tenax tubing and the regular Letour, Traveler, and World Sport still used the 4130. The 85 LeTour luxe was designed as a serious touring bike that shared the same frame as the 85 Voyager and some of components as the top of the line Voyager SP of that year, the only real difference in the frame components was the fork, the LeTour Luxe used Tange hi tensile fork and the Voyagers stepped up to either Columbus or Tange which cut the weight of those two by about half a pound, in 84 the LeTour Lux used just regular hi tensile fork which weighed more than the Tange. All in all the 84 Le Tour Luxe weighed 2 1/2 pounds more than the 85 version.
