Soft tails
Trek did the STP range, 200, 300 and 400 which was effectively the 'Team' bike.
It was originally a Gary Fisher bikes but swapped to Trek for full production.
I seem to remember that Lance Armstrong won an MTB race on an STP for the Trek team as a warn up before returning to take the first of his 7 TdF wins?
Carbon works quite well, steel is quite springy naturally, as is titanium.
I have a KHS STP Comp (steel) and a Trek STP200 (carbon), so I need a titainum boke to complete the set :!:
Both of mine date from around Y2K.
Schwin did some fairly run of the mill ones about 10 years ago, and just remembered Airborne did the Paka Wallup to add to the list.
