This is a scarce mountain bike around here at least. Rodriguez Bicycles, in Seattle, makes their own racing and tandem bikes. They imported some touring and MTB models in the late 1980s using the Terre Tech brand name. This is a 1989+/- Terra Tech Trailite Pro.
The bike was built in Japan by Koizumi. I believe Koizumi made some of the nicer Japanese Centurions.
I bought this at a LBS, probably paid too much for it. But I am a sucker for Deore XT components, Tange Infinity tubing.
