They still make quality bikes. The Tyax Expert is a pretty good MTB for $800.
The name just got trashed as soon as their lowend bikes hit Walmart's shelves.
For MTBs they were really cool looking chrome but heavy in the mid 80s.
Late 80s, barely into the early 90s they were still heavy, but got short chainstays fairly early on compared to other mainstream brands.
1996, the IBOC Zero G came out. $750 MSRP for a sub-25 lb MTB? Amazing!!! I couldnt' not get one. I waited 'til 1997 to get a closeout one for $600. Been riding it ever since. Got it down to 24 lbs even with some cheap upgrades.
