Worst retro mtb I ever owned was an Orbit but that really wasn't the bikes fault. It had obviously been custom built to some individuals weird measurements. Really short top tube, steep steering angle and could only squeeze in 1.75" wide tyres. I always felt I was heading over the handlebars even on the flat. It was however beautifully put together, lugged 531 with lugged unicrown fork and a black with white paint fleck colour scheme. I sold it on ebay and within 6 months the buyer sold it on ebay to. Definitely a bike only the original owner could love.
Sounds like the orbit helium road bike i had. It was nominally the right size for me (all the key tubes were the right length) but the horrendous angles filled me with dread anytime i needed to brake or turn.
By the time i'd got it comfortable, and the contact points in the right place it was only any good for riding in a straight line with no one else near you. It also weighed more than any other bike i'd even owned.
It was still better than the ribble it replaced.
