Thank you OFG for the excellent information. I'll feel a little less guilty riding around on my oldest son's 1988 Montagner. It is made from Oria 0.9 which I always thought of as a lower quality steel compared to the higher grades in my steel bikes. The bike's geometry makes for a quick reacting, hands-on ride. I even enjoy using the older Suntour components. They shift beautifully and are easy to maintain.
