Keep in mind that these tubes are OS, so the 8/5/8 will flex similarly to a
9/6/9, and the 6/4.5 would translate roughly to a 7/5/7 in terms of
measurable flexing properties. It of course matters more when you are
comparing Rivs to vintage standard tubing steels like 531, Columbus SL,
Ishiwata 022 and Tange Prestige.
I kind of get the planing thing, but I'm not convinced that tubing of the
main triangle is the main reason a bike will feel good. Tires as we know
makes a big difference, as do lots of other factors that add up. Bottom
line for me these days is, I'm pretty easy to pleasy.
