What is the best steel tubing presently available for building a century bike (for keen recreational riding, not racing)?

The bike I'm planning will be about a 52 cm sized bike, with a squarish build, sloping top tube (in the 4 to 6 degree range) and with the TT, ST, DT's built using standard sized (1 1/8" to 1 1/4 ") tubing. The final built-up bike will probably come in at about 19 lbs (or somewhere in the upper 8 kg range).

I'd like the bike to have a bit of flex (for a 165 lb. rider) and be comfortable for longer rides. Something that is not too delicate and will be around for a while given a reasonable level of care. I am willing to sacrifice light-weight and stiffness for durability and comfort (if we are talking about ~100 gram weight differences).

I haven't decided on the construction, probably fillet brazing rather than lugged, and most likely with a powdercoat finish.

Any suggestions or links?

Just about any of the medium thick OS tubesets would fit the bill. A few that come to mind are Columbus Zona or Spirit for Lugs, Dedacciai COM12.5 or ZeroUno, TT Platinum or Reynolds 853 with .7/.5 or 8/.5 (short) butts. You can go down to 0.4mm but the frame will be more fragile with regard to handling damage.

Hope this helps.

A lot of UK audax/rando builders use Reynolds 631 for the long distance (audax) bikes. I would use that as a starting point :)
