Tubing Choices for a New Build
If you were about to spec out a new steel lugged frame specifically for long-distance, mixed-surface-but-nothing-gnarly, light touring, and you weighed about 150 lbs and carried at most 30 lbs of gear in two small panniers on the rear and one large handlebar bag on a small front rack, what tubing would you choose?
The "Spirit for Lugs" looks appealing with oversized main tubes at 7/4/7 and a 31.7 HT along with oval chainstays and 16mm seatstays, but I'm worried it might be too thin for rough stuff with a load.
Would you go oversized with 8/5/8 wall tubing or standard sized (1" TT) with 9/6/9 tubing? I built up a frame with the latter tubing about 5 years ago, and while it's super smooth it gets a little noodly when loaded.
The frame design will be 58cm square with a 1* sloping TT, 72* ST & HT, 5.3cm rake, 45cm CS.
Thanks for your input.
