    Default Tubing Choices for 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.

    Has your framebuilder shared his ideas and opinions?

    As you are commissioning your builder's expertise and experience to make your frame,
    then one hopes that he or she will explain the rational of their tube choice for your bike's intended use.
    I think it is best to speak to them.

    OS Spirit for lugs is .74/.45/.75 main tubes. (but they did make a .7/.45/.7 for some short length top tubes )
    Generally speaking, increasing the diameter has a much greater effect on the rigidity of the tube than upping the wall thickness.

    Let your builder fit you, tell him/her how you intend to use the frame, and then think happy thoughts for the next several months while it's built.

    I have to agree with Dazza and Bill. If you're going to look over the chef's shoulder, you're better off eating at home. But if you've done your research and picked the right guy, your expectations should be met or exceeded.

    Sorry not to be clear about that. I am the builder! I have five frames under my belt, so I'm still new to this. Just looking for some overall opinions. Thanks.

    then try/use PegoRichie (aka spirit for lugs) atmo. we have 5 hard seasons of 'cross use on it and the last 3 have
    been on the lightweight version. only one dented tube and that came on the last lap of the last race at the natz
    this past december.

    I weigh nearly the same as you plus your 30 pounds of gear combined (but trimming down, I promise). I've ridden hard on the PegoRichie lightweight stuff - no worries at all.
