the ‘road-like’ position you describe may not be great for long back to back days
Well, I’m really thinking of three bikes – my old Orange P7* (23″ top tube, 130mm stem etc); my current road bike, and my 07 Kona Heihei (FS, 105mm stem), all of which have done plenty of long long days and feel** a lot more positive and efficient than my other FS bikes which are of course better for technical stuff. Of course something like a Stooge could be just fine too but I don’t really have the luxury of trying all the alternatives, particularly as I’m not buying a full bike. All I can do is take a punt.
You’re right of course that eventually it might become uncomfortable, but I feel that the Stooge in particular is less conventional than the others so might be harder to adjust to all purposes.
Re durability – are steel frames really any more durable than CF? As for saving 2lbs in gear – of course, but gear will be minimised as well. However, given the other duties the bike will have to perform as well as the TDR steel could be the way forward.
I’m beginning to doubt if I’ll ever get to actually do the TDR though.. it’s a big ask of the family..
* sadly nicked
** feel being the operative word – never done a proper test to see if the riding position really makes a difference to overall speed
