Touring size specs. measured as..MTB or Road?
I'm buying a bike in Japan, and this is a country without much in the way of biking.
One company sells touring specific bikes..... via a catalogue. The bikes have 26" wheels, and drop bars, with the shifters mounted on the frame.
They come in three sizes.... s(38cm) m(46cm) and l(50cm) which is tube length.... however, the heights suggested for these sizes are as follows:
So - it looks like these are metricified MTB sizes. These are steel frames with 26" wheels....
My question is, are these sizes really a good guide for touring, as the frames are going to be quite smaller than road bikes.
For example, I use a 50cm road bike, and I'm 164cm tall. This catalogue would have me riding a 46cm frame.
Is it better, (and I know this is probably a personal thing) to have a smaller or larger frame for long distance riding?
