Hi all, new to the forum...
After noticing the other thread on top tube height with respect to frame size etc. I did not want to stir the pot here, but I wonder about this issue as well.
I am in the market for a new bike (dual sport) having been out of biking in any meaningful way for about 30 years (age 53). At about 5'5" my choices in frame size are limited. I'm looking at a Marin San Rafael with either a 15" or 17" frame. At 17" when I flatfoot both sides the top tube is "right there" but when on the bike riding, it does not feel too big at all. The 15" give me extra top tube clearance but requires that I extend the seat tube quite bit and just seems small.
The "top tube" rule of thumb would suggest I go for the smaller frame and one of the key points of rationale, if I understand it correctly, is that when stopping, or in a panic stop, you would stradle the top tube and would need that extra clearance.
I'm just wondering, when stopping do you folks generally straddle the top tube and put both feet on the ground in most cases? I know when I used to bike I would typically leave one foot on a pedal, stay in the saddle, and balance with my other foot on the ground. This avoids the top tube clearance issue. Also, in a panic am I likely to hop off the saddle and stradle the top tube? Again, this would not seem to be a natural reaction for me.
Would appreciate your views.
