Saddle hurt, saddle sores

If the top tube was longer on your previous bike, it probably moved more of your weight off your arse onto your wrists which might help with arsesoreness, though obviously with corresponding disbenefits in handsoreness. Also, talking of weight, you're pretty slim - maybe some additional pies would help with internal padding?

Oh hey, you're right. My hands did hurt more on the other one. I think really the problem is a) yes, I need more butt padding, and b) it's just the speeding up, slowing down, speeding up, slowing down of my commute and the hills where I'm all whooooooooo down them that makes me rock around on the saddle. My NYC commute was pretty sedate and when I do the full one here I quadruple that one.

But like, I'm an asshole, I pretty much eat what I want as it is. High metabolism, it's why I'm such a hyper so-and-so, I guess.
