Best type of bag for cycling with the MBP 17" (want to avoid infertility)

[hajime]

Hello,

I have been riding a bicycle between school and home.
Even I have a cusion on the seat, I often feel discomfort
in muscles between my legs due to the heavy weight of
the 17 inches model. I guess the backpack pushes the
spine colume straight down... I wonder if this could
eventually cause injuries or even infertility ...

Anybody knows if using a messanger bag could
improve/worsen the situation?

Thanks.

How long have you been riding your bike? it could be that you are using muscles you may have never used before. it also could be chafing, the seat is to wide, the seat is to short, the seat is to low. many things could be the cause and I doubt any are the MBP.

Hello,

It is a less than 20 minutes ride. I felt muscle discomfort
even on the first day when I was riding with the MBP 17".
(I used to have the Thinkpad X40 ultraportable. There was
no problem.)
