Sometimes I wish I did! ;)
I keep hearing about that sitting to standing transition.... I ride either way, when I need too, but I guess not enough that it is becoming bothersome, I dunno?
Its kinda like that "arm pump" thing I keep hearing about. I dunno what the heck they are talking about..... I may have carpal tunnel, my hands tend to go numb, especially at the start of the ride or on long down hills. When riding with CC I tend to get numb up to my elbows! He likes to ride! ride! ride!..... While I'm more like: ride, rest, ride, rest, ride, rest,...... ;)
