I'm a novice at commuting via bike. Heck, I'm new to cycling in general. I recently bought my very own bike in May. It's a specialized globe sport. I loved it for the summer when my commute was 5 miles one way, but I don't particularly like it for my current commute for 10 miles one way in SF. First, it's a bit heavy hauling it on bart/transbay (I live in Berkeley), second the upright position is uncomfortable and starting to hurt my elbows.
I'm looking for a lighter and more efficient bike. Any suggestions? Road/Touring? What do you guys think about felt alternative road bikes? Are the thin tires ok for the crappy streets of SF?
Any suggestions would be greatly appreciated.
