Long story short: I've been riding a pretty standard/cheap single speed for the past year, but recently upgraded to a slightly better quality bike. The frame on this is a 4130 steel lugged frame. Here are the rest of the components if interested: http://www.bikesdirect.com/products/se/premium_brew.htm
Here is the old bike: http://www.torkerusa.com/bikes/commute/2012-udistrict
What I am curious about, is why does this bike ride so much better? Also, what components affect this most?
For instance, if I upgraded my seat post, will it make the ride any smoother? Will bumps be less obvious? Aside from looks and weight, what are other advantages of a nice seat post?
Other ideas are great too!
