merlinextraligh - let me ask this then, at what weight difference would you consider it worthy of upgrading your bike if you simply wanted to help improve your pace?
I know this is comparing apples to oranges but when I switched from an MTB to road bike my pace improved dramatically given similar conditions (I was riding the MTB on the road). Now that I'm on an actual road bike I'm trying to ascertain at what point it makes sense to upgrade to a newer bike provided that I'm as well conditioned as I can be physically. The most logical thing for me to first consider was the weight of the bike but I'm sure there are other factors as well.
