Hey everyone,
As I'm not the biggest tech head going around in terms of bikes, and my research efforts have been fruitless, I'm needing help comparing the 2010 105 groupset to the 2012 Tiagra.
All I know so far is that they are similar in technology, but am needing more info regarding weight differences etc etc as I'm looking at purchasing a 2012 Specialized Tarmac and subbing out the Tiagra for the older 105.
Cheers
