Specialized has just launched a Micro-Site just for the new 2010 Tarmac SL3.  Other manufacturers may not like it, but there are lots of weight, stiffness and other comparison charts that show how the new SL3 stacks up to bikes from quite a few other brands.

It’s a pretty thorough site, and if you comb through it, you’ll see that Cancellara was riding a prototype (pic after the break) in this year’s Giro d’Italia, but it was painted like an SL2 to keep prying eyes from suspecting anything…
