I think the adjustability would not be key for me. Once I find a setting I like I will probably leave it alone if I indeed get an SLR6. The bigger deal is probably the better carbon. That would be the draw for me as well as the better wheels.. I am currently riding an Aluminum Trek 2.3 with carbon stays/fork/handlebar. I imagine a new carbon bike will be quite a bit lighter. I love the 2.3 and over the years have upgraded it to mostly Dura Ace components. I really like it but want a new bike. I will have the money for an SLR6 and will order a new road bike sometime in January or February. I actually have the cash now but with the end of summer approaching I figure to finish out the season before making the investment. I would also like to build a new mountain bike so instead of buying another motorcycle I am investing in bicycles !!
