Picked up the Jamis this morning. It definitely felt like the right bike at the right price. although once i said yes I was a little disappointed with the LBS service, no additional fitting or tuning done at all. The seat was approximately adjusted before my test ride. I do get a free tune up in a months time and I guess once I have been biking a bit I can make some adjustments to the seat etc.
Tried a couple of carbon frame bikes and they certainly rode nicely but I would either have to drop down to Sora/Tiagra components with cheaper wheels, or fork out another $500.
don't have pedals or shoes yet, REI have a 25% discount on Shimano pedal/shoes starting Friday, plus I can get another 20% off a full price item like a helmet. This suit me becuase I don't want to touch the bike before my marathon.
