What sort of fitting session lasts for four hours?
There's a shop near me (Westbrooks) that does a Guru bike fit. Has anyone tried that?
I had a 1 hour test ride (all I had time for in the end) of a Roubaix with Ultegra. It seemed very comfortable compared to my bike, with the surface of the roads I took it on being less than perfect.
I chucked a leg over a Synapse in a shop but didn't get chance to ride it. Think I definitely need to have a proper ride of everything, really.
