In reply to The Potato:
I've got four road bikes - one aluminium, one carbon, one stainless steel and one steel. All bar the latter have carbon forks.
The aluminium one is an 'adventure'/commuter bike and is solid. Nice to ride but unremarkable.
The steel one is a fixie and has a nice feel, with a definite spring to it. Quite heavy
The carbon one is as stiff as they come - you feel every jolt. Light at just over 7kg.
The stainless one is also really stiff but absorbs a great deal of the vibration etc that the carbon one does not. Also light at 8kg
The stainless one is the nicest to ride - which is just as well given its price tag.
