Tony,
Here is the real issue, who could puts a triple on a Ridley Noah but the real truth is for randonneuring, this bike is unsuitable for anyone other than someone at the very front of the Vedettes on PBP who is on pain killers. Some 25mm tires won't fit this frame. This is an all out aero racing bike with the seatmast soup to nuts. Great bike. Just not a rando rig and this comes from someone who has been on carbon fiber on long rides since the 80's. I love carbon. This bike is not built for randos or comfort. Pure speed. If you find you like long rides, you will be selling this bike or buying another one. Don't worry there are plenty of used bikes with triples for sale out there. GL.
I'll let you know how pain I feel on a 12% climb on tomorrow's brevet with just a compact crank 34x28. If I still weighed 250, no way. Even at 205, it is going to be a real challenge.
