As I've aforementioned elsewhere,
Ribble was on my shortlist last month for a new road bike. I even managed to find an owner of one in another department at work (fortunately a similar height to me) who kindly lent it to me for a morning to thrap.
I didn't go the Ribble route in the end as I felt the front end was too flexy for a lardo like me - under mega hard mid gear pedal stomping I could see the main triangle flex. Old fashioned tube manipulation and a non tapered steerer didn't help. Shame, because it was a nice fit and comfy too.
Any way, to the point. I ended up with a rival brands bike with full Tiagra for £300 less than the comparable and bendier Ribble with full Tiagra. Can't see how that makes Ribble to be good value.
