I have an opportunity to buy a used, well taken care of Ridley Helium 2008 frame in my size. I have been looking at the kestrel (new) for quite some time and wanted to get some thoughts. The Kestrel has internal cable routing, it is 950gr vs. 900 for the Ridley. Not sure about stiffness for the kestrel, the Ridley I understand is quite stiff. I am currenlty on a Talon and like it, although it is not as stiff as I would like. I will be using for group rides with quick sprints at the end. Cost is close between the two. Thanks for any help.
