Just surfing for (bike) porn and came across Ribble cycles.
They look like sex on wheels but do they really come up to scratch for the price-almost £200 below anyone else for a tri spec bike?
Just through interest, when you search for bike porn, what do you type into google.
don't know about their tt frames but a chap at work has a ribble road bike with carbon forks and stays on and he loves it.
While you're surfing for surprisingly cheap Hardon-Fibre you might also want to check out Dolan. I'm pretty certain they get their Carbporn frames from the same factory as Ribble. See also Planet-X. Same supplier AFAIK.
