I know Ribble are not everyones cup of tea / coffee, but I love mine. All parts changed over from budget ally framed job with hideous welds, then upgraded bit by bit to the final version:
Ribble Sportive Bianco frame and fork.
Shimano 105 gears.
Shimano 105 crankset.
Planet X Ultra Light CNC brakes.
Provibe 7s seat post.
Pro vibe 7s stem.
Specialised Romin saddle.
Pro compact bars.
Exustar pedals.
Shimano RS80 wheels
Continental Gatorskin tires.
Karbonzone bottle cages.
Weight of everything including pedals, computer and bottle cages is 7.82 kg.

The frame looks like a Bottechiai 8avio from 2008/2009. Still have mine as my training bike / wet weather bike. In XL with DA 7800 and alu clinchers weighs in at 7.6kg. Pretty solid bike. Ride is a little harsh in comparison to my Parlee, but it is fine for rides up to about 120km.
Handling is good, and bike descends extremely well.
Enjoy riding it. There is potential to drop a reasonable amount of weight off. I could get mine down to 6.8kg relatively esily but at present it only gets lighter parts as and when I upgrade my

Cheers
Ozrider

The accumulation of marginal gains is what makes the difference between winning and losing

I love my Ribble, (evo pro carbon ) it's nice to see another on here! Plenty you can do to lighten it up, this forum has inspired me no end...I picked up some Pro lite bracciano's around 1400g for £285, not sure what your shimano wheels weigh but well worth a look if you like me are on a realistic budget.

I planned to get those when my planet x model b rear had a catastrophic failure but couldn't find any in stock or with reasonable delivery time, so settled for the Shimano - only about 100g heavier, so not much in the grand scheme of things. I think I can make significant savings if I can find a chain set that is good value (I'm a weenie on a budget) and good weight.
