Hello.

I currently ride a 2007 Bianchi 928 full carbon bike, which weighs 8.5kg in total.

The time has come for me to upgrade, and I want a full carbon road bike at 6.5kg.

I am keen on the new Bianchi Infinitio and Sempre frames. Oltre frame is just a little out of my budget.

Anyone know what the weight of the 2012 or 2013 frames weigh (including fork)?

I love Campag and willing to buy the top of range 11speed Super Record Groupset.

What components would you recommend I acquire to achieve this weight of 6.5kg?

Vastus


OP: please give people a chance to reply.

Thank you, Admins.

According to Competitive Cyclist, the frame weight of the Infinito is ~1170g, with a ~365g fork. Sempre is ~1120g, with ~315g fork

With full super record you're going to have to kit the rest of the components out as full carbon cockpit, light saddle, and probably some light tubulars.

I suppose you could do it with some ~1.4kg clinchers, but you'd have to drop weight elsewhere.

It really depends on what your budget is. To get full SR + ~6.5kg you're probably looking around $7-9k.

The Infinito (2012) is probably a bit lighter than that. My dad's one (Size 59) comes in at 6.8k on the button with heavy bar/stem/saddle and Kysrium Elites. Probably struggle to get to 6.5kg without tubies or light bar/stem/saddle/post though...

I'm new to these forums and not a weight weenie, I'm more into ride quality.
Like most people though I don't want to cart around excess weight if I can help it.
I look at some of the weights posted on here and compare them to my bikes and I'm miles off.

My Sempre weighs 9 kilos 19lbs with pedals, cages and speedo.
I can get it down to about 8.2 kilos by swapping out the wheels to my Stans Alpha's.
It's got Deda Zero 100 bars and stem, the rest is stock, looking at it I can't seewhere I could save much weight.
Maybe the FSA Gossamer crank, but that's about it.

if you want to cut weight, start by making a list of all the bits, exact make/model/size, then check the weights

once you know where the weight is, you can look at options and weight/cost/performance impact

my xcr (with steel frame) weighs 7040g at the moment, i'm sure the frame must weigh much more than the sempre does

but the saddle and seatpost together weigh 201g - if i weighed less i could use ever lighter ones - i'd guess your saddle alone weighs more, on the other hand, the integrated bars weigh 466g, but i really like them and the stiffness justifies the extra weight

so it's a matter of looking at each part and deciding where you can save weight in line with the performance/features you want

it's what spreadsheets were invented for :-)

How about the Columbus Genius carbon frame. That is meant to be 960g. Carbon tub ~25mm deep could be built to around 1kg. Using the right hub clinchers in the 1.3kg realm or a bit less a viable. It will cost though. You could save moeny by buying your group second hand, The wheels don't have to cost the earth unless you go for thos Enve tub rim @250g and light tune hub like the Mig45 and Mag 150.
