Hello Everyone,

After reading so much on the forum I finally decided to make an account :)

I got a Bianchi Specialissima and would like to make it under 6kg, right now the weight should be 6.6 - 6.7 kg.

Where do you think I should start? I got a SR crankset on my Oltre Xr4 with Favero Assioma Power Meeter, should I use that to save some weight?

Bianchi Specialissima 57 cm, color CK16 Opaco
Campagnolo Super Record
Campagnolo Bora Ultra Tubular
Cassette : SR 11-29
Tyres: Tufo Elite S3
Seat pin: FSA K Force Light
Saddle: San Marco Aspide Carbon FX
Stem: FSA OS-99 CSI STEM
Bars: FSA K-FORCE NEW ERGO CARBON
Bar tape: Not Sure
Pedals : Xpedo Trust 8 Titanium (173 gr)
Power Meter : Power2max Ngeco
Crankset: K-FORCE LIGHT BB386EVO
Chainring: Rotor Carbon 52/36
Cages: Elite Rock Carbon (27 gr each)

Suggestions are welcome :) And by the way, I would prefer to keep it as Italian as possible

Your wheels and frame are pretty light. I would use EE brakes, Extra Lite Stem with 3T Superleggera LTD bar, Berk saddle, Tune bottle cages, and SR crankset. Perhaps a Darimo seatpost too.

Where would I save most of the weight? What are EE brakes?

Some potential stuff:

Skewers: Extralite Streeters: 29g

Cables: Alligator I links or Power cordz

Saddle: Berk Lupina: ~70-80g

Seatpost: Darimo: ~115g if you want a setback

Brakes: THM Fibula (120g) or Cane Creek EE Brakes (~170g)

Cockpit: Darimo Ellipse and IX2 stem: Possible to do a little over 200g depending on the combo you choose.

What I'd recommend doing is making a list of all the components on your bike alongside their actual weights, or claimed weights if you don't feel like taking things apart. Then you can start making a list of all the lighter parts you could swap out, figure out how much weight you would save, and then divide that by the cost of the upgrade. That way you can prioritize in terms of dollars per gram saved.

Typically speaking, skewers, tires, headset, topcap, and cables are going to be your cheapest in terms of $/g, depending on your starting point.

Then you have more expensive ones. But with the potential to drop some significant weight. Brakes, your saddle, post, and cockpit all have lots of room for weight savings but at a higher cost.

And then probably the single biggest potential weight saving area which is going to be your wheels, but that comes at a cost. Going to something like Schmolke's TLOs would let you keep the overall rim depth you currently have in a wheelset that's around 1000g. Or go to the TLO 30s and you're talking about a ~900g wheelset. Or Extralite's carboclimb 25s, which would put you under 800g for the wheelset.

Start from the seatpost, handlebar and stem. Good amount from there. Deda Traforato handlebar tape weight like 22-25 g and it's really cheap.

Keep those SR brakes but just modify those with lighter brake shoes, ex. KCNC. Don't get Fibulas if you like to have good breaking.

Berk Lupina padded saddle weight little over 100 g. Just use whats fit for you.

Maybe lighter skewers but I would stay with ~40 g+ for safety and to have good rear wheel holding while sprinting.

Get lighter bottle cages with alu bolt. SR crankset + Favero should save same weight. Weight the seatpost clamp, headset and computer mount.

I would start with these before going to more expensive stuff.

seatpost kforce light ~190g --> any schmolke/darimo/mcfk setback post will be around 100-120g for ~350mm
saddle aspide 147g --> unpadded schmolke/selleitalia/berk/tune ~60-70g /padded berk/tune/mcfk 90-100g
stem fsa os99 ~135g@120mm --> darimo 74g
bars k-force ~185g@420mm --> darimo/schmolke/mcfk 130-150g
cages @27g/piece --> carbonworks 8g/piece
braskes sr single pivot rear 270g --> eebrakes ~190g incl pads
expander ? @30-40g --> ultrastar 6g
seatpostclamp ? ~20g --> darimo/carbonti/procraft 4-9g
tires tufo elite s3 225g --> calibra+ 180g
in line barrel adjuster campagnolo ~6-7g --> jagwire pro mini 2g
garmin mount ? --> carbon works mount for darimo 12g
bartape ? 30-50g --> deda traforato 25g

total ~550g saved

skewers seem to have a carbon lever already so probably on the lighter side

not sure about how much sr crank will be lighter

highly controversial but removing paint + adding clearcoat could save 50-100g

only other way to shave the last 200g without sacrificing rim depth would be schmolke tlo 45 with extralite hubs

Thank you all for the replies! I'm learning a lot of new things about the bike components.

Going to make a list with the parts suggested and see how much it would cost me to shave 600-700gr

My additions
- Corima cork pads
- powercordz swift cable set
- tesa tape for bars

The Carbonworks garmin mount is 3g lighter than my raceware mount but is almost 5x more expensive so I strongly recommend the latter.

The price of a second bike :)

You're not wrong. Once you get beyond the first few hundred grams of low hanging fruit, it gets real pretty quickly in terms of $/g. And continues to get more and more real the further you go. To the point where you eventually find yourself considering a $2k wheel upgrade to save 100g.

Surprised it is not already lighter, but make a list of components and we will see:) you should not probably go the lightest possible way as it may transfer your bike into somewhat uncomfortable to ride..but make a list and then you will see what others suggest..Darimo and Mcfk components are quite reliable, i would not put there the lightest possible tyres for example..

That's a really good point. Some weight losses don't come with any tradeoffs other than cost. Some require a bit more sacrifice. Your lightest possible tires you're going to be dealing with decreased puncture resistance. You can save a ton of weight off a cassette by going with some boutique weightweenie options, but there's going to be a durability trade off. Same with Fibrelyte chainrings. Some lightweight brakes lack the stopping power of the larger manufacturers, while some perform very similarly. Some people will argue that truly lightweight saddles come with a quality of life tradeoff, though personally I don't buy that one as long as the saddle fits you (I've done 200 mile days on my unpadded Berk Lupina without any pain or discomfort).

Seatpost, stem, handlebars, wheels, cables, skewers (well, most of them) there aren't any real tradeoffs.

Wheels you can go either way. You might sacrifice aerodynamics to get the lightest option possible by minimizing rim depth. You might sacrifice service interval if you go with ultra lightweight finnicky hubs. You might sacrifice some day to day practicality by riding tubs over clinchers.

The lightest possible bike comes with some drawbacks. It's always a delicate balance, trying to get as much weight off your build as possible without making it wildly impractical to ride.

Is darimo a good brand? I never really heard much about it.

You guys don't suggest THM because it's expensive?

I'm thinking to start with the Seatpost

For a really lightweight seatpost, this is a good option. Its considerably cheaper than the likes of THM, mcfk, darimo.

Comes in 3K and UD
