Weight reduction - stock SuperSix 105 '12

Hello BR!
I have a bone stock Cannondale Supersix 105 2012 model that I'd like to lighten up a little.
Where would you start - Bang for buck wise?
I'm guessing the main weights of the bike are the Aksium wheels and the FSA crankset?
What would you change - and what parts would you replace it with?
Sensible budget of max £400?

Well, nothing wrong with lighter/smoother wheels, can make a bike more enjoyable to ride but won't make you measurably faster.
Any other upgrades, do for comfort.
Mavic Ksyrium Elite S - 1520g - £450ish
Shimano RS80 - 1520g - less than £350
Fulcrum Racing 3 - 1555g - £400
Wheelsmith Race23 - ~1440g - £450
etc.
You can drop 300+ grams where you're going to feel it the most.
Shimano RS80 - 1520g - less than £350 - Hell No
Fulcrum Racing 3 - 1555g - £400 - Err, No
Wheelsmith Race23 - ~1440g - £450 - Not too bad actually
For reference I'm 84-85KG (13 stone 4lbs) - When I'd bought the bike I was above 15 stone.

lol, of course.
Anyone know what Aksium's and the stock tyres and tubes weigh in comparison to something like the RS80?

Don't always assume Smidsy knows what he's talking about
aksiums are 1795g, RS80s are 1521g... but that's without tubes, tyres, and skewers.
How very dare you
I got some old school cycling plus's from 2010 for you Smids, cannondale supersix was bike of the year, Harry Rowland's wins wheels group test etc - this was of course before the editors sold their souls to the devil riding in on his Giant Advanced Defy shod with Mavic wheels
Oh, on behalf of Smidsy, OP - Have you considered Handbuilt wheels?
For £400 a good wheelbuider should be able to put something together that will suit your own personal needs - Ugo is a good man on this forum to provide such advice.
Love it though, great bike....
If you are less than 85 kg then DT Swiss RR415 28F/28R on Novatec A291/F482 hubs with Sapim Laser spokes and alloy nipples is 1446g. I ride a set similar to these but with Miche hubs (heavier) and stiff for the weight too. You could go for the 32H rear rim for the extra stiffness. There are more aero rims though if that is your thing then CX-ray spokes would help a bit.
If you a a bit lighter (I think no more than 80 kg) the Kinlin XR200's on the same hubs work well. I again ride a set and they feel fine. These weight 1362g. To make the rear wheel stiffer a 32 spoke rear wheel could be used as 32H XR-200's are landing soon.
For a durable lowish weight wheelset. Velocity A23 rim 24H front and A23 off centre rim 28H rear with Miche hubs and CX -ray spokes (or laser spokes with alloy nipples). It should be fine for riders up to 85kg (but riding style will influence this). Wheelset weight will be ~1595g. A 28F/32R wheelset would of course be suitable for heavier riders or riders not kind to wheels. Also thicker guage spokes would suit some riders better but add weight.
For a semi aero set of of wheels the H+ son archetype on a light pair of hubs, like Novatec A291/F482, Ambrosio Zenith (which are rebadged novatecs) or Dura ace hubs would make a good 1545-1700g wheelset depending on the hubs and spokes used.
There is also the Kinlin XR-300 which is as far as I understand the same rim as the IRD aero on wheelsmith wheel page. this rim is 30mm deep and available in 20 to 28H drillings. A 24/28 spoke wheels set with these rims would be very stiff and suitble for many riders. A set built with CX-ray spokes (or laser spokes with alloy nipples) would be about 1520g.
All of these wheels would be preferable in my eye's to a factory set and they all do the wheel thing slightly differently. They will also perform better in more ways than just having lower weight than the askiums but that does not mean you should ditch your current wheels. So long as they are round and straight and stay that way then your Askium's are still doing there job of being wheels.
The velocity A23 on Miche hubs or the H + son archetype on DA hubs would suit the vast majority of riders and cover two ends of the budget spectrum.
In all cases wheel stiffness can be improved by sing thicker gauge Sapim Race spokes or ACI Alpina DB spokes with a weight plenety of course.
You've ridden all of these then?
Ride them, why would I want to do that
I'd go for veloflex master tyres, latex tubes and ksryium elite or hand built wheels
So you can finally realise that Elites are a pretty nice set of wheels

For everyday riding then yes, probably not as capable of helping you hold higher speeds on the flats but that's from recollection. Both nice wheels though. The 420 aeros are proven to be as good as most so called 'aero' wheels that have a 50mm+ rim depth. Just not sure how that translates into real world performance for mere mortals though....
The 420's are stiffer IIRC.
The thing I upgraded that made the biggest change to the way the bike feels has to be the wheels/tyres though. I now have a set of Planet X 50mm tubs (that I use for racing) which weight 1400g and they have made the bike noticeably faster. Previously I had the original set of RS10's on, and compared to those it's like a new bike. Admittedly these wheels aren't so much of an every day wheel, but something like the RS80's with an open tubular tyre and latex tubes will get pretty close to the same feel as my tubular wheels with everyday practicality.
So yeah, if you're spending £400 just now then change the wheels/tyres first, then you can work on the rest of the bike over time.
So, not really talking from experience then.
You'll get a life experience you will always remember and shed some weight 8)
Job done
Well, that's what I would do.

They reduced the weight by 2.3kg, and I think it only cost somewhere over six grand. Bargain!
