Challange; to lighten my bike 1kg

[Skorp]

Hi!

I have this old cannondale. What parts would be the cheapest to replace to save 1kg?



Cannondale CAAD 7 R700 frame
Cannondale Fire stem
Shimano WH-R550 wheels
Shimano 105 gear system
FSA Gossamer crankset

Wheels - those Shimanos are heavy, 1884 g, replacing them with something like Fulcrum Racing Zero will save 450g.
Next are tyres and tubes, you can often save well over 100g and potentially up to 300g b changing to lighter tyres and tubes without sacrificing reliability and improving ride quality substantially.
Often pedals, saddle, bars and stem are easily replaced and can save many grams, cables and bar tape can save 50-100g, and seat post clamps, can be replaced with lighter versions cheaply. Skewers are another item that can save 50g or so changing to KCNC or other light skewers.
105 groupset is pretty heavy at over 2600g, so by finding a good second hand SRAM Red or Dura Ace Groupset you can drop 500-600g

Wow, didnt know the wheels where that heavy, they feel like cheese aswell..
Im thinking of 38mm China carbon wheels. Tubular. Does tubular save anything compared to clincher?
I'm thinking China carbon seatpost and cut it as short as safely possible.

I want a shorter and a stem with less angle, is there any relativly cheap stem that doesn't cost too much?

My budget on this lightening would be around 700-1000$, so i cant really go all out on this! I cant even afford the wheels you are thinking of.. They retail at more than i paid for this whole bike years ago..

Tubular will save about 100g-200g (per wheelset) compared to clincher in carbon. There is often some additional savings in a tubular tire vs. tire + tube.

Search for this type of stem on ebay and you will be plesently surprised at price and weight

Not sure where you're located but $1k + eBay + a little patience = a lot of weight loss. As said, wheels are the main culprit, closely followed by the fork and crank.

New bike. Not totally worth the investment unless it's a set of wheels that are transferable from bike to bike.

13.6lbs as shown (13.5 at present). Pretty much an eBay budget build.

May be obvious, but invest a bit of time trolling this very site for ideas - there are a lot of smart people who have done some cool things here.

Don't rush into anything - think about what you want to do and why. Weigh the cost / benefit (gram saved per dollar) of each change you make. And above all, be *patient*. Craft a vision and execute - see Prendrefeu's bike for an example of how to do it well...

Oh, and have fun doing it!

You can get a bargain priced but high quality wheel set from Boyd Cycling for about $600 that weighs about 1500g- not super light, but a lot lighter than what you have. As others said, used or last year's models of components on ebay can save a lot, as can buying from the UK mail order houses (probikekit, ribble).

Are you talking about used parts?
I live in norway.Buying from private people on ebay is a bit of a hassle, altough if the price and part is right.. then it's no problem

I think i can get my bike spec vise better than a bike for my budget on 700-1000$..

Like the 64grams duraace, only a cheaper version

Does the modification have to be cosmetic as well (make the bike look nice) or you just want to loose weight? You have to be clear because if its just weight you wish to lighten vs make things beautiful then it will be easy. If its a combination of beauty and weight weenie you seek....o_O
