alu bike and carbon weighing the same why ?

[Jaquesdp]

I know this stupid quastion but i dont know enough to feel better about my purchase lol

 

Specialized epic evo Aliminium    12.7kg

 

So the Alu had XO groupset on

no Cleats

 

 

 

Specialized Epic Expert Carbon   13.5kg

 

GX Eagle , Carbon rims , 

 

Only difference was that the Shimano Cleats was on the Carbon bike already and 2 bottle cages.

My carbon EVO weighed 12.5 at the LBS when I took delivery.

Stock standard XL size, tubes, no computer, one cage no bottle,Time atac pedals

There is a considerable weight difference between XO and GX and then add the weight of a set of pedals. A carbon frame is generally only about 200g lighter than a good quality aluminium frame.

If i work out randomly , same groupset and pedals then Carbon might be 500g or less lighter but can be totally diffrent ride im sure ?

You buy carbon for ride feel, not weight savings when it comes to trail bikes. A carbon trail bike has a burlier carbon lay-up than a carbon XC bike, and that makes it around the same weight as an alu bike.

 

My carbon trail frame actually weighs more than any alu frame I have owned.

 

So the weight diff you are seeing probably comes down more to component spec than anything else. Have a look at the tyres too - that adds quite a bit of weight.

It is a common misconception that carbon is infinitely lighter than Alu...

 

The Trek Emonda ALR (alu) frame was actually lighter than the entry level Emonda S carbon frame by a significant amount...A good quality alu handle bar can be significantly lighter than a "cheap" carbon bar...

 

The benefits of carbon are that in wheels it creates a stiffer rim which handles better, in a frame you can create a unit that incorporates certain handling aspects (better vertical compliance) without sacrificing stiffness...

My Fuji team SL was lighter than some carbon bikes. 

 

Cheap - light - durable.

 

Choose 2. Goes for carbon and alu. 

[Jaquesdp]

I was just surpirsed was thinking about 1kg lighter hehe.

 

Thanks for input i feel better was scared they filled my Carbon frame with sand or water

You buy carbon for ride feel because you want carbon,   not weight savings when it comes to trail bikes. A carbon trail bike has a burlier carbon lay-up than a carbon XC bike, and that makes it around the same weight as an alu bike.

Isn't you wallet ligher though? - That will always make carbon ligher I am sure

[Jaquesdp]

nevermind the wallet , bank account , Girlfriend is pissed , Bank manager up my ass..

 

beter be worth the ride hehe

[Shebeen]

What is the point of comparing the entire bike?

 

 

 

if you want to look at alu vs carbon directly, look at the frame weights. The other 80% of the total weight is just clouding the issue

[Captain Fastbastard Mayhem]

X0 is significantly lighter than GX when you include the cassette in the equation, and pedals are also not light. 

 

Also - primary benefit of carbon is not weight, it's frame stiffness.

..........Also - primary benefit of carbon is not weight, it's frame stiffness. 

.......and there I always thought it was for the bragging rights

Throw the scale away and just ride the bike.
