Pina carbon : 60HM1K ver 45HM4K

[Tromp]

Pinarello Dogma carbon is 60HM1k. On the Pina MTB , the carbon is 45HM4K. What is the diff. in layman's terms ?

Different grades of carbon fibre used.

 

 

Doesn't mean one is weaker than the other. All to do with the weaving process etc. The 1K in the 60HM1k means its a fine weave

the 4k in the 45HM4k is a bit coarser weave

To the untrained eye you wont notice a difference with the 1st glance but look carefully and you will se a difference.

Like the 60 means more "strands" and one layer and the 45 are thicker but less strands and 4 layers and stronger ? Oops sorry , your first reply did not open up completely the first time ! Edited April 1, 2014 by Tromp

Something like that. As I said in my previous post it doesn't mean the one is weaker or stronger than the other. Bear in mind what makes the frame strong is the lay up of the carbon and what plays a integral role in the strength is also the resin used and how much. Too little resin and the fibres will just be fibre and too much resin the different sheets wont be able to bond to each other. Building a frame they don't just use one specific weave of carbon. A frame is made up of a whole array of different weaves and in some areas there is way more than in others.
