Forgive an ignorant question but ....... what are the black bits in this photo?
it's carbon fiber that was bonded to the Adroit frame and forks
Glad we are back on topic
So what was the idea of the CF ... strength, stiffness?
I think i'll add strenght and stiffness, i'll let you know once i drove it...if it make's a difference...
The boron/CF was actually added to dampen high frequency vibrations in the frame which is supposed to improve rider comfort over a long ride. The way the material is applied to the frame wouldn't do much if anything to increase stiffness or rigidity. If you think about it...strike an aluminum tube with a pencil like a musician strikes a triangle and what do you hear? A ringing sound as the metal vibrates and air passes over it. Do the same to a piece of PVC pipe, a carbon fork or pretty much anything made of plastic and what do you hear? Pretty much just the "twack" sound of the initial hit but no subsequent ringing because plastic/carbon fiber/etc. doesn't vibrate like metal does.
Thicker aluminum tubes don't vibrate as much as thinner tubes but they way more, so Klein combined thin aluminum tubes with boron/CF to get a lightweight frame that didn't vibrate as much as it did without boron/CF.
Does reducing vibration improve rider comfort? You'll have to ask the folks that ride an Adroit for the answer to that.
