get KCNC parts !Mattias_HellÃ¶re said:Here´s my prototype, I will try this on my indoor trainer then on a road bike then a MTB.
All my bikes use 27.2 diameter so the tube has a machined UD carbon shim at 7 grams to fit a 25.4mm UD tube.
Supposed to flex and dampen trail irregularities but have to find really lightweight and cheap clamping hardware to the saddle rails.
As it´s a prototype it CAN break.
Shown below are the parts of the 27,2 size
So if i'm calculating right your seatpost would come out at around 107g.That's light! I doubt that the halfround carbon piece will hold up but other than that it looks good.
