Carbon Fiber 796/1100 Subframe?

[xplodee]

I agree, in fact it'd have to be about 5x cheaper to be worth it compared to the price of BST wheels, as you'll feel the effect of unsprung weight reductions 5x more than sprung weight reductions. Not to mention the improvement in overall handling due to better suspension functionality with less unsprung weight.

But, regarding the weight of the original aluminum, those subframe bars are beefy and cast. Even a trellis aluminum subframe would save over the stock parts...

those people with money to burn, sure this is great. but if it's about the same price of say BST CF wheels, you'll get more bang for your buck with the wheels.

NOW, if you could afford both...

Ding ding ding!!!! We have a winner!!!!

have you had them off in your hands? not that beefy, but true a trellis AL would be lighter. but remember the suspension point is on the left subframe, so there needs to be a bit of serious strength to that area.

I'm dig'n that red carbon. That's cool - never seen that before. 

[bunnyman666]

It is most likely a red tint added to the clear. That's How I used to make red carbon parts.

i'd be a bit worried about using cf on a subframe like that... would be kinda worried about it cracking under stress after long term use...

i think it looks sick, but the hole in my pocket would make me sicker.

anyways, ill keep posted.

anyone making a trellis version?

It all comes down to the builder and designer. Considering how long people have been riding carbon fibre bicycles, I wouldn't worry; especially since CF bikes take so much more stress than a subframe.

I'm hoping for a price of under $1,000 on the subframe, they weigh 60% + less than the oem aluminum, and they are more than strong enough.

those numbers are encouraging.

one more question. are they based on the 796,1100evo or 696 frame. they are all different.

[ungeheuer]

Tsk Raux.... dont go telling him that  

$1000 .  Way too bloody expensive!    .

Are they? Interesting. In a major way or just the grab handles?? 




Oh and BTW Randy.... thanks for getting those Barracuda turn-signals out to me  .

how is the 796 diff from 1100?

I could see it being 60% lighter if the stock subframe was cast or forged, rather than tubular. It seemed like when I built carbon fibre bicycle frames, they ended up weighing about the same as a steel frame; however, the shapes I made would weigh about 10X as much if made out of steel (if it could be shaped like that). I used CF for it's ability to be made into frankly weird shapes that would weigh upwards of 25 lbs in steel; my frames would weigh 4-5 lbs when made in a swoopy shape. A tubular CF frame I built was less than 3 lbs; a comparable steel frame would weigh between 4 and 5 pounds.

I guess I am thinking still in terms of bicycles rather than motorcycles when it comes construction in aluminium. There simply aren't cast or forged aluminium frames on bicycles; they would be unacceptably heavy.

$1K isn't a bad price if it's 60% lighter and just as stiff as the stock piece.

I haven't seen the evo frame, but not sure where the new rear sets for passengers mount.

the old 696 and 796 are at least different in the rear tip area.

can you explain how? havent noticed
