Thanks ...

see only kaki no gatal meh?

i like this scene of nwd9

I'm not the one saying.
It's my friend who told me.

carbon is stronger the steel.

unless u use road bike post it should be ok.

only thing with carbon is it should be replace every 5-8 years depend on the epoxy. also you should not adjust ur high frequently as the movement scratch the epoxy layer.

Of course... they should've banned carbon fibre from formula one ages ago man... and go back to aluminum construction.

If stronger than steel then why some people say don't use for DH type of cycling or seat post material??

Are you serious or being sarcastic?
If it (carbon fibre) is stronger than steel, why wanna change to aluminum?

DH need strong n rigid frame with good suspension for max stability. Carbon is strong n flexible.
Some more lighter frame(carbon) is a disadvantages in DH since the build momentum low.

Btw for XC as per pic, you guy follow the previous bike trail or create ur own trail? Cause if follow, the suction create between the "u" mark with tire will stall ur bike but if create new trail u need to "break" the mud. cycle via grass area n u-turn is no permitted

Also follow is also harder in steering n balancing cause the bike steering is held by the mud wall (i cant explain the feel but i think those whom tried know waht i mean).

carbon can be easily made stiff. its all in the construction. GT already has a carbon DH bike. it was created cos they wanted the best stiffness to weight ratio.

anyways, there is no issue with carbon frames being too light for DH. lots of DH competitions involve some pedalling, so less weight=less inertia=better acceleration, and also better cornering due to less centrifugal forces.

another thing, if carbon wasnt stiff, nobody would have used it on roadbikes, since all the pedaling energy would have been wasted

I think of just the business perspective niah since a lot of times... misconceptions are generated to justify something.

We all know carbon moulds are very expensive and are substantial investments.

Even the big guys like Giant will run new models for a year or so to test market before investing in the carbon moulds.

And frankly speaking... while a lot of folks *sigh* watches these "extreme" vids on youtube and aspire to terjun from high cliffs... big travel DH rigs are really niche machines and the volumes alone don't justify the investment especially since most of the "cool" DH/FR specific brands are really teeny companies.

As it becomes trendy to be extreme.. as with the recent development.. can see carbon DH rigs appearing di.

I see, thanks for clarifying.
Regarding picture.
If have momentum should follow previous trail cause don't wanna mess up the area if it's free.
If it's paid for like FRIM, I ride whichever/whatever way I like.
How come you'll lose momentum (bike gets stalled) when ride in previous trail? (Unless it's heavy/thick).
Btw, may I know what's wrong with "breaking" the mud? Is it cause the mud is heavy/thick, so breaking it = Waste energy?

Are you studying engineering?

kid, he is being sarcastic. carbon is strong and lite, but it doesnt mean you need to use it everywhere. and there are carbon dh bikes.

I dream of a carbon fibre kickstand

and fenders

+1

on a side note, McLaren's new P11 car has a carbon fiber chassis.

anyways, some people still have the misconception that AMD rigs overheat. going to lengths to say that nobody should ever buy an AMD laptop or it'll burn ur family jewels

sorry for being off topic, just trying to enforce a point

u should protect the environment..

the mud wall and the tire wall friction will act like "disk brake". this is only applicable it is trail is deep enuf n the tire is wider the trail.

Not mention the steering is "heavy" thus u have lil control on the direction (balancing issue if ride slow, cant avoid obstacle if fast)

u have no really do XC wait till u need cycle through 3 inch of mud (ur shoe also stuck if walk ).. cause breaking mud, u just dont know how deep the mud.

i think u can DIY the kickstand. at least for the kickstand rod. buy small diameter carbon fibre handlebar, cut it to length, then replace a normal kickstand rod with it.

you can saw off golf driver's with carbon shaft too..

ok ok carbon issue closed. now all back to my question..

Okay, I get it now.
Thanks for the fast replies.

What tires are you using?
Kenda Nevegal 2.1s?
Referring to 1st bold phrase: If your riding slow, you should be able to avoid obstacles fast enough.
Referring to 2nd bold phrase: Yes, I have cycled XC at FRIM (many times) and Kiara (once).

or badminton racquets

but use handlebar can get FSA or easton EC90 "branded" kickstand
