norbar = fail.

I'm not an anti carbon internet superhero you bellend.

I'm an anti carbon DH handlebar Formula 1 Composites R&D Engineer.

All carbon bars will always seem fine, no probs.... until they fail. Suddenly. Without warning.
Yeah because 7075 alu bars will bend before they break ;) ? (protip. trick question). It's no that much differance.
Sorry for going a bit ranty at you but with that attitude of yours you kinda ask for it ;)


Again - what do you have against flat bars?

Geez, Gridds, it's a Taipei Cycle thread, not carbon-handlebar-pure-evil topic. Add something interesting... not just bla, bla, bla...
I've been using FSA Gravity Light Carbon 710 h-bar for two years - no issues.
I've just ordered Easton Havoc Carbon DH 750mm bar. Taking info consideration fact, that Monkey Lite DH CF h-bar is very good product, I don't expect any problems with Havoc.
I have also ordered mentioned new FSA flat CF h-bar. Gonna get it during Eurobike.
I DO believe manufacturers don't want us, customers, dead, so they pay extra attention on such products, as CF h-bar.

Back to the topic...
Is this THE new Maxxis tire?

bastard child of a minion and a high roller?
wow, that's really interesting. more of a cross between the DHR-R and HR rather than a DHF and and HR. Really open knobs, it would seem they would shed mud and brake well. but how would they do on slick rocks and roots? what would they be improving on over which tire? these are genuine questions, not rambling comments!

They are a completely different components designed to do completely different things. F1 suspension does not have a load of sharp edged components bolted to it at varying degrees of monkey tightened torques and then loaded in bending with dirt and grit and crash scrapes all over them. F1 suspension is designed to handle the loads it sees very specifically. It is only loaded at the ends through carefully designed bonded joints.

I'm sure there will be plenty of people who will say "i've been using carbon bars for ages with no issue..." Of course, you won't get an issue or any warning of an issue until one day, JRA, and then BANG. Ooops...


Seriously. I study the failure of carbon composites for a living (in F1 thankyou very much)! I will NEVER run a carbon bar for DH riding.

A handle bar is a very specific component whose conditions of use (and abuse) are in no way ideal for the vulnerabilities of this material. It's almost like, 'What's the worst way to load a light weight carbon tubular beam?' - just bolt some square edged metal parts to it, get some tiny bits of dirt under there, a few scratches and then repeatedly load it (and sometimes hucking overload it) at the ends whilst being supported in the middle by another big metal square edged clamp. See what happens....
I have had carbon bars before, but never again. I am not sayinng dont do it. But FFS stick to reputable companies and replace them every year and clean them like they are some sort of highly sensetive electronic device. One bit of grit under that clamp and things could go bad quick.

As for carbon wrapped on aluminium? Crazy? Spose it could double as a battery for your led head light if done right? Or even temperature sensitive bar rise? Why not titanium? Or just plain carbon???:think:

Sorry, Back on topic...

INTERESTING... very interesting...

I was talking with Ken about this very tire in the pits at the Windham WC last year... Slugger had some interesting thoughts about the characteristics of the DHF vs. the High Roller...

Looks very cool.

If they've released the name, let me know, if not - I know nothing. :D

I've got a bit more info, but they weren't to forthcoming quite yet. Expect more information soon.

Im over here now
It may be alignment tool?
hmm good guess
it looks like it could line up with the park tool headset press. but unless those screws screw into something, youd still be in the same boat of trying to get it aligned. plus the angle is already built into this cup of theirs

my 2 guesses:

1) hydraulic gyro, but i see no ports

2) some sort of angle cup. a terrible looking one at that

Jesus, I'm going to have to start waiting to upload photos until I get my words in order. Bunch of super sleuths over here... Its late here in Taipei and I'm tired as hell, but a rambling story on this beauty will be live within an hour or so.

Flat bar = fail
Carbon handlebars for DH = FAIL! And I don't want get into an argument about why, they just are. Handlebars are the very very very last component on a DH bike that should be carbon. Actually scratch that, handlebars on a DH bike should never be carbon. No matter what the marketing bull**** says.

Unless you don't actually like your teeth/face/life of course, in which case by all means go ahead.
I've been using Gravity Carbon DH bars on my DH bike for 5 or 6 years now. No problems, but I replaced them last year with a fresh pair for safety's sake after noticing a crack in the clear coat. Why are you so completely sure of your opinion without having done careful structural analysis of every carbon DH bar?

And the wonderful Bionicon.

No thanks.

Although I'm sure that Scott and C'dale are very capable bikes.
I always giggle when I see biocons. I wonder who came up with the idea to make a DC enduro fork but forgot to use a 20mm axle instead of a 9mm.
