Paris Roubaix 2011: Team Sky mechanic talks about Bradley Wiggins's Pinarello bike

[joepapp01]

not very enthusiastic...hmmm.

[lilou1003]

luv the way he hides the O'symetric chainrings to not upset shimano lol...

[vinesen1]

wow, i have the same bottle cages!!!!!!

[baralah]

huh????? chain guard on Di2, why??????

[kona6495]

@baralah dont know if you've noticed, but the roubaix is a little bit bumpy in places..

[TheBphelan]

A really fundamental question and concept...I am a big fan of aluminum, and I am looking at purchasing a new stem and handlebars. However, even if I buy aluminum, I am still connecting the aluminum to a carbon fiber tube, on a carbon fiber fork. If that is the case, have a REALLY accomplished that much by sticking with aluminum?

[deathgunner7]

@TheBphelan you will have significant dampening and road vibration absorption compared to a alu connected to a steel steerer tube (that is if your fork is full CF, the forks and the steerer) this is dampening effect is greater than say a steel steerer (or fork) connected to a CF stem and/or handlebar

[zebedee147]

Whoever is saying aluminium bends is a twat.. It fails when it breaks shearing off. I know because I've snapped a set of aluminium bars

[Sebastianaproduct]

@zebedee147 Aluminuim bends - but when it is bent past a certain point it will shear:

Alu 6061T6 (common alu) breaks after ~ 17% elongation

Carbonfibres breaks after around  ~ 0.5%-2% elongation

In engineering terms - aluminum is significantly more elastic than carbonfibre

[hagenar]

@zebedee147 I've snapped aluminium bars too. And steel forks. And carbon ski poles. But I've also bent aluminium bars, rims, and derailleur hangers. Sometimes I wrap sandwiches in aluminium foil. What a twat I must be.

[ran839]

that frame set with every bend /tube shapes / fork angle/rear stays/bb shell/tt/ are just about identical to the avanti cadent

[planbpro]

It doesn't seem like any of the pros are actually running the Dura-Ace 7900 pedals. They all seem to be hanging back with the 7810's as seen here... Is there an issue with the carbon pedals?

[CWake1]

If carbon isn't prone to fatigue like aluminum, then why so many alu components?

[lexel992]

@CWake1 Because it's snapping easier on hits. So if you would crash and hit the ground directly with your bars, you have a bigger chance to snap a carbon bar than an aluminium one - the alu would only bend unlike the carbon which can not be bended.

[CWake1]

@lexel992 Oh... I've seen lots of carbon rims disintegrate in crashes now that you mention it, makes perfect sense, thanks.

[dawall82]

@CWake1 because clearly fatigue is a major concern to a pro cycling team

[CWake1]

@dawall82 Hahaha! it took me a second...

[davidoffon]

Special tyre hand made by a French guy, compliment or insult? Who is he, where z hang out?

[wngdfeet]

drooooool look at all of those pinarellos!

[baroh2413]

Aluminium baby FTW!!! I have two bikes... the carbonbike is like my beautiful wife who I take out to nice restaurants and fancy nightclubs... the aluminium bike is like my lover who i have passionate and wonderfull sex with in cheap motelrooms... (metaphorically speaking that is)

[davidoffon]

Respond to this video... I don't squeak metaphor but I betcha Stannard was fluent yesterday!

[GanjaTaz]

@baroh2413 & if you wanted a dirty woman to bone in an alley and mess up your life you would get a fix wheel right? ;)

[baroh2413]

@GanjaTaz Exactly... but I wouldn't go that far... fixies = White trash

[jpckuijer]

@baroh2413 your wife knows when you've been out with that aluminium slut, because you go into the shower immediately after seeing her.

My everyday bike by the way is really old and heavy, but at least she's always ready for a quick 15 minute ride and other guys don't try to steal her if i leave her unattended.
