Complete Redesign of Wilier Zero.7 Results in Sub 800g Frame

Complete Redesign of Wilier Zero.7 Results in Sub 800g Frame

In the never ending quest of lighter, better, stiffer, stronger, Wilier Triestina has a new flagship. The Zero.7 already held the top spot, but the Italian manufacturer has completely redesigned the bike to remain at the top of ultra modern race machines. That means new cable routing, improved carbon fiber techniques, better aerodynamics, all with the ride quality Wilier is known for.

Zero in on the improvements next…

One of the biggest stories with the new Zero.7 is in the carbon itself. Utilizing a new molding procedure, Wilier has managed to reduce the overall volume of the tubeset without decreasing stiffness or performance. The new method uses a special thermoplastic insert that is placed between the inside of the carbon and bladder. Thanks to the insert, Wilier has much more control over the pressure and inside surfaces of the frame as well as the thickness of the walls which results in a frame with weights under 800g (750g for size M). After the frame is formed, the bladders and thermoplastic inserts are removed.

Wilier also continues with the use of their SEI, or Special Elastic Infiltrated Film. Used in place of some lower modulus fibers in the frame’s construction, SEI Film is a special viscoelastic material that deadens road vibration and results in a stronger frame. Because of the film, Wilier can use up to 60 Ton high modulus carbon while maintaining a comfortable ride. As for numbers, Wilier says SEI Film frames are 35% more shock resistant, 18% less likely to delaminate, and 12% more flexible.

Other improvements to the frame include the introduction of an integrated fork and aerodynamic head tube. Borrowing from the Cento1 SR, Wilier shaped the front end of the Zero.7 to be more aerodynamic without affecting stack height or head tube length. Further aero enhancements have been made using development from the Twin Blade TT bike.

The Zero.7 will be rocking at BB386 EVO bottom bracket which allows for BB386 cranks along with most other standard cranksets. The wider spaced shell offers more real estate for the chainstay/DT/ST junction as well as making more room internally for the new cable system. Wilier is also introducing a new derailleur hanger system they call the 3D Hanger. Along with increased stiffness the hangers are carefully designed for both mechanical and electronic drivetrains for optimal cable/wire placement.

New cable routing is also found through the rest of the frame. Careful attention was paid to making it function for both mechanical and electronic drivetrains while delivering an aerodynamic, rattle free, and easy to service option for either. Large removable ports make accessing the internal bits easy, and any mechanical stops have smooth plugs for running electronic. When running Di2 or EPS, the wires route into the frame through the rear brake port which is locate on the top tube, just behind the head tube.

The 2015 Wilier Zero.7 will be sold in multiple colors and will arrive at retailers this fall. Expect price tags to read $4999 for framesets which include the frame, fork, seatpost, seat clamp, and headset, as well as complete bikes with Shimano Dura Ace or Campagnolo Super Record for $9499 or $10,499 respectively.

Another bike the pros will have to add weight to start races with.

Joe - 06/27/14 - 10:08pm

@ Fisho …. first world “pro” problems

Eric Hancock - 06/27/14 - 10:48pm

The geometry on these frames is really long. I (sadly) couldn’t comfortably ride a frame with that much reach.

Ajax - 06/27/14 - 11:14pm

Who cares? Does it have a threaded BB? No? Okay, I’m not getting it then.

TT - 06/28/14 - 4:01am

I couldn’t agree more Ajax!

MarkV - 06/28/14 - 6:03am

Sweet new ride! That bike looks like a climbing machine. Nice job Wilier!

wako29 - 06/28/14 - 8:48am

Um, 800g isn’t that light anymore. Lighter than most like the Tarmac? Sure. But there are MUCH better bikes out there that are lighter, if that’s your goal.
@Fisho: Good thing you and I don’t race pro
@Ajax: Threaded BBs are going away because of stiffer, lighter, innovative designs. Luckily, you’ll always have heavy and flexy Surly bikes if that’s your thing. I don’t think that Willier cares about your shortsightedness (tip: you’re missing out)

COrider - 06/28/14 - 9:15am

As an engineer, it always makes me laugh hearing all the marketing shenanigans.

Mitch - 06/28/14 - 9:29am

Ajax: Get used to it. I said the same thing and ended up with a PF30 bike. Threaded bb’s on carbon bikes are going away, and it sucks, but it’s reality.

Eyal - 06/28/14 - 9:35am

Why bike co. can’t get their s** together: Don’t send out press releases without updating your website. Nothing on their site about this bike!

Sardus Pater - 06/28/14 - 9:39am

I gave up this quest for the lowest possible weight many grams ago. Set me up at 7kg with pedals and I’ll be ok. I don’t need to feel like I’m riding on a pencil when flying down at 80km per hour….

William - 06/28/14 - 9:43am

wako29. I’m sure you’ll love your PressFit 5000 dollar frame when your BB starts creaking and popping like a 77 AMC gremlin. On a similar note, the owner of my LBS was mentioning that Specialized released a TSB recomending that the BB’s on some of their S-works frames be epoxied in place to prevent creaking. He wasn’t too happy with that. Long live the threaded bottom bracket

Casey F. Ryback - 06/29/14 - 9:17am

Sweet! ANOTHER derailleur hanger design to NEVER have in the shop!

Jeb - 06/29/14 - 2:23pm

For those that think threaded bottom brackets are going away guess again. Felt just announced all their carbon bikes will be threaded bottom brackets next year. Santa Cruz never went press-fit. Praxis and Enduro are selling the crap out of their external bearing converters. And if forums are to be believed consumers are flat out sick of press-fit and will be voting with their wallets. Last two frames I purchased were threaded just for that reason. I really wanted a certain road frame but it came with a BB386 that required a clusterf#ck adapter to run my Shimano/stages power meter so I looked elsewhere.

Tim - 06/30/14 - 5:31am

@wako29- Press-fit bottom brackets are neither new nor innovative. They were tried in the late 80′s-early 90′s on a few brands (Klein, Fat City), and disappeared for awhile. I’ve also seen them on much older bikes; they tend to go in and out of vogue in cycles, it seems.
And just because something is new and innovative doesn’t mean it’s good. That’s not an anti-tech broadside rejecting disc brakes, suspension, bigger wheels, and 1x drivetrains, it’s a simple statement that not every new standard or product should be subject to the same testing as everything else. If it’s old and sucks- chuck it. If it’s new and sucks- chuck it. And by too many accounts, press-fit sucks.

bikermark - 06/30/14 - 8:27am

@eyal: Why? Because their dealers and distributors still have 2014 models left in inventory. You want people to buy what you’ve got right now, not wait for next year’s model.

bikergreg - 07/01/14 - 5:27am

I’ve been riding my pressfit Klein Adroit since 1993 daily, I have not adjusted, greased, lubed or done anything to the bottom bracket. Sounds crazy but it is working, sounding, and spinning like it always has. when things are done right and adjusted right from the beginning the quality parts keep on going. Lets not forget that I have an integrated headset on that bike, 1.5″ I think, that was way ahead of the curve, yes still riding that as well, I have never had to adjust it either. Long live Gary Klein.
