WILIER ZERO.7 (SRAM RED E-TAP)
Please also note that the image used is only for illustrative purpose. The actual bike has the following key components:
SRAM Red E-Tap, 52T/36T crankset paired to an 11T/28T cassette.
Scope R4 Carbon Clincher (1,520 grams), 45mm deep, 19mm internal and 26mm external rim width.
The following is a review by Bike Radar's James Huang on the Zero.7:
Now, the bike obviously can't do anything to directly increase your power but lots of stiffness can at least make it seem like you're making the most of what you've got. The Zero.7 ably handles that department as well with a chassis that's admirably stiff, snappy, and stout. Rise up out of the saddle and swing the bars side-to-side and you're met with the torsionally rock-solid front triangle. Likewise, mash the pedals as hard as you can muster and there's no sense of rear-end wag whatsoever.
Regardless of what your actual output is, this thing feels like it was just born to go uphill.
Further helping matters in the uphill department are the low-inertia Mavic Ksyrium SLR wheels and wide-range gearing with plenty of smaller ratios to help maintain an efficiently high cadence.
All this isn't to say that the Zero.7 is a one-trick pony. Once you've crested the top and start accelerating down the other side, you're rewarded with Wilier's usual confidence-inspiring handling that's both stable in a full tuck and carves through corners with aplomb. Just as that chassis stiffness makes the bike feel quicker going up, it also makes for more predictable manners since there's so little chassis flex to interfere with your intended course.
The front end of the wilier zero.7 is impressively solid when you're torquing hard on the bars: There's no noticeable flex upfront when torquing on the bars
Not surprisingly, all this stiffness does come with a penalty. Although the Zero.7 delivers a very nicely damped ride in terms of road buzz and vibration, it's rather rough and choppy any time the road gets legitimately bumpy particularly upfront. Washboarded dirt roads are especially challenging.
On the plus side, there's ample room for more voluminous rubber with about 34mm between the chainstays and slightly more through the fork crown. Seeing as how wider tires have been proven to roll faster anyway, we'd strongly recommend going with at least a 25mm-wide setup.
Frame: maximum structural efficiency, aero be damned.
As is common with carbon road frames that prioritize low weight and high stiffness, the Zero.7 uses nominally round tube shapes throughout, and huge cross-sections in the main triangle a proven formula for producing maximum torsional and bending rigidity with a minimum of material. Saving a few more grams is the straight 1 1/8in steerer tube, which doesn't noticeably detract from the frame stiffness, at least in smaller sizes.
Out back are tall asymmetrical chainstays with integrated, hollow dropouts to keep rear-end wag at bay under hard efforts, slender seat-stays that at least visually promise a smooth ride, and a big, fat BB386EVO press-fit bottom bracket shell.
As is essentially standard fare these days, the derailleur cables and rear brake line are all internally routed and convertible to an electronic drivetrain as needed. To Wilier's credit, it's rather neatly done with smooth housing paths and big exit ports that make it only minimally frustrating to replace the cables.
We didn't suffer any bottom bracket creaking during our testing but given the fit quality of our bike's plastic cups (which were liberally greased but less than confidently snug, shall we say), we'd be surprised if it didn't eventually start to audibly complain later. Wilier does at least line the shell with aluminium sleeves, though, and a set of aluminium bottom bracket cups we tried pressed in much tighter definitely a target for a future upgrade.
We've occasionally found Wilier's published frame weights to be on the optimistic side but in this case, things aren't actually too far off. We measured an actual weight of 849g for a small-sized frame complete with the requisite cable hardware, rear derailleur hanger, seat post collar, and water bottle bolts not far off from the 799g claimed figure, which likely refers to a raw chassis with no additional bits bolted on. The matching all-carbon fork is 307g with a trimmed steerer.
Either way, this sucker is seriously light.
Summing up the Wilier Triestina Zero.7 is simple. Love to climb? This bike is for you. Just be sure you're okay with your wallet getting appreciably lighter, too, because this thing sure isn't cheap, nor is it even remotely good value. It's a fantastic bike but given the price, we expect more than aluminium clincher wheels, an aluminium bar, and a mechanical drive-train.
