Zipp_404-Firecrest-Carbon-Clincher-Disc-brake_disc-brake-aero-wheelset_cross-ready

Back in the beginning of the spring Zipp introduced a pair of new aerodynamic wheelsets to suit the needs of the growing number of aero road bikes coming to market. There might have been speculation at the time of really what kind of bike would pair something like their deepest aero 808 rim to disc brakes, but we’ve since seen a number of suitable aero bikes make their debut. Here at Bikerumor though, our thoughts then were mostly to a wheelset that could handle more everyday type riding, so we got our hands on a set of the mid depth 404s to see how they rolled. While Zipp has proven their aero carbon tubulars on the cobbled classics and, in their disc brake guise, on the cyclocross circuit, we wanted to see how the slightly deeper 404 in a carbon clincher could handle both, making it easy to switch tires (and axles) to suit multiple disciplines….

Spy Shots: upcoming DT Swiss PR1400 OXiC Dicut lightweight alloy road wheels

DT-Swiss_PR1400-OXiC-Dicut_light-aluminum-alloy-road-wheels_rim

DT-Swiss_PR1400-OXiC-Dicut_light-aluminum-alloy-road-wheels_overall

We happened to be riding in the Alps a couple of weeks back and spotted a set of new aluminum wheels being tested in the real world by a rider from DT. While DT Swiss has completely revamped their mountain bike wheel line-up this year with the new Spline One range, we didn’t expect to see too much new on the road side of things. That said they are clearly working on some new tech, not just for the advent of disc brakes and the ever-expanding carbon wheel market. What we first noted on these wheels was the lack of the visible brake track. That got us asking questions, and we came away with some interesting info about the new OXiC coating that offers improved braking and durability. Take a closer look after the break…

Tech Talk: Are your bike tires too wide for your rims? Here’s how to get it right

how-to-choose-the-right-tire-and-rim-width

how to match the right tire width to rim width for road gravel mountain and cyclocross bikes

With the explosion of Boost, Plus bikes, Mid Fat and other portly new rim and tire sizes for everything from road to cyclocross to gravel to mountain bikes, it’s a wonder there isn’t more confusion as to what will actually work together.

And by “work together”, we don’t just mean whether or not it’ll mount. We wanted to know what the compatibility limitations are for optimum performance and, more importantly, safety. If we’ve learned one thing from Mavic’s presentations over the years, it’s that tire and rim sizes really and truly are designed to work in tandem. Step outside the guidelines and you risk poor performance, component damage, or even a total blowout. And it’s not just Mavic. We spoke with WTB, Kenda, Schwalbe, Stan’s NoTubes and Industry Nine to see where everyone sits on the matter. Here’s what they had to say…

Stevens reshapes lighter, stiffer & cheaper Comet, Comet Disc & Xeon and more road bikes…

Stevens_Comet-2-0_lightweight-carbon-road-bike_complete

Earlier in the week we took a look at some big carbon updates to Stevens’ mountain bikes coming next season. And while the changes we’ve been shown on the road seem to be relatively minor, it is interesting to see that with each of these 3 updated frame lines, the frames get lighter and their prices go down at the same time. That’s not a trend we often see. Take a closer look as we check out the second generation lightweight Comet, a peek at its upcoming disc brake sibling, a redesign of the more affordable Xenon, and some updates to the Arcalis/Arcalis Disc frames…

Review: Clement LCV clincher road tires offer long term performance

ClementLCVReview2016-1

ClementLCVReview2016-1

Clement tires opened its doors for business way back in the 19th century, circa 1878. Founded by Gustave Adophe Clément-Bayard, the company first manufactured high quality bicycles before moving onto the production of tires some ten years later. The company would later expand into the manufacture and development of aircraft, automobiles, motorcycles and dirigibles – quite a diverse portfolio!

Since those early days, the company has changed owners and moved the location of its tire factory several times. The brand enjoyed much fame under the wheels of racers like Eddy Merckx and Jacques Antequil, but a dormant period during the late 1990’s and into the 2,000’s saw the company completely out of the bicycle business. Like a phoenix rising, the company is back under the direction of Denver-based Donnelly Sports, who license the Clement trademark from Pirelli Tyres. One of the company’s entries into the road racing market is the LCV, a lightweight clincher tire that boasts weights as low as 180 grams for a 700c x 23mm model. Click on through to see how the LCV did during our review period…

Review: AbsoluteBlack Premium oval road bike chainrings

AbsoluteBlack Winter oval road bike chainring long term review

AbsoluteBlack has been making intricately machined oval chainrings for some time, and they’re beautiful. They’re also expensive, so this past spring, they came out with the Winter set for road. Winter being another way of saying “off season”, or “training” rings since they’re a bit heavier and lose the machining on the outer face of the large chainring. That makes them more affordable, but they don’t have the chiseled look of their Premium Oval chainrings, tested here.

The shaping isn’t just cosmetic or to save weight, it also boosts strength and stiffness, aided by their 5mm thickness. Which works, these are incredibly stiff. They also happen to shift smoothly and quickly, and even with a moderate ovalization, slot into modern drivetrains with minimal or no issues…

Werking debuts new custom granfondo road Model S, and teases disc brake prototype

Werking-cycles_Model-S_custom-carbon-road-bike_frameset

Werking-cycles_Model-S_custom-carbon-road-bike_complete

At the end of last year we saw Werking Cycles’ first custom carbon road bike – the Model A – which was built as a light and stiff racer. Now they have come back with a new bike that was in final development then, but is now available. The new Model S uses more shaped tubing profiles than their previous bike to build in more rider comfort. While the new frame adds only about 10g over the racier bike, the Model S is targeted at longer Gran Fondo-style riding and mixes a stiff drivetrain with a bit of seatstay flex for those long days in the saddle. Plus with the addition of a new replaceable dropout setup, Werking is said to be able to offer both rim brake or disc brake specific frames…

Crono’s made-in-Italy shoe line-up is getting an overhaul for 2017, and topping it off is an all-new road shoe with a unique cable layout. Developed in a partnership with BOA, the new CR1 claims to deliver an improved fit for better power transfer. In addition to the CR1 with its new Multi Contact Boa closure setup promising the end of heel lift, Crono renames their entire lineup with a new letter + number system that makes it easier to find where each shoe fits in the overall scheme of things. Along the way the company’s current top-level road and mountain shoes both get a noticeable update, with newly redesigned uppers and a move to Boa closures as well. Take a closer look at the new goodies after the jump…

Van Dessel lets you ride all over the place with new A.D.D. gravelcrossventure bike

van-dessel-ADD-gravel-cyclocross-bike-2017-c

Can’t make up your mind? Wanna ride over here and over there and down this road and that? Having a hard time focusing on just one type of ride? Van Dessel has your Adderall in the form of a bike with their new A.D.D.

Designed to work for cyclocross, gravel or any old adventure style riding, the bike comes with either a carbon race fork or a steel adventure fork, the latter equipped with a wide array of mounts. Take your pic, either one works well on the 7005 aluminum frame with clearance for up to 700×40 road/’cross/gravel tires or 27.5×2.1 mountain bike knobbies. Both forks and the frame come standard with thru axles, but can be converted to work with traditional QR skewers, too…
