Zipp Firecrest wheels get better, stiffer hubs and lower prices for 2016, plus new wider tires & more

2016 Zipp Firestrike 404 aero wheels get new hubs

For 2016, Zipp’s reference wheels get upgraded hubs, the tires get wider and their 30 Course alloy wheelset gets  a rim brake option, adding to the disc brake set introduced in April. Before we dive into the details, here’s a bit of history on the brand (if you’re already a fan, skip ahead two pics).

Zipp was founded by Leigh Sargent, who came from an F1 background. The story goes that a cyclist brought him a disc wheel and he said he could do better. He did, cutting the weight in half by making it out of carbon fiber. Then he pioneered the use of the wind tunnel in cycling, bringing that over from F1, and now they use it extensively at the ARC in Indianapolis. They’ve done things like bike frames (2001, 3001), tri spoke wheels and even carbon cranks. They don’t make those items any more, but they do continue to push carbon development on their wheels, and the latest is their Firecrest rims…


Eurobike Coverage Review – Week #2: Chosen goes for 12 Speeds, Cippollini Gets Aero, DT Swiss & HED Get Wider and MORE!

Welcome back to Eurobike coverage part deux! With more categories to cover than ever, this year’s show was huge and kept us on our toes more than ever. Pour yourself a well deserved scotch, kick your feet up, and travel into this week’s coverage of Eurobike 2015.

And in case you missed Week 1’s exciting coverage, check it out!


EB15: TRP adds flat mount Spyre mechanical disc brakes, new aero rim calipers & updated forks

TRP Spyre Flat Mount mechanical disc brake caliper

TRP’s Spyre mechanical brakes are among the only non-hydraulic calipers on the market that move both pads inward toward the rotor, making them a popular aftermarket add-on and OEM spec piece. Soon, they’ll have a Flat Mount option, too. This one’s a prototype still showing the CNC marks on the body, but production units will be far more polished. Check out the backside and more new brakes, plus an updated carbon fork with more axle options and mounts, below…


EB15: HED gets wider, lighter and cheaper for road, triathlon and fat bikes w/ new hubs, rims & wheels


HED’s booth was chock full o’ new wheels, but you’d have to look closely to find them all. The graphics and overall black on black with more black color theme meant everything maintained their stealthy look. Fortunately, they guided us through it all, and there was a lot to see.

Starting with the more affordable items, the new Ardennes GP disc and rim brake wheels let you get into a HED wheelset for as little as $700 retail by using the same rims as the rest of the line paired with round spokes and their original Sonic hubs rather than the new 545 hubs.

The new hubs, shown below, are available in both disc and rim brake versions for road and cyclocross. They use a new five pawl design to maximize bite and have a chiseled straight pull flange that helps create stiffer wheels. Not shown, the Stingers and Jet Black wheels will be reworked with the new hubs, which makes them stiffer, and other models get the same new internals but with J-bend spoke flanges.

Where things start getting lighter is with their all-new carbon fat bike hubs and complete wheels…


Campagnolo direct mount brakes stop the gap in lineup…for now

Campagnolo direct mount aero road bike brakes

Hot on the heels of decidedly more digital updates like a new EPS battery and wireless transmitter and the MyCampy app, Campagnolo hasn’t forgotten the mechanical parts. They’ve just added direct mount brakes, giving aficionados the same improved stopping power and aerodynamic improvements afforded Shimano and TRP users.

The two-bolt mounting design comes in two iterations, one specifically for forks and seatstay placement (on right), and an alternate rear brake design that provides a better option and more clearance for under-the-bottom bracket chainstay mounts. They use the same Skeleton design as their standard rim brake calipers to keep weight low and stiffness high, and easy adjustability is built in, too…


EB15: Vittoria Reworks the Road with Graphene Corsa and Rubino Updates, Details New MTB Tires


Vittoria’s road tire line gets a major Graphene addition and an overhaul with the Corsa family now covering all of the race tires and the Rubino name encompassing the all-purpose tires. The Graphene that they added this year to their rims, goes into the tires now for a mixture of grip and durability, in what they call an intelligent tire. We’re pretty curious to see how much the science backs up the supposed magic material that we’ve also seen reinforcing Catlike helmets as well, so we’ve got a feature in the works for later in the year to go visit the engineers who design and build with this stuff. Stay tuned for that.

In the meantime Vittoria’s road shuffle has some interesting implications, and a bunch of new tread designs and casings. Plus, the mountain bike tires that we saw in Tapei and the prototypes from Sea Otter have materialized, and we’ve got the details. And there is even an interesting urban tire that promises lower rolling resistance than the competition, with good cornering abilities. Read all about it after the jump…


EB15: Absoluteblack brings 1x, 2x, oval and aero chainrings for road, cyclocross & MTB


The folks at Absolute Black are expanding their oval chainring offerings to include road-ready ovals for 2x drivetrains, aero chainrings for fast single ring setups and more narrow/wide oval options for cyclocross. They’ve also expanded the mountain bike offerings to include Shimano bolt patterns.

The most eye catching product, though, was the aero chainring, which offers an oval shape for 1x applications and a unique spiral groove pattern to brush the air off…


EB15: Rotor Uno hydraulic road group – first look & tech details!

Rotor Uno hydraulic shifting road bike group tech details and photos

Our discovery of Rotor’s hydraulic shifting patents turned out to be well timed, teeing up the group’s public debut nicely. Turns out, our technical breakdown of the groups functioning was nearly spot on, so we’ll recap:

By using a completely hydraulic system from the shift lever all the way to the derailleurs and putting the ratcheting mechanism on the derailleurs, Rotor was able to eliminate any slack from the line that could lead to loose shifting. The side benefits of such a system included lighter weight and plenty of functional improvements that simply can’t happen on a cable-driven or mechanical system.

The key to the system is precision and reliability. Hydraulics have been proven in everything from bicycles to airplanes to heavy industry, just not for bicycle shifting until now. Their motivation was to let customers looking at Rotor’s oval rings and lightweight alloy cranksets find an entire group with the same brand. Undoubtedly, it will also give them more opportunities to put the group on pro teams that may otherwise have to opt for SRAM, Shimano or Campagnolo groups simply because of sponsorship programs dictating complete group use. And they hinted we might see some major teams on the group very soon. But that can’t be enough to justify the heavy time, energy and financial commitment the development of such a product can draw from a company. So, it needs create demand based on its merits. Of which, there are quite a few.

Check out the cutaway photos and tech details below, along with new carbon chainrings, and new 1x rings for road and mountain…


EB15: Stages adds power meters to carbon cranks – Campy, FSA & proprietary SRAM solutions


Stages Power has finally unlocked a way to bring their single sided power meter to left crank arms everywhere. Or, at least, to modern Campy, FSA and most SRAM cranksets.

To make it work with carbon,they had to develop a new strain gauge and assembly method – it takes about 30% longer to install them on carbon then on the alloy arms. They have to polish off the top clear coat layers, but don’t worry, Stages assumes the warranty from the original manufacturer should anything happen. The actual physical changes to the strain gauge and other internals are not something they would divulge. But they did say that one of the biggest challenges was keeping it accurate in fluctuating temperatures. Once they solved that, they were able to offer a product that doesn’t need to be zero calibrated when the temps change, maintaining its accuracy from ride to ride.
