Null Winds’ Upper Wheel Fairings Blinds Headwinds with Science

null-winds-upper-wheel-fairings

Null Winds Technology has taken their Upper Wheel Fairings to Kickstarter to bring wind cheating shields to the masses.

Admittedly, they’re not for racers. And they’re different looking. But the science is interesting, so let’s have a look. Inventor Garth Magee says wind speed affecting the top of the wheel is up to 3x the speed of the headwind. That’s because the tire and spokes are all rolling directly into the wind at twice the speed of the bicycle. Of course it’s variable based on head wind speed and bicycle speed, but the power needed to overcome the drag rises in proportion to the cube of the wind speed. So, the faster the wind and the faster you try to go, the more power you’ll have to pump out for smaller and smaller gains.

His Upper Wheel Fairings block the spokes from “fanning” the wind against your efforts. Magee says the result is up to 20% more speed for a given effort…

SOC 14: Fezzari’s Prototypes Lighten up for Road, Add Discs and Thru Axles for Road and CX

Fezzari prototype disc road cross bike (3)

After a strong showing at last year’s SOC in the mountain bike department, Fezzari was back for 2014 with 3 new skinny tire prototypes. Whether you’re looking for standard road, road disc, or disc CX, Fezzari will have an option for you in the near future in line with their consumer direct sales model. That’s not to say the new bikes aren’t impressive looking machines though – Fezzari’s newest bikes look to be just as, if not more up to date with the latest trends as most major manufacturers.

SOC 14: Lapierre Shows off Aircode and Pulsium Road Bikes, Introduced Overvolt MTB

Lapierre Pulsium Aircode Overvolt (4)

After introducing both the Aircode aero road bike and Pulsium endurance road bike earlier this year, we finally got a chance to see both bikes up close and personal. Of course, one of the biggest things we wanted to check out was the elastomer “suspension” on the Pulsium and find out just how it worked.

While the mountain bike line up will see a few changes to their OST and IE platforms for easier use, the big news on the mountain side is the new Overvolt line. Just what are the Overvolt bikes? Well as a hint it has something to do with volt, and nothing to do with my last name…

SOC 14: Xentis Goes Stealth in the US for XBL 4.2 and Squad 4.2 Disc

Xentis Black on black wheels carbon (4)

Decals on rims are always a love ‘em or hate ‘em affair. It’s usually only when those decals or graphics are on $2,000+ wheels that it really becomes an issue. If you’re a fan of the blacked out look or just don’t want to be a rolling billboard for the brand of your next set of wheels, check out Xentis’ new finish. The black stealth finish will not only be offered on the 4.2 XBL and Squad 4.2 disc wheelsets, but it will be the standard color in North America. If you’re a fan of the current white graphics don’t worry – they’ll still be available as an option. Stage Race Distribution had the latest samples on hand which are currently limited to their 42mm wheels, but will be available across the line soon.

Close ups after the break…

SOC 13: Wahoo’s Universal TICKR HR Monitor Shipping, RFLKT iPhone Bike Computer gets a +

Wahoo RFLKT + HR Strap iphone computer

If you’re looking to track your heart rate, but only want to use one strap for all of your devices, Wahoo has you covered. Thanks to the aptly named TICKR, you can connect to either ANT+ or Bluetooth Smart compatible devices (including Trek and Giant integrated computers) all with the same strap. Designed to work with a number of fitness tracking apps like Strava and Endomondo, TICKRs also work great with Wahoo’s own Wahoo Fitness app and the new Burn or Burst training plans that are built into the app. The dual band HR strap has LED lights that let you know it’s working, while the more advanced TICKR Run and TICKR X (coming soon) will have features like speed/distance on a treadmill, built in memory, and more. The standard TICKR is available now for $59.99.

Wahoo is also now shipping the RFLKT+ which has all the same features as the standard RFLKT, but adds an Altimeter. The computer also serves as a connection between your phone and ANT+ sensors, meaning you can use ANT+ devices even if your phone is only equipped with Bluetooth. For those unfamiliar with the RFLKT, it basically reflects the data on your smart phone to the computer screen on your bike. You can control all of the functions directly from the handlebar mounted computer, while leaving your phone tucked away in your jersey pocket or bag. The RFLKT+ retails for $129.99, while the standard RFLKT is still $99.99.

Mavic “Studying” Road Disc Brake Wheels with Felt, Others

Felt Disc cyclocross road f2x f1x f3x nine frd z2 disc (11)

Perhaps you noticed those as-yet-and-still-unannounced Mavic Aksium disc brake wheels on the new Felt F4X cyclocross bike. They’re certainly not a production model and, in fact, may have surprised even a few Mavic folks with their attendance at Sea Otter.

According to Mavic’s PR man Zack Vestal, the brand is testing Aksium Disc wheels with a few bicycle manufacturers to study demand. While we’d say it’s a foregone conclusion they’ll have them eventually, Vestal says “Mavic is working with a few OEM partners to assess the potential of select road or cross disc wheel models. Our product managers are always advancing wheel development in consideration of the needs of cyclists at every level.”

He added that it’s not a surprise to see things start with the Aksium line as it’s a popular OE price point model. We’ve heard Mavic has a few good sized announcements coming this year, so perhaps we’ll see something sooner rather than later.

SOC14: Parlee Cycles Updates Z-Zero with House-Made Tubes, ESX Aero Road Bike Shipping

Parlee-Cycles-Z-Zero-road-bike-in-house-made-carbon-tubes

When we visited Parlee in Massachusetts a while back, they had a single roll press for Bob to play with. Now, they’ve started making their own tubes 100% in house. Before, ENVE was making their round tubes, but now they’ve got a huge new hydraulic heat press and are bladder molding all of their tubes about 20 feet from where the frames are pieced together.

Parlee’s sales/marketing director Tom Rodi says it’s been a three year process, and it means all the tubes are now shaped, no longer just round. That includes the seat- and chain stays. For now, they’re not bladder molding entire sections of the frame as one piece…just making the individual tubes that way. They’re still joint wrapped like before, which gives them full control over the lengths and angles – They are full custom, after all…

SOC 14: Felt Adds More Disc Brakes and Thru Axles to Cross and Road Bikes, Updates Nine FRD Frame

Felt Disc cyclocross road f2x f1x f3x nine frd z2 disc (13)

2015 looks like it will be the year of the disc brake and the thru axle for cross – or at least some combination of the two. Add in SRAM’s CX1 and you have the makings for some exciting cross bikes this season. Felt has taken full advantage of many of those technologies with a full line of competitively equipped CX bikes to get your race on. Bikes like the new F4x which is their complete bike speced with SRAM CX1. The UHC Performance carbon frame uses a BB30 bottom bracket, tapered carbon fork, and a disc brake set up with Mavic’s new Aksium disc wheels. Thanks to the new CX1 optimized cable routing, this might be the most pressure washer friendly bike yet. Find out what that means next…
