Knight Composites takes shadowy flight into drag-fighting aero carbon wheels

Knight Composites 65mm deep aero road bike wheels

If you’re looking for the fastest aero wheels in the world, keep your scanners peeled for pro triathlete Heather Jackson aboard her new Knight Composites carbon fiber hoops this year.

Who’s Knight Composites? Oh, only the new brand intent on making the fastest bicycle wheels ever. Considering the massive interest in improved aerodynamics leading the development cycle at major brands like Mavic, Reynolds and ENVE (among many, many more), that’s a tall order.

So, they began by looking at the wheel as part of the whole bike because, well, you can’t have one without the other. Their testing revealed that the trailing edge had a more profound impact on overall aerodynamics than the leading edge…and by “trailing edge”, they’re mainly talking about the back half of the front wheel. So, they developed what they call Trailing Edge Aerodynamic Manipulation (TEAM) Tech.

But first, they had to assemble their team…

Why Isn’t Road Tubeless More Popular? Part One – How We Got Here

Bontrager RXL TLR Wheels Road tubeless (6)

Road Tubeless is an interesting topic, because it came on the scene very fast in 2010, and many thought it would become the next big advance in road bikes through 2011 and 2012.  However, as we venture into model year 2015, it still has not taken off in a significant way, with modest or underwhelming offerings from a handful of suppliers that may or may not work together.

So, what’s the hold up?

Well, to put the whole situation into perspective, we need to look at the evolution of mountain bike tubeless tires.

Lets step back to 1999, when the first standardized mountain bike tubeless system, UST, was launched by Mavic. Established over 16 years ago yet really only becoming popular in the last half decade, mountain bike tubeless also took a while to catch on, even though there are arguably a lot more benefits to tubeless tires off road than on. But, despite nearly universal agreement that mountain bikes perform better with tubeless tires, there is still not an agreement what the interface between tire and rim should look like…

Found: Crank Tip Promises Less Fatigue & Greater Power w/ Unique Dual Swingarm Pedals

cranktip-racing-pedal-hero-3

Free power and less fatigue. That’s every roadie and triathlete’s dream, right? As far back as 1898, inventors have been looking toward the design of the pedal as a means of improving performance on the bike. Looking quite a bit more advanced than that first Ramsey Swinging pedal, the Crank Tip Racing Pedal promises reduced fatigue and increased power all with a simple change of your pedals.

Utilizing a dual swingarm design, the pedal is able to float laterally during rotation. It’s this back and forth movement that Crank Tip claims is responsible for a biomechanical advantage capable of reducing a rider’s heart rate by “5-10 beats.” Slide into the details next…

Are You Oval Ring Curious? Rotor Is Now Offering A 30 Day Trial With TryQ

rotor-power-lt-r-driveside-single-side-powermeter-crankset

Rotor has been building their business on the performance benefits of oval-shaped chainrings, that are said to get rid of the dead parts of a pedal stroke. However, selling oval chainrings in the bike industry can be the butt of many jokes, after the unfortunate life of Shimano’s BioPace rings. These jokes can make people skeptical, and not willing to give the idea a try.

Rotor is launching the TryQ program only through shops so they can adjust each customer’s Optimum Chainring Position to the precise point when the rider delivers the maximum power during a single pedal rotation. The program exists so that at the end of 30 days, if the customer decides to return the Q-Rings, he or she is entitled to a full refund. Check out all the details after the jump…

Garmin Goes Big into Wearables, New Vivoactive Smartwatch, Fenix GPS Watch, Epix GPS Mapping Watch, more

garmin vivo wearable connect watch (4)

Television and films over the years have had some lofty expectations to what the future of tech would hold. From flying cars, to clothes made out of metal, most of the entertainment industry’s prophecy has failed to materialize. However, when it comes to your wrist – we are entering the realm of Dick Tracy and his two -way wrist radio.

I’m talking about the smart watch, of course. A gadget that couldn’t have existed without the rise of the smart phone. You may still be on the fence about wrist mounted technology, but thanks to Garmin there are a number of new options to consider. Starting with the new vívoactive, Garmin has a new touch screen smart watch that will appeal to a wide group of active individuals. Along with the vívoactive, Garmin has also introduced the new Fēnix 3 multisport GPS watch, epix rugged GPS mapping watch, and the new vívofit 2.

Whatever your activity or your style, Garmin has some very interesting options to wear your heart rate on your wrist, among other things…

Review: Look Keo Blade 2 road bike pedals provide the snap, clickle & pop!

Look Keo Blade 2 CR road bike pedal review and actual weights

A quick bit about me. For many, many years, I was a Speedplay-only kinda guy. Coming from a mountain bike background, the quick and easy engagement of their Zero pedals just made a heck of a lotta sense. Just stomp and go, and beat everyone else off the line that’s trying to get the entry angle just right for their SPD style pedals.

Then I got a set of Shimano’s as part of the Ultregra Di2 group. Then the Keywins. Then I started really liking the broader platform those offered, even if it did take me a couple seconds more to get clipped in. The latest pedals that continue to sway me are the Look Keo Blade 2, and they provide the most satisfying click of any road pedal I’ve used. And they’re darn light and roll smooth.

We got off to a bit of a squeaky start, but the pedals and I have come love one another…

Eurobike Awards 2014: Road, Tri, Mountain, City, and of course, E-Bikes

eurobike awards bike (10)

If there was one bike in the awards area at the show that epitomizes the idea of a design award, it would probably be the Rafael r-023 Ueberbike. From the driveside it may be easy to overlook if you’re not into tri bikes, but as soon as you take a glance at the non-drive side of the bike it stops you in your tracks…

EB14: Roundup – Road & Cyclocross Bikes to Amaze & Amuse

CKT-by-Virenque-carbon-aero-road-bike01

CKT by Virenque offers frames and branded cockpit parts to assemble a frameset, with a range of road bike models to suit most tastes. The 589 was the real eyecatcher, with a monocoque frame, integrated seatmast and integrated TRP mini V-brakes. The color matched wheels and spokes didn’t hurt it visually, either.

If this one looks fast, there are plenty more below that look even faster…

The Velocite RT50 Aero Wheels May Be The Most Extraordinary Use Of Computer Design In Cycling

Velocite-RT50-2nd-gen-front_r3qVelocite is constantly pushing the envelope of design, releasing the 2nd generation of the RT50 wheel set. Aimed at being aero, but not just in a straight line, the design story on these is long and technical, with Velocite breaking out computer hardware and software not typically used in the cycling industry.

They say the main objective in this redesign was to fine tune the handling of deep profile rims in crosswinds. The methods employed were cool to see, click through to get the scoop…
