Zipp Releases New Vuka Aero Time Trial/Triathlon Cockpit

Zippity do-dah, Zippity yay- My oh my, what a wonderful day for triathletes and time trial riders! Zipp has just announced the release of the Vuka Aero cockpit, an updated and improved version of the race proven Vuka Stealth.

The new Vuka Aero has been redesigned for further aerodynamic efficiency versus the Stealth model. Some features from other Zipp products carry over into the Vuka Aero, but it also boasts some new ideas and a design of its own.

This integrated cockpit does not include a stem but rather was designed to accommodate different stems for greater compatibility, and so riders can fine tune the fit of their bike without compromising aerodynamics…

Bontrager postures for better saddle fit, performance w/ new InForm BioDynamic designs


Built around five postures and three contours, the new Bontrager InForm BioDynamic saddle collection has something for everyone, from the upright cruiser rider to the horizontal professional TT racer.

Using leisure, fitness, performance, aggressive and aerodynamic postures as the different baselines for pelvic rotation, they then looked at the saddle’s curvature, profile and transition to make them as comfortable as possible while also maximizing performance on saddles aimed at more serious athletes (upright comfort riders aren’t really seeking better Strava times, after all).

As they describe it: “The curvature of the saddle is thought of as a cross-sectional view through the saddle at the critical point of the saddle where the rider is primarily seated. The profile contour is defined by the saddle’s shape in side view. The transition contour is defined by the edges of the saddle in the top view.”

Here’s how all that comes together in the performance-oriented Affinity, Montrose and Anja saddles…


Tri Rig Releases New Completely Redesigned X Series Component Line

Tri Rig has recently announced a new component line under the X-Series name that includes a brake, handlebar and stem. While some of these components are updates on existing models, all of the new X-series parts were completely redesigned from the ground up to gain incremental performance improvements.

Tri Rig has put some serious focus on producing the most aerodynamic parts possible, and they make some big claims about the Alpha X handlebar’s wind tunnel performance in particular. Click past the break to get the skinny on the wind-cutting Alpha X handlebar, Omega X brake and Sigma X stem…

Zipp Introduces Limited Firestrike 404 Tubular Wheels, Updates Clinchers


Last year, Zipp introduced the latest in a long history of aero wheel designs with their new Firestrike platform. Starting with the 404 clincher, the Firestrike moniker became the calling card of Zipp’s highest end wheels. By using a new rim shape and ABLC (aerodynamic boundary layer control) dimple pattern, the new design maximized the amount of stability the wheels provided essentially allowing you to use deeper rims than the conditions would normally allow. Other improvements included their new Showstopper Silicon Carbide (SiC) brake track for drastically improved wet weather braking as well as new hubs, printed graphics, and a new molding process.

There was only one drawback. The Firestrike 404 wheels have only been available in clincher – until now. Not only are the Firestrikes now available in tubular form, but the Firestrike 404 clinchers receive a few updates as well…


Ventum Racing ditches the downtube to get ultra aero

If you’re a tri geek, it’s likely you’ve seen a few shots of the upcoming Ventum Racing bike sneaking around the interwebs. If not, its completely un-UCI legal frame shows just how far things can go when you’ve got no limitations on frame design.

Called the Ventum One, it’s the first bike from upstart Ventum Racing, a brand co-developed by professional triathlete Jimmy Seears. Here’s the story:

“I race professionally, but I got dropped by my bike sponsor,” Seears told us. “My dad and I had always tinkered with and built things, so we thought we’d build a bike. How hard could it be, right?

“We started messing with different designs, and we really liked the Lotus 110 from the mid ’90s, so we started with that. We built the first prototype in Australia in house, which we tested with strain gauges and on the road. Then we tested the second version in the wind tunnel and it was a lot faster than we expected. And that was with a rather messy home made build…the handlebars were pretty messy and jumbled together. So we continued refining the design, and will continue to into the future. So the one you see here now is close, but not quite the final version that’ll ship later this year.”


Extend your Quiet Time With New Zipp Valve Extenders by Silca

zipp valve extender silca 303 808 wheels

There’s nothing quite like the sound of a perfectly tuned bike, especially if it’s fitted with deep dish aero wheels. That whoosh-whoosh is somehow so satisfying. But if you’re running the wrong valve extender or haven’t used electrical tape or some other fix, it can easily be ruing by the constant clicking from your wheels. It’s not surprising that Silca’s valve extenders were a hit as they use an integrated elastomer ring to eliminate the rattle.

Rather than trying to engineer a competing product, Zipp decided to partner directly with Silca to offer some quiet valve extenders of their own. Offered in four different lengths, these are the perfect accessory for your Zipp 303-808s…


Scicon AeroComfort 2.0 TSA Soft-sided Bike Travel Bag – First Impressions


Looking at our spring and summer that will have us stuffing bikes on trains and airplanes to get out and ride in some new places and return to some old favorites, we thought to give another thought to how our bikes would happily and safely make the trip. Whether it was our road and cross bikes that usually traveled by air, or the occasional trip to rail some far off mountain bike trails, we needed something up to the task of protecting just about any of our bikes. Taking a cue from the pros, we’ve started to test the newest AeroComfort 2.0 TSA bag, with its soft-side construction and built-in wheel bags, and are curious to see how it will stand up over time. Our experience so far hasn’t been without a little hiccup, as there are definitely pluses and minuses to a soft case, but our bikes have made it safely to their destinations.


Having refined the AeroComfort for more than 30 years, Scicon has established itself as an industry leader and has earned the trust of the professionals riding at the top of our sport. With four Scicon-sponsored European pro teams racing their way across California this week,  some interesting infographics recently popped up in our inbox breaking down the logistics behind the race. 96 bikes in Scicon AeroComfort bags have made their way across the Atlantic and through countless transfers to bring these four teams to the start lines, and so far none have seen any damage in transit. Fly with us across the break to get more details on this newest iteration of the Scicon’s soft bike travel bag, to get a glimpse at what the pro teams pack, and find out what we think so far…


3ax reinvents the clipless pedals with lateral tilt, putting feet in more natural position

3ax triax clipless pedals with tilt roll for better foot alignment on the road bike

Pronounced “tri-ax”, the new 3ax clipless pedals introduce sideways tilt to your foot, allowing it to move in a more natural motion as you push down. They claim this makes you more comfortable, more powerful and less likely to endure repetitive use injury.

The secret is the ability for the pedals to roll along their longitudinal (nose to tail) axis, with springs inside to add tension so they don’t merely float and feel unstable. It’s only 2º in either direction, but they say it’s enough to maintain better overall foot/ankle/shin alignment. The result? Your knees end up with an average 17% less sideways movement, which means less strain on the joint, and overall efficiency gains of up to 5.47%.

UPDATE: Current prototype weight is 188g per pedal (376g / pair), but they are working to bring that down before production.
