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.


Cervelo adds two Shades of Grey to entry-level road, triathlon bikes

2015 Cervelo P2 triathlon, time trial bike in black and white
Where some competitive racers would happily ride a pink and purple paisley frame if it promised to make them faster, entry level consumers don’t make decisions on the same criteria. Their choice in the bike shop may be partly influenced by something that seems trivial to a die-hard racer. Like a bike’s contours, graphics or colors, for example

Cervelo has just announced their entry level R2 road and P2 triathlon/time trial bikes are now available with two color schemes for each – The R2 now comes in a grey/orange option and the P2 in a glossy black and white. Now entry level buyers can get a bike that offers performance well beyond its price tag (as both of these bikes seek to do) while having it appeal to them for reasons beyond saving seconds.

SOC15: Xentis Squad 4.2 and 5.8 Wheels Get Ultrawide for 2016

Xentis squad disc wider 42 58 mm deep wheels carbon (2)

No matter how good a wheel is today, the big question everyone seems to be asking is yeah, but how wide is the rim? This seems to apply equally to both mountain or road bikes where the width of a rim can have a drastic effect on the shape and performance of the tire. Mountain biking seems to be taking this concept to the extremes lately, but road bikes aren’t far behind if you consider just how narrow rims and tires were not that long ago.

Having already subscribed to the trend on their Squad 7.8 deep dish carbon wheels, Xentis is now adding substantial width to both their Squad 4.2 and 5.8 road wheels in tubular and clincher as well as rim or disc models. Details next…

SOC15: Garmin makes power meter pedals easier to install w/ Vector 2.0

Garmin’s Vector 2 power meter pedal system has received a slight update to make it a bit more durable and a little easier to install.

Gone are the washers, replaced with a hinged clamp that simply wraps around the pedal spindle and bolts into place. That makes the pedal pods easier to line up in the correct position.

The pods themselves are made of a new, tougher material that’s the same as their out front mounts. They say that resin is actually tougher than the original alloy mounts. It wasn’t a matter of toughness under impact, because you’re not really going to hit them on anything if they’re positioned properly…it was more about holding up to repeated removal and installation.


All-New Rotor INpower hides power meter tech inside crank spindle

Rotor INpower crankset powermeter inside the spindle

The antenna and battery cap on the non-drive crank is all you’ll see of the new INpower power meter…everything else is tucked inside the spindle.

The Rotor INPower is a clever new take on the crank-based power meter that puts all of the electronics inside the axle, which not only protects it, but keeps the rotational mass at the center.

But the location of the electronics is just part of the story. Rotor, which is known mostly for their ovalized chainrings, can show “different” power readings when those chainrings are used on standard spider-based power meters. This happens because the ovalized shape changes the zones of rotational speed at which you’re able to turn the pedals over by making it easier in your dead spots and harder in your power zones. The result, from our own experience, is that the overall pedal stroke is much smoother and the rotational speed seems more consistent to our legs, but they say a spider-based strain gauge may not see it that way.

The design also lets them use the same power meter across their entire range of cranks regardless of the arms, making it perfect for road, triathlon, cyclocross and mountain bikes…
