Let’s get Technical: Why the Different Shapes?

Feb 20, 2018

In this weeks blog, we’ll be divining into a little technical talk about our frame design, specifically the rear end. Why it looks different from others and how it benefits you. We will also share what’s new inside Ventum and have a sneak peek at next weeks blog.

So, let’s get techy! What does asymmetrical mean? The definition of asymmetrical is having two sides or halves that are not the same, i.e. not symmetrical. The chainstays of the Ventum One and Z have an asymmetrical design. We came to the shape from extensive structural and aerodynamic testing,while the final tuning of the stays came from road testing/handling of the bike. 

The chainstays on the Ventum frame measure 9mm shorter than traditional road and tt bikes, while also positioning the rear wheel to sit further into the wheel well.  The rider gains a more balanced weight distribution over the bottom bracket, which  improves handling and cornering abilities in comparison to other triathlon bicycles.
The non-drive side top edge is horizontal to the ground, this is done so when the air is broken for the first time at the leading edge of the BB shell, the air is then kept until the trailing edge of the bike. By doing this, it minimizes the amount of surface that will break the air.
The drive-side chainstay has a very different appearance and is designed to shield the derailleur and cassette from the wind. There is a lot of turbulence created on the gears and the Ventum chainstay helps to push the air around this high drag area.
The non-drive side is very stiff in a vertical plane and the drive side very stiff laterally. Once a rear wheel is installed it ties both sides together. Creating a stiff rear end that is compliant but responsive.
The first time you ride a Ventum you will notice the strange feeling of it being extremely stiff but subtle. You can feel every pedal stroke want to push you forward whilst remaining comfortable.
Aside from the aerodynamic and ride quality advantages, this design allows you to mount the Ventum One and Z to any trainer with ease. Allowing you to stay on top of your training in the midst of heavy winter.

Now on to whats new inside Ventum.

Ventum acquires professional mechanic, Jeff Yingling, for 2018 and onward. 

Many professional and amateur athletes alike, know Jeff for his flat caps, sunglasses and skills on the tools. But in the bicycle industry he is known for his technical knowledge and creativity. Here at Ventum, Jeff will be aiding in the design of future bikes/products and assisting the marketing team with Social Media content creation and management. 

“When I heard Jeff was available, I knew we had to have him on the Ventum team. He has seen the growth of Ventum since day one, brings a new perspective, fresh ideas and is all around a great guy. Only set back is his hair, its way to short.”-Says Diaa Nour, co founder of Ventum. 

“I felt it was only a matter of time before I joined Diaa, Jimmy and the Ventum team. We all go back a few years and have always been close in the industry, sharing crazy ideas/napkin drawings and just having fun. I’m really excited for this new venture as I get to be as creative as I want from Social Media/Marketing projects to designing new components or even frames. I get to work with my friends and support our professional athletes on the tools. What more could I really ask for?”- Jeff Yingling.

Keep your eye out for Jeff at the races inside the Ventum tent and be sure to say hi. He is always willing to talk shop and make sure you have the fastest set up possible come race day.
