FLO Cycling – New Year Update

Hello everyone! I hope you all had a good holiday season and safely brought in the new year. I wanted to take a minute to update everyone on where we stand and what’s to be expected in the coming months.
Factory Update
The factories are currently working on producing and testing our parts. If all of the factories hold to their promised dates, we should have our prototypes and be testing by early March. Once we are pleased with the results we will be off to the wind tunnel. We also anticipate this happening in March.  At this time we will be able to show you a few shots of the wheels and release our specs.
Pre-Order
If the factories keep their promises we should be offering our pre-order in late March. The pre-order will be on a first-come-first-served basis. What this means is that the first orders in will be the first orders shipped. After the pre-order, the first wheels should take a ride on the UPS truck in approximately 60-90 days. For example: pre-order ends March 31, wheels ship May 31 – June 30.  The pre-order will guarantee you a set of wheels. Once the pre-order is over and normal sales begin, we will do our best to keep up with inventory. However, there may delays since we have to order our parts from Asia. Please understand.
Payment Types
We have also had a few people asking about the forms of payment we will accept. We will be using PayPal as our payment processor. If you have a PayPal account you can use that. If you do not, the cart will accept Visa, MaterCard, and American Express.
I hope this helps you understand where things currently sit. We are very excited about the coming months and can’t wait to release more info. As always, questions and comments are more than welcome.
Take care,
Jon

Flo Cycling – Computational Fluid Dynamics

I wanted to take a minute and put up a few shots of the computational fluid dynamics (CFD) data we are getting back. The results for the 60mm fairing are in and we are waiting for the 90mm shape. 

First of all, I think these look really cool, but maybe it’s the engineer in me. To clarify, we are modeling the tire, rim, and fairing only. We did not model the spokes or hubs. We tested two unique fairing shapes. I am going to wait to post the numbers until we get the results from the wind tunnel. The wind tunnel tells no lies. What I can tell you is we are getting negative drag (lift) on our 60mm deep fairing. At this point I can assume our 90mm wheel will also return negative drag (lift) values. Keep in mind these are modeled without the spokes or hubs so our drag is bound to increase to some degree. Regardless it’s looking very promising.

We are running our tests from 0-20 degrees of yaw at winds speeds ranging from 5-30 mph.  To generate all of our results will require running a computer 24 hours a day for 21 days straight. I was blown away when I heard this. Below is an email our CFD Engineer sent us.  It helps explain why we need 21 days.

“CFD works by splitting the region of interest (air volume around the wheel) into a number of cells. In our case there are approximately 1.4-1.6 million cells. Results are computed in each individual cell for each iteration.  Results are then sent to the neighboring cells and taken in from neighboring cells. It does this for each iteration in order to reach (in our case) a steady state solution. It takes about 260 iteration to reach a good answer. This is the most (near) perfect mesh I’ve actually ever created.

The first few pictures show the polyhedral mesh (the cells talked about above) for one of the wheel shapes.

The next shot shows the buildup of pressure around the leading edges and the negative pressures on the trailing edge of the tire and fairing.

Lastly here are a few shots of velocity streams around the shape.

I hope you enjoyed this as much as I did. For more great content, please register for our free monthly newsletter at the top of the column on the right. We send links to all the articles we post during the month. Let me know if you have any questions. I’d love to answer them if I can.

FLO Cycling – Vote for Your Favorite Flo Cycling Logo

Let’s be honest: we are engineers, not graphic designers. When we first announced our company, many people mentioned they were not crazy about our logo. A friend was very kind and designed a logo for us (we are not naming him until he gives us the OK). We loved it. We made some minor adjustments and came up with two new options. Please cast your vote below and let us know which logo you like the best.
Just to clarify, when custom colors are ordered, the colored sections will be where your custom color is applied.  This means that all red sections would be replaced with the color of your choice.

Flo Cycling Launches Teaser Site

Flo Cycling Launches Teaser Site – www.flocycling.com

Nine months have passed since I wrote on slowtwitch.com about my brother (Jon Thornham) and I starting an aero wheel company (see link below). Today we want to update you with some very exciting news. Our wheel designs are complete, our materials are selected, and our pricing is in line. If all goes as planned, Flo Cycling will be a reality very soon!
We plan to offer carbon fiber race wheels in 60mm and 90mm depths, along with a lenticular disc. If our meetings at Interbike go as planned, we hope to bring our wheels to market in the first quarter of 2011.
Exact pricing details are not yet available. However, we can say our price range will be in line with our original post.
Please feel free to contact us with any questions or suggestions. We want to know what you think.  We hope to get your input along the way with aesthetics, graphics, type of carbon weave, etc. Take a minute to visit our teaser site where you can register for email updates or send us a message. Be sure to follow us on Facebook, Blogger, and Twitter.
Thank you for your interest and support,
Chris Thornham
