Personally I think the reason the Toronto team crashed so many times (3 times at Northbook and once at Kenosha?) is because the bikes have no front suspension. It doesn't take much of a bump to put a stiff and heavy bike that is running at high speeds and laid way over in a corner past the limit of adhesion of little skinny racing tires.

Did anybody get pictures of the streamliners? I'm looking for a side shot of the Cuda-W with the new front wheel fairing.

Thanks,

-Warren.

Here's a nice writeup that I just discovered from University of Toronto.
http://www.aerovelo.com/2012/07/19/northbrook-and-kenosha/
There was a link to this off Professor Jun's blog. It was written by Marc, who did the high-speed crash with Vortex at Kenosha. On Jun's blog it shows the bikes parked while everyone is working on making the human powered helicopter fly by the end of the summer! Good luck to everyone! We want to see more history made!

Sorry it took so long, but there a number of great photos taken by Jim Mathews on the Cheddar Challenge race site (cheddarchallenge.webs.com).

Yes, I ran 155's. They allowed me to draft Mike 10mm closer than last year.

Good to know that the power is still there with the shorter cranks. That explains Mikes speed then: the bow wave effect, you know. Or filling the void, take your pick.

Thanks to everyone who came to the 20th Cheddar Challenge! Despite the hot weather, we had a good turnout, with some new faces. And thanks to the all those who helped; our volunteers--Bob Jung and Jim Mathews, who did setup/takedown, registration, photography, and helped with flagging/timing, and the racers who pitched in--Warren and Bruce, who did timing/results, and Jim Iwaskow!

Chris pointed out that Jim found that you can Google an article from the Kenosha News. It was well done and worth a peek. You can see additional photos on their website (kenoshanews.com) by going to the Customer Service tab, then the Photos tab, and then View Galleries and select the July 16th set. There are good photos of Warren, Thom, Gary, Jim & Dora, and packs of stock racers.

And congratulations to our 1K World Record setters--Thom and Dora!

I think he's putting out 250W. Remember this was a short race.

I would hope for the former as it's tougher to get stronger than it is to build a faster bike.
Maybe.

We want to see MM on his M1 in a flat, non-windy, no braking, TT with a power meter!

From Jack Rabbit Jimmy... copy this into Google:

"cheddar kenosha world record"

And you'll see some pics and a nice article in the Kenosha News.

I gots to get me one of those. Then again, with the same weight and relative body position, I just have to stay near Sean.
sean costin Posted - 07/16/2012 : 18:43:42
larry,
Here is my powertap. I derailed at the start and Mike caught me on Lap 2 or 3. I hung on his tail until we hit lap 35 when I decided to try to unlap myself. I was able to get about 1/3 lap, but I could not sustain the effort and blew up. The speeds are pretty exciting, but once again my watts are not.

Here are the records runs that I recorded. The only I don't have is Thom's 200 meter run. Hopefully someone else recorded it for WRRA record requirements.

Larry, Sean will probably confirm this, but I think he said he was at 220 drafting Mike. Assuming similar aerodynamics I now have an idea of about where my heart rips open and my legs break. Sean said that was managable for him, but to leave the draft and pass Mike required ridiculous, unsustainable power. Like I said, Mowett is on another level(and still improving). YIKES!

Great races.

Godspeed,

Chris did you do the kilo at Kenosha on your trike? I don't seem to have a time for you. If you did, I'll go hunt it down for you.

John, we were typing at the same time. Really good meeting you. Big fun ahead.
Speedbiker Posted - 07/16/2012 : 06:59:33
I would also like to mention that John Burrell was at the race with his new Morciglio M1. He seemed to be having trouble getting it going, and certainly couldn't have been happy with is 26 mph 200m speed. I secretly snickered to myself about not worrying about him. This seemed justified when I quickly lapped him in the 50. But then I was baffled because I didn't lap him again. What the heck, did he quit. No, HE WAS MATCHING MY SPEED A HALF A LAP BACK! Yikes, again! I don't want to think about what his speed will level off at. The masters catagory is heating up. Best of all, John fit right in our wacky, fun loving, fast riding group.

At the Northbrook Velodrome, July 14: I want to thank everyone for the great support I got racing my M1 for the first time. Dennis and Tom changed my front flat twice. Mike cut and mounted a new seat pad. Warren had many helpful tips. Sean really worked hard to make it a great race day. I really appreciated the atmosphere and friendship. Thank you all.

Notice Mr Mowett's max speed. Remember, this was on a track. Yikes!

Also, big THANKS to Sean, Dan, and all the people who made it possible for us to experience these fantastic speeds.
warren Posted - 07/16/2012 : 06:43:21
I see this all the time at Northbrook with the streamliner racing results. My speedo says 38MPH and above for the whole race and the official results say something dismal like 36 MPH. I'm pretty sure that this is because the faster vehicles spend a lot of time passing on the outside. What Math wiz can figure out how much longer a 383 meter oval is when you add 3 meters to the the circumference of each end of the track. Hmm. If it were a 383M circle with our buddy 2pi we can find that the radius would be 60.98M. Add 3 to that and the circumference would be 401 M, so if the track were a circle, the AMB system would read a speed 95% of the speed shown on the bike computer. 30 MPH x .95 = 28.5. 40MPH x .95 = 38.

Moral of the story is to hug the black line and just knock all the slower riders out of the way :)
