Improvements on the Team Cygnus speedbikes
Winter has started and Team Cygnus uses this time very well. The speedbikes will be made ready for the races in 2018, and more improvements are developed for the bikes. Jan van Steeg has built a great workshop in his backgarden, even though it is small. Everything is nicely done and well insulated. His speedbike sits in the best position. Jan is working on improving the internal ventilation and cooling. Jan has done extensive research into the best position of the naca ducts. The goal is to achieve as much cooling as possible with very little air stream disturbance.
Pieter has improved the aerodynamic shape of his speedbike. Something new for this year is that Pieter will ride with cameras again. Three years ago he tried using cameras, but swapped to a periscope due to problems with the electronics because of the high humidity in the bike. This problem has been solved by well positioned naca ducts. Pieter made a new carbon back hatch in a new mold for this.

Dekra Sunday Evening
First up is Nicci Walde who will try to attack the hour record. Jan-Marcel is riding along in the chase car as an observer for the IHPVA. Nicci is riding not as fast as was hoped, but is very satisfied with the result*.
Pieter is starting as the second for his hour run. The first round he is doing a nice average of a little more than 59km/h. In the third round he is coming in. He still needs more power than with his former bike. Further investigation will have to show if this is due to worse weather circumstances or that more improvement on his bike is needed.
Then a rider of the French team starts for a 200m attempt. The speed is somewhere between 80 and 90 km/h. Jan-Marcel will make a second attempt. Getting started is getting easier. Let's just think that practice makes perfect. The rest of the run is going well, but the wind is too strong for a legal run. With a nice speed of 108.5km/h and more valuable data, we leave the track.
We would like to thank everyone who has helped to make this possible.
In the first place the organisation of this wonderful event. Heike, Christoph, Thomas and Gerard thank you very, very much!
In the second place a warm thank you to all our loyal followers.
And last but not least our family and friends. Without them we could not have put as much time in improving man and machine.

Dekra Sunday Morning
Jan and Jan-Marcel head out to the track before breakfast. Jan can ride for an hour. He will not set a record, but by riding is collecting important power data. With a wealth of data we go to the pits after riding for an hour.
David and Pieter also arrive with breakfast. After a quick breakfast we get the bike ready again. Jan rides another few rounds with the periscope hatch to be able to compare data. This means we can also look at the results of preceding years. After that we go back to the hotel and get some rest.

Dekra Saturday Evening
Jan is the first to ride on the track and clocks a decent 93.3 km/h. He took it relatively easy and did not sprint in the final stretch. He is saving some energy for later in the weekend. The French team makes a round and then Jan-Marcel takes his first ride in the Cygnus Omega.
Starting is very careful. He clearly has to get used to a new way of starting with an extra wheel. He gets off well and makes a decent first round. In the second round he makes a sprint in the final stretch and passes the time registration with 103.2 km/h. Breaking works out good as well, though he might be overdoing it a bit by using the third wheel more than 500 meter before the catch area with still about 20 km/h on the speedometer.
Pieter still has some small problems that get solved later in the evening. He rides a couple of rounds on a good speed. That is very promissing for tomorrow.

Dekra - The Hotel
For everybody who is interested in our very luxurious hotel, we've made some pictures.
Dekra Saturday Morning
Last night we had lots of rain. When we get to the track at 6, everything is still soaking wet. We decide not to ride for the time being. The risk of running a flat or slipping on the wet surface of the track are too big.
Jan moves his speedometer, so he can see his speed and power a bit easier. When looking through a periscoop you focus in the distance, so the speedometer should not be too close. When using the cameras and looking at a screen closer by, the speedometer should also be closer to make focussing easier for the eyes. In the mean time Jan-Marcel attaches the wheel plate on the rear wheel again. The rubbing is solved by that.
Pieter is starting his search for the lost speed.
At 8 we leave the track which is slowly drying. Time for another copious breakfast. This afternoon at 4 we can use the track again.

Dekra Friday Evening
Well in time we are ready at the filling station for the first meeting. The French team arrives just after we did with a new rider and an "old" bike. The team of Universities of Delft/Leiden appear not long after that. Heike is a bit late. After a short round of introductions we head for the track. We also have to wait a bit there before we can finally set foot on the holy oval around 7. We make our quarters in the pits and prepare for riding.
Guillome from the French university enters the track first. After a number of rounds he decides to test the quality of the lawn next to the track. It proves to be less smooth than expected and he slides over the finish line on his side. With just some scratches on the bike and a somewhat deflated ego, they come off pretty good. He appeared to have had trouble with a fogged up windscreen.
Pieter can test the track after that. After a few rounds he comes back into the pits sweaty and unsattisfied. He needs too much energy. Some tape was rubbing and is removed quickly. After another test round it appears that there is more that needs attentions. That means that we will work on that tomorrow morning.
Eventually Jan can also make some laps. It it the first time for him to drive with cameras and he had to get used to that. After four rounds in total we need to leave the track. Something is rubbing slightly, probably the wheel plat on the back wheel. We will also look at that in the morning.
