Uusi stock tunnin ajon ennätys?
Hollantilainen Gert Jan Wijers yrittää rikkoa kattamattoman nojapyörän tunnin ajon ennätyksen 24.10.
Tarkoitus on mennä yli 50 km/h pyöränään M5 High Racer tupla levyillä. Mielenkiintoista nähdä miten käy!
Itseäni kiinnostaa erityisesti pyörän valinta. High Racer on tässä tapauksessa kyllä uskoakseni nopeampi, kuin kattamaton lowracer. Onhan tuo High Racer M5:n omien mittaustenkin mukaan nopeampi ihanne olosuhteissa:
High Racer:
ja Lowracer:
Takakate kun lyödään kiinni, eroa tuleekin sitten jo selvästi lowracerin hyväksi. Mutta se ei ole silloin kattamaton ei.
Miehen itsensä kommentteja asiasta (recumbents.com):

After the testrun of last Friday the goal is over 50 km. Perhaps it went to smoothly, makes you wonder more about things that can go wrong then things you can improve. We will see how things go the 24 October.
I really don't understand the high / low controversy. I like both. Each has their own little pros en cons. Which one is the fastest concept? I don't know.
What i do know however is that when you carefully prepare a bike for track use you gain a lot. In Cologne I used the street / commuting / training version on a wooden track an did just under 49 km. The trackversion, which is basically a copy in geometry, stripped down to the essentials with discwheels mounted is considerably faster!
I can't say a thing about wattage. Simply because I never had it measured properly. As an estimate I use the wellknown German Kreuzotter program.
