The August edition of BMX Plus! has an interesting column written by Mike Day about his new prototype Speed Series bike.
In the article, Mike talks about his desire to put together “the biggest-wheeled bike that was allowed to race” in the 20- inch class.
(Note: the bike in the video is not the prototype Speed Series…the video just highlights how smooth Mike is)
According to the UCI rule book that meant the diameter of the wheels, including the inflated tires, could not exceed 22 1/2 inches (57 cm).
Once he determined the parameters, Mike worked with GT and Tioga, to design a bike that featured a larger-diameter rim and low profile tire.
The result? A combined diameter just a 1/8 inch smaller than the maximum size allowed by USA BMX and UCI.
Pretty interesting stuff….especially given USA BMX stance that 22″ bikes belong in the cruiser class.
Wonder if this will prompt USA BMX or the UCI to make an announcement about this sort of thing…especially if the rumors are true regarding other companies working on their own versions of this.
