I noted the report today regarding banning studs, presumeably a new ban to keep riders from using tires with studs in icy conditions. Studs have always been banned. The latest published regulations for general equipment is November 13 of last year. The particular regulation cited has not changed in any form since 2005 and the no stud regulation has not changed since I was first aware of it in 1993.

I just reread the UCI rules posted on the UCI website and could not find a prohibition on the use of studded tires. Can you point them out to me?
Thanks
In any case how or where is a stud defined?

How is a stud defined by the UCI? I can't find a definition anywhere.

the (re)confirmation came when the UCI caught wind of the rumour that Dugast had made a new spiked tire, the Diabolo ... Sven had a good test on an iceskating track in Eindhoven on those tires ...


“1.3.018:Wheels of the bicycle may vary in diameter between 70 cm maximum and 55 cm minimum, including the tyre. For the cyclo-cross bicycle the width of the tyre shall not exceed 35 mm and it may not incorporate any form of spike or stud.”
