Accidents resulting from faulty tightening of wheels, handlebars or toe-straps or the blockage of the chainset are unrecognised and result in disqualification. Helmets are compulsory. Riders are not allowed to obstruct faster competitors who are trying to overtake them.
Riders can protest about obstruction or tugging after the race is completed.
