The Canadian Cycling Association (CCA) has suspended downhill mountain bike racer Danika Schroeter for three months after an incident at the podium presentation of the Canadian downhill national championships on July 23.

The women's championship was won for the third time by Michelle Dumaresq. Because Dumaresq is a transsexual, Schroeter and some other Candian female downhillers have been vocal in their opposition to Dumaresq competing in the women's category, according to canadiancyclist.com.

At the podium ceremony, Schroeter wore a t-shirt with the slogan "100% Pure Woman CHAMP 2006" while her supporters shouted insults and obscenities at Dumaresq.

The CCA found that Schroeter's conduct was in breach of its rules governing the conduct of racers, which read, in part, "All license holders shall at all times be properly dressed and behave correctly in all circumstances... They shall refrain from any ... insults or any other improper behavior... They may not in word, gesture, writing or otherwise harm the reputation or question the honour of other license holders... The right of criticism shall be exercised in a motivated and reasonable manner and with moderation."

In its statement announcing the suspension, the CCA said, "The Canadian Cycling Association takes offences of this nature committed by its members very seriously. While athletes have the right to hold and express their opinions, they also have a duty to express them in a manner appropriate to sport and to Canadian society."

Danika Schroeter has until August 11 to appeal.
