加拿大卫生部召回中国产“Tektro”牌自行车刹车把
　　日，加拿大卫生部与Specialized Canada Inc.联合宣布对中国产“Tektro”牌自行车刹车把实施自愿性召回。原因为该刹车把上调节器的帽和闸线易从固定位置滑出，致使刹车失灵，有致骑车者对车失去控制而发生撞车事故。　　此次被召回的Tektro TL-83自行车刹车把专用于2011款S-Works Shiv自行车框架、2012款S-Works Shiv TT自行车框架的空气动力车把上，同时还作为2012 S-Works Shiv X2自行车框架原装配件出售，是TL-720款的改良版，黑色铝合金材质，顶端有快速释放槽，产品型号“TL-720”标在刹车把侧面。此次被召回的商品数量约为34个。　　据了解，该自行车刹车把自2010年6月至2012年9月加拿大销售。截至目前，加拿大卫生部与Specialized Canada Inc.均未收到任何事故报告。　　对此，加拿大卫生部建议消费者立即停止使用安装有被召回刹车把的自行车，并与Specialized Canada Inc.授权经销商联系免费更换刹车把。
