不論是跑0或跑3, 在Fulcrum跑系列的使用手冊注意事項有兩段話節錄如下: If you weigh over 109 kg/240 lbs we advise you not to use this product. If you weigh over 82 kg/180 lbs, you must be especially vigilant and have your bicycle inspected more frequently.
也有人建議Mavic, 不過Mavic不管是板輪或其他公路車輪組的建議值都一樣, 而且更嚴格一點, Mavic的技術手冊也有這段話: Recommended maximum weight of the cyclist and equipment: 100 kg.
