Bike Fitting

透過三次短騎實戰，以可逆、小幅、單變因原則調整公路車坐墊高度。關鍵限制是每輪只驗證一項座高假設；短騎只能觀察短期反應，不能證明整體安全。以基準位置、相同路線與明確停止條件判斷是否改善，並控制調整風險。

When pressure at the front of your knee or numbness in your foot builds during the second half of a ride, saddle height is one variable worth examining. This guide uses three 30–45 minute rides to make small, reversible changes, one variable at a time. The critical constraint is simple: each round tests only one saddle-height hypothesis, while short rides show short-term response rather than proving long-term safety. Start from a measured baseline, repeat the same route, and use clear stop conditions to judge whether comfort improves while keeping adjustment risk controlled.
