有啲難比較，但我會覺得公路車輕鬆啲。 P line 唔改裝的話，前餅係50齒。之前有師兄覺得50太重要換到44。對我嚟講，50齒上小山坡或斜路都唔難。不過如果個斜路係優景里，照上到，但明顯公路車會係個更好選擇。 您提出嘅公路車，前34配後34個齒比係1:1。再加上可以揸上把，會比較容易發力，因此咁樣比較，公路車會輕鬆啲。但係11-34齒比設計係為咗上大山，因此犧牲咗連綿啲嘅齒距，踩平路會不及11-28連綿。要睇吓個斜坡同體能需唔需要用到11-34。 有啲難比較係因為兩架車明顯個設計係唔同。P line 講摺疊同輕量，11-34公路車或者Gravel 都係上大山。上山上會係後者優勝，但摺疊、操控性、設計都好唔一樣。所以要睇返你真正需求。就我而言，我用C line 上小山坡都唔會用到最細個齒比，反而我會覺得太輕腳。 希望幫到您。
