今日は、マウンテンバイクのメンテナンスをした
Today, I cleaned my mountain bike
前輪と後輪を入れ替えたりして。 after I replaced the rear tire with the front one.
後輪のデコボコがすり減って、真ん中へんはほとんどなくなっちゃったんで。 Why? The rear tire tread has worn down and become almost flat along the center.
後ろのタイヤのほうが減るの早いんだぁ。 A rear tire wears faster than a front one.
きれいになったので、早く乗りたい
It now looks beautiful, so I want to ride it as soon as possible.
