【ロードバイク】初心者親子で熱海～伊東の往復 初ライド！新車のピナレロプリンスとボッテキアに問題発生！坂道だらけでトラブルの連続　コースに苦戦

The first petit expedition from the purchase of a road bike! Brake trouble with the newly delivered PINARELLO PRINCE FX DISK Di2 and BOTTECCHIA 8AVIO EVO RED LAB, which I bought with a new car. Standing up, damaged shifter? Beginners themselves assault experience, please refer to everyone
