お近くの自転車販売店にて、フォークの総合チェックをご依頼ください。

SR SUNTOURは、目安として25時間使用毎に、当社純正のConpannaグリース又はテフロンベースの潤滑剤を推奨いたします。

すべてのSR SUNTLOURフォークは、独自のグリースを使用して当社工場で生産されています。 このグリースは時間とともに分解し、油のような外観を呈することがあります。その際は、乾いた布で特にスタンチオンチューブから拭き取ってください。メンテナンスの目安として、およそ50時間或いはそれ以前に新しいグリースアップされることをお勧めします。

この様な状況は正常で、空気は実際にはポンプから流れており、リヤショックやフォークからではありません。 ポンプを再度取り付けるとき、ポンプに対して約10〜15 psiの圧力がかかる場合があり、その際、ポンプのゲージにエアスプリングよりも低い圧力を表示させることがあります。再度取扱説明書を参照いただき、適切な空気圧とSAGセッティングを行ってください。

SAGとは、自転車に乗ったときの最初のフォーク移動量です。この調整により、あなたのフォークまたはリヤショックの最適なパフォーマンスを可能にします。

 一般的に言って、120mm以下のトラベルのフォークは15〜20％のSAG調整を推奨いたします。一方120mmを超えるトラベルのサスペンションフォークは、25〜30％のSAG設定を推奨いたします。
