Description
SHIMANO 4700系のTiagraの登場で、エントリーグレードのコンポーネントにもSHIMANOの誇る素早いシフティングをはじめとする先進技術が採用されました。 しかしその代償として今まで使用可能であったダウンチューブシフターやバーエンドコントローラーが使えなくなってしまったのです。 その隙間を埋めるべく登場したのがこのサムシフターです。
SHIMANO Tiagra/4700系を動かすことのできるダウンチューブシフターは、このmicroSHIFTだけとなっています。
バーエンドシフターは、ドロップバーバイクにおける最もシンプルで信頼性の高い変速方法です。変速テンションの調整、可動部品の少なさにより壊れにくく調整も容易で、万一の機械的な問題が発生した場合に柔軟性を発揮します。地球上のあらゆる場所のツーリングや、友人とのサイクリングに最適です。
[FEATURE]
- 高精度で加工されたアルミニウム製
- 革新的なトルクボルトによりシフト操作力を調整可能
- 右シフターはインデックスもしくはフリクションモードに変更可能
