Perfectly made high quality product. Fitted to my Super 73 RXE like a glove. Original was 44 tooth which I replaced with a Deckas 52 tooth. The desired outcome was more range and ability to use the 10 speed efficiently. Highly recommended this product.

GIANT ESCAPE R DISK LTDをシングル化するためラウンド42Tを購入。 クランクはそのまま使用、ボルトも短く加工すればオリジナルを使用出来ました。 (コッタレス抜かなくても付け替え可) ナローワイドなので大丈夫かなとは思いますが、私は念のためチェーン落ち防止デバイスを取付けています。 音は静かな方だと思います。 デザインにセンスを感じないので星ひとつ減らしましたw
