It's built from aluminum, and features smaller, more widely distributed splines that limit cog damage for long-term use and durability. While the XT cassette packs the same gear ranges as its XTR sibling, its construction skips the featherweight titanium, so it does scale in a little bit heavier than its partner. It makes for an ideal choice for riders who are looking for top-lev...

love the XT! the XTR is fine if you have excess cash, but for the weight difference, I will stick with XT or SLX moving forward.

デオーレから、こちらのデオーレXTに変更しました。漕ぎ出しから、自分の感覚を疑うレベルで軽く感じて、ビックリです。チェーンのかかりがスムーズで、抵抗感が消えます。

Used on a backup set of wheels. Not much difference between the XT and XTR, but the price and weight.
