商品描述

動力傳遞。五通軸承是將您的踩踏施力，傳遞到車身的關鍵部件。因此摩擦力極小化和高負載耐受性是決定五通軸承優劣與否的關鍵因素。結合了輕量化鋁合金承座，CeramicSpeed 五通軸承強化傳動剛性並提供最佳的動力傳遞。我們所有的五通軸承：皆是使用 CeramicSpeed 培林，以優異的耐衝擊強度、真圓度、平整度和硬度著稱。我們的五通軸承也有提供 CeramicSpeed 鍍層培林版本。我們的特殊鍍層進一步減少摩擦阻力，並提升培林使用壽命。鍍層培林具有更高的抗摩秏性能，且幾乎不受各種汙染因素的腐蝕傷害，如水份、塵土…等。擁用超過 150 種以上的五通軸承規格：CeramicSpeed 產品幾乎可對應市場上全部的五通標準。許多高級自行車製造商都採用：CeramicSpeed 五通軸承，作為車架組的選購升級配備。配備 CeramicSpeed 五通軸承後，曲柄迴旋的順暢程度看得見、摸得著，這就是無償增速的完美示範。

T47 is a standard created by custom framebuilders. It’s threaded, has an inner diameter of 47mm, and is 86mm wide. Ithas the design benefits of being oversized and wide, but also the practicalbenefits of threads.

This kit pairs those bb’s with 30mm spindlecranks. The cups have CeramicSpeed bearings pressed in. There are two bearingoptions. The Standard Bearing has CeramicSpeed Balls and hardened-steel races.The Coated Bearing has the same balls running on a 3-micron thick coatingplaced on top of those hardened-steel races for greater durability and lessfriction still.

This BB is compatible with 86mm frames, andalso compatible with TREK T47 85.5mm wide frames.

Technical Data

With the benefits of both oversized shellsand the tight fit of threading, T47 has the best of both worlds. These cups andbearings make it possible to run stiff and light 30mm spindle cranks, likethose from Rotor and FSA’s 386EVO standard.

Standard Bearings reduce drag by 75% versusstock bottom brackets, dropping down to 0.3-0.4 watts per set. This is theresult of hardened-steel races rolling ceramic balls that are 100% smoother and15% harder than the ceramic competition. They also last longer.

Coated Bearings feature an even longerlifespan and even lower drag. Life increases by 60% and drag drops by 50%compared to our Standard.

Applied to the bearings at the factory isAll Round Grease. It can be replaced for lower drag Race Day Grease, or higherdurability Long Life Grease, which adds a bit of drag but stays in when ridingthrough messy conditions.

This BB is compatible with 86mm frames, andalso compatible with TREK T47 85.5mm wide frames.
