五通軸承 - BSA MTB Bottom Brackets
概論
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。

English-threaded bottom brackets are known as BSA; it comes from British Standard Cycle. English threading on MTBs mean a 73mm wide, 34mm inside diameter shell with reverse threading on the drive side. It’s the most common threaded standard employed today. This kit works with 24mm diameter spindle cranks, found on Shimano, FSA, Rotor, among others.
The cups have one of two bearings installed. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and lower mechanical friction.
包裝盒內含:
Art-No. | 適合以下框架/軸 | Thread |
顏色 | 材料 | 培林 | 兼容 | Coated 鍍層版本 |
101449 | External BSA / 29mm MTB | BSA | 黑 | Alloy | CS 61805 Coated | Shimano, FSA, Rotor a.o. 24mm | ✔ |
101451 | External BSA / 29mm MTB | BSA | 紅 | Alloy | CS 61805 Coated | Shimano, FSA, Rotor a.o. 24mm | ✔ |
For MTBs, English threading, thanks to history, is pretty much the one threaded standard. It works great. 24mm spindles easily fit through the shell, allow for large bearings to be employed in the outside cups, rarely creak, and seal up well.
Lots of things that slow bikes down; bearings shouldn’t be among them. CeramicSpeed Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. The bearings last at least 3x longer than other bearings. Coated have even less drag.
These bearings come packed with Long Life Grease, best for muddy conditions. For less drag and are riding in cleaner environs, you can coat the bearings with either All Round Grease or lowest drag Race Day Grease, which is best in the clean conditions.
