我們不想引戰，但我們必須承認傳統壓入式中軸存在一些問題。它們容易產生異音吱吱作響，並且必須使用麻煩的壓入工具進行安裝和拆卸。 TOKEN的NINJA底部支架解決了吱吱聲的問題，提高了軸承壽命並增加了底部支架的剛性。

一開始我們的Fusion專利技術是塑料和纖維兩種的複合材質，並包覆在軸承外珠軌上。如此一來可以使其可以精確加工並緊貼在車架中，它不會在框架中移動，更不會產生聽起來就像奶奶膝蓋關節炎的咔噠聲和吱吱聲。但塑料和纖維不能很好地支撐軸承，導致軸承可能會過早磨損。

因此我們將軸承安裝在鋁合金外殼中，並用塑料和纖維包裹在鋁合金外殼上。這三種材料的結合為軸承提供了堅固的平台，可以延長它們的壽命。許多消費這對此感到滿意，但我們更進一步延伸鋁合金外殼，使左右兩側鎖定在一起。這將使車架、曲柄和中軸鎖在一起，並提供無與倫比的剛性。

NINJA中軸不僅解決了底部支架嘈雜的問題，它實際上改善了底部支架的使用壽命，使您的自行車更加堅硬。把它放在你的自行車上，你會想知道為什麼你沒有盡早安裝NINJA中軸。

 

We don’t want to start a fight but we think it’s fair to claim that there are some problems with press fit bottom brackets. They creak, don’t last all that long and are installed and removed with tools that cavemen would recognise. TOKEN’s NINJA bottom bracket solves the creaking issues, improves bearing life and adds stiffness to the bottom bracket.

We start with our Fusion technology; it is a combination of plastic and fibre that cover an alloy bottom bracket shell. The composite material allows it to be precisely machined and fit snugly in the frame so it doesn’t move in the frame and sound like grandma’s clicking and creaking arthritic knees. But plastic and fibre don’t do a good job of supporting bearings; poorly supported bearings can wear prematurely.

We house the bearings in an alloy shell and wrap it with plastic and fibre. This fusion of the three materials provides the bearings a solid platform to sit on and extends their lives. A lot of people would be satisfied with this, but we went even further by extending the alloy shell so the right and left sides lock together. This locks the frame, cranks and bottom bracket together and provides unparalleled stiffness.

The NINJA bottom bracket is can be purchased individually or in a package that includes adapters to fit several different frame and crankset combinations.

The NINJA bottom bracket doesn’t just solve the problem of noisy bottom brackets - it actually improves the life of the bottom bracket and makes your bike stiffer. There aren’t many times a replacement part actually improves your bike but put one on your bike and you’ll wonder why you didn’t install a NINJA sooner.
