【Fit】GEAR Shaft fis5044 ["Hybrid"] [] 4 (28.5mm) Clear 's Japan Review

It is as easy to use and as strong as advertised. It is easier to install than conventional slot locks, and the holding power is unquestionable. The strength is also very strong and secure, just like Raro's Clear. I think this will be the new standard from now on.

There are many variations in length, so there ◎.
However, the strength is weak.
The barrel side has never broken, but the connection part of the flight side often breaks.
So the flights are sometimes useless.
I think it is a great shaft if the strength is improved.
