【Fit】GEAR Shaft fis6085 ["Slim"] ["Spin"] 3 (24.0mm) White 's Japan Review

This is the most easily available and most complete shaft with rotating flights.

It is a little bit complicated to use with some barrels, because of the difference of the barrels...
The size list of length would be appreciated...
but it would be even more appreciated if the maximum diameter is also indicated...

And when it breaks, it breaks.
This is quite troublesome, and it breaks off right in the middle of the threaded part.
Prepare a shaft remover!

It is a shaft exclusively for FIT flights, and while it has a simple shape that is attached by inserting a dedicated flight, the locking type holds the flight in place, while the spinning type rotates the flight to reduce bouncing due to darts interfering with each other.
I preferred the clear coloring with lame dyeing, but I decided to use the GEAR series because the running cost of a relatively expensive FIT is too high to have many broken darts. Although there were times when they were bounced off the dartboard, I would break only one dart per month if I was unlucky, so I keep using them.
There are three types of shaft shapes, but I didn't feel the weight change that much, so I think you should choose Slim for its clean look and good hooking when you grip the shaft lightly, Hybrid if you grip the shaft lightly and dislike hooking and want lightness, and Normal if you want to emphasize strength. If you want to focus on strength, I think you should choose the normal type.
The spin type shaft rattles slightly when the flight is attached, so those who do not need it to rotate should choose the lock type.
The lengths are (1) 13mm, (2) 18mm, (3) 24mm, (4) 28.5mm, (5) 31mm, (6) 35mm, (7) 38.5mm, and (8) 42.5mm, so you can choose according to your preference.
