【Fit】GEAR Shaft fis6042 ["Normal"] [] 1 (13.0mm) 's Japan Review

It will not break unless you are very careful.
There is almost no sensation of loosening of the flight.
There are many lengths to choose from, so you can find the one that fits you best.

An improved version of the Fit shaft, the Fit shaft gear.
CosmoDarts claims that it is "very strong" but it breaks quite easily.
It is not a cheap shaft, so if it breaks, it will damage your wallet quite a bit.
The lengths range from #1 to #8, normal, slim, and medium thicknesses, and spin and lock flight retention types.
The fact that there are so many choices puts it far ahead of other shafts.
The small number of component parts means that even if you use the spin type, it does not shake catastrophically and you will not be stressed.

I thought it was difficult to compare one shaft with another, so I have made a template with my own ideas.
It is a shaft exclusively for FIT flights, and while it is 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.

I'm using (1) 13mm.
If it falls on the floor when it is hit by a spider, etc.
90% probability of breaking from the root of the screw part.
I throw about 5 hours a day and on average 3 darts break.
Since the O-ring of the Cosmo Darts is installed
It is not broken by loosening.

My friend is using the same darts as this one (5) 31mm.
He says that even if it breaks in a month, it is about one.

I wonder if it is easy to break when it is short.
