【Fit】GEAR Shaft fis6183 ["Hybrid"] [] 3 (24.0mm) Clear 's Japan Review

All 3 shafts broke after 3 hours of use.
I prefer hybrid shafts because they are high strength and hard to break, but since there are no hybrids available, I bought 3 sets of gear shafts in different lengths as a trial to buy carbon, but all of them broke (red, black and blue). (Red, black, and blue) Specifically, they break cleanly at the joint with the barrel.
The gear shaft has a gap at the joint with the flight compared to the normal type, so the spin is a little bit stiff. (The O-ring can be inserted at the joint with the barrel, so it will not stick out even if an O-ring is inserted.
If you prefer a slimmer design, we recommend the high-strength version. (Carbon is also good, but it is much harder to break and more cost-effective.)
If you really want a hybrid like me, it is much cheaper to buy carbon.

In summary, the O-rings are the worst in terms of strength, but in terms of performance, they don't stick out and don't loosen. The O-rings do not stick out and do not loosen, but they do have a little bit of stickiness, so if you don't want to have a little bit of stickiness, then go for the normal type.
If you have a good rotation rate and don't want the shaft to be loose, I think the gear shaft carbon is the way to go.
