HMX Swift V2 線性軸 出廠潤滑版 (10顆)

Installed these in my daily driver and the smoothness right out of the bag is unreal — no break-in needed. The factory lube is applied evenly with zero over-lubing, and the sound is a clean, deep clack.

The new LY stem blend feels noticeably smoother on the upstroke compared to what I remember from the originals. The factory lube is just enough, too, so they’re good to go right out of the bag for a linear build.

These V2s are a clear upgrade—the new LY stem material makes them feel noticeably smoother right out of the box. The factory lube job is perfectly even, saving me the hassle of doing it myself. They’re exactly what I wanted for my linear build.
