延長桿 2吋/5公分（2入組）

The set gives you a nice range for fine-tuning the adjustment on my device, and the 5cm length is exactly what I needed to step up from the smaller bars. One bar had a slightly rougher edge than the other, but it's nothing a quick sanding didn't fix.

The two bars are exactly the 5cm length I needed to fine-tune my setup, and they lock in place without any wobble that I’ve noticed. Only gripe is the packaging was a bit tight, but the bars themselves feel solid and do the job fine.
