That would depend upon how you define "best."Which is the best rear wheel spacer for a bx2380 ?
I second this recommendation - I have the 2" spacers from BroTek on my 1860. Top quality part.I have 2in Bro-tek on my BX2370. I highly recommend them. A quality product machined from solid aluminum specific to each model. There are others that as good but not better.
