Fatlab fat bike hub sets front and rear in the combination you choose! either 135mm or 150mm front and 170/177 or 190/197 rear with shimano or sram XD driver. end caps can be Qr, TA15 front and QR or TA12 rear!
Best value I’ve found. I have purchased 2 sets. Months apart, Quality the same.
Sound engagement from hub is perfect, it’s there, but not obnoxious.
Would recommend.
