Race face turbine cinch for fat bike, 170 mm rear end. This crank fit my 2015 specialized fatboy SE with a 190mm rear end perfect. It didnt make sense to me that a 170 mm rear end crank would fit my fatboy that uses 190mm hub, but it did.
Race Face Cinch turbine fat bike 170mm rear end and 175mm crank arm length came with one 2.5mm spindle spacer.
Race face PF30 x 100mm bottom bracket came with two 1.5mm spindle spacers.
Per Race Face to fit my fatboy with Race Face PF30x100mm BB, you need to put a 2.5mm 1.5mm spindle spacer on the drive side and a 1.5mm spindle spacer on the "non" drive side. Plus, I had to turn the Cinch chainring around so the raceface etching was facing the bottom bracket. This made the chainline more off the crank, end result, the chainline and the Qfactor was perfect. Spindle spacers supplied were alloy, dont know how plastic ones will work.
Ok, I hope I answered all the questions I had before I installed the crank and BB.
