Crankbrothers fixed my mistake. I ordered the correct product but they actually recommended the steel version instead of the alloy version because I have an E Bike. So they took care of the exchange no problem! I also called for tech support when installing the new freehub body. I went from shimano to sram and they gave me strp by step instructions on how to swap everything. Love Crankbrothers. Good team all around!

Like all Crankbrothers stuff this is very good. The new rachet hub that this went is great. Easy on and off to change the freehub body.
