That's a good point. 20 more engagements and under 20% of the price of a profile. I personally if i had the money would go for a chris king, even though it is un needed and a waste of money. but I would go for a ENO over a profile though, It has more engagements and is so easy to service and take off since its not all tied into your wheel, and you don't hear any bad stories about how they have broke or keep constantly skipping unlike a profile. Me and my mate have Eno's and they rock, as long as they are serviced and cleaned out properly they are amazing. I can see the point in having a cassette hub on a stock but it just seems a bit pointless on a mod to be honest. Unless its a king .
