Because it is not possible to go below 33 teeth on a 110 BCD crankset without some tricks. This is what Praxis had to do:

"For this five-bolt crank and its 110mm spider Praxis has come up with a clever fourth way: dispense with the chainring nut and screw the bolt straight into the inner ring. That provides the necessary couple of millimetres of extra space needed for a 32-tooth ring.

The hole in the inner ring is very close to the bottom of a trough between teeth, though, so you can’t go smaller with this trick. And you probably can’t just put the Praxis rings on a 110mm five-arm chainset that you happen to have spare. To make room for the chain on the 32-tooth ring, Praxis has machined a shoulder into the arm of the crank; without it, the chain will almost certainly hit the spider arm and skip."
