So for those that went on the Ome ride know that i bent the shit outta my front rim

, so im looking for a new set of rims and have a question or 2?
so in the process of looking at rims i have noticed that the hubs are VERY expensive lol. whats the difference between the 20mm thru axle and the centerlock and the 6 bolt?? i mean i could look it up but im just to lazy to read all that info lol.
For example i was looking at DT 340 6 bolt 20mm thru axle and the DT340 6 bolt and there is a price dif of 20 bucks.
what the 3 is better in your opinions??
