As mentioned before for non beadlocks method has some great choices with the nv305 that @midnightljr uses and has a big enough hub for lockout as well as 701 bead grip rims which don’t have a big enough hub but I do like the idea of a little extra something to hold the bead without beadlocks. Both will need some amount of spacer to get to the 4in of backspacing equivalent unless running lockouts.
Another option as far as beadlocks seem to go is the trail ready and race line rt232 monster bead locks (seen a lot more race lines than trail ready thus I looked into them more) that do offer a 4in back spacing wheel and a bigger hub than the methods (.82in bigger). So I think you could run 4.75in back spacing with a hub kit up front and run the 4in in the rear as an option for no spacers which I think is a cool thing. At 11 pounds heavier than method non bead locks but the whole bead lock or not discussion is another topic as most really don’t need it but they do offer benefits.
Curious to see if my thoughts with both methods and race line make sense and I’m not missing anything vital or misunderstanding it.
