I converted my Hightower v2 over to a mullet bike. Waiting on the Cascade mullet link now to increase the BB height, and add some extra rear travel, and I'm going to go from 150mm to a Fox38 170mm. Already running a ton of volume spacers on the 150mm fork, so I feel like this should go well. Worst case I'll convert the 38 to a 160mm fork.
