BB is very high on the 456. Anything above 300mm and you won't notice bb height on a hardtail.I'm running my fork at 150 currently, but rebuilding it this winter and debating between setting it at 140 or 130. I'm sure 140 would be good and get me a slightly steeper HA, but for all the XC trails around me I wouldn't mind the steepening it by going to 130. I'm just worried the bottom bracket will be too low. Anyone have any experience running 140 or 130?
