Envy Reaper bars are aluminum, so the only way to run those are with IHC, ICS, or fullsize SCS. I don't recommend ICS as it is a pain. IHC works great, but you'd need to get a new IHC fork. You could probably use your standard oversized diameter clamp from your current setup. Alternately, you could use the fork you have with aluminum bars, but you'd have to run a fullsize SCS clamp (not a baby SCS).
