Yeah I’ve always been confused about whether you’re supposed to finish at the valve or 90 degrees from the valve or opposite the valve. :shrug: I finish away from the valve but I also don’t use TL.

The “slack” thing is something a guy from Mavic showed me when I was demoing UST at Sea Otter. It definitely helps a LOT. Maybe I’ll make a video if this doesn’t make sense. But here I go:

Get the tire to the point where there’s only that one finishing edge left. Turn the wheel so that that edge is towards the ground. Put the wheel on the ground (ideally a soft surface). The goal now is to stretch the tire along the circumference of the wheel towards the finishing edge. So if the finishing edge is at 6 o clock, start pulling the slack out from the 12 o clock position with both hands in opposite directions. Eventually your hands will be at 3 and 9. At this point, you can use your entire body weight to pull (push?) the tire towards the finishing edge. Continue to slide your hands towards the finishing edge while maintaining tension. Without releasing tension, try to get the finishing edge over.
