Received the unit.
As of now, I do not recommend it if you need to mount tires on wheels that have a shallow drop center such as the rear BST carbon wheel. It may require a learning curve to perfect, but it took 3 men and way too much effort to mount a michelin tire on a rear BST carbon wheel.
For the almost $700 price tag after including the price of shipping and an extra clamp, I expected an easier to use tool even on the most difficult to mount wheels.
Other negatives include the footprint of the device which is significant, and it weighs 100 pounds. When not in use, I disassemble the unit into major substructures so that it does not hog too much garage space.
The rear BST wheel is the worst case scenario for tire mounting since there is no easy way to gain some tire bead slack by positioning it in a deep drop center while working the opposite side tire bead over the wheel rim. This potential issue of difficulty with shallow drop center wheels is mentioned in the installation videos, and they were not kidding.
I will report back after a few more tire changes, but for now, I would recommend going to the shop.
P.S. : Just spoke with the No Mar customer service and they told me that indeed, shallow drop center wheels such as the BST rear make it more difficult to mount a tire. Big time bummer.
