I’ve been riding ProCore and MM Super Gravity tyres for years and it has been magic, pardon the pun.
Recently bought some cush core but have yet to install it as I am experimenting with a Double Down Assegai on the front with no insert at the moment. So far so good as the grip of the Assegai is insane.
The Super Gravity Tyres are a great weight for serious performance option in my opinion.
My only gripe with ProCore was the valve which can get guncked up with sealant over time and require a disassemble and clean.
Weight appears to be pretty much the same between the two so let’s see what the performance is like when I finally get to installing it.
Note: DD Assegai with no pro core and MM with pro core is about the same weight, so that is why I am trying without insert on the front. The DD Assegai is very heavy, but damn it grips!
