Sure, we can speculate all we want. They might as well put these basic facts up on the website
The max tire pressure for the hookless Enve 4.5 is 80PSI @ 27mm. The max pressure for this Vanquish line for 28mm is even lower. 70PSI. Not optimal - maximum. Why do they have a lower max pressure than many hookless rims?
Curious to know, for safety and performance reasons, why.
Apparently 75PSI max for 25mm on those too now. For a 240lb person -max pressure 75PSI.
This doesn't sound great vs. @marcag's and others finding that for 25mm tires, the optimal pressure for World Tour Riders is higher than 80PSI...for guys way, way under 240lb.
Now if they're just moving to the @Slowman theory that 23/25mm is done, and life starts at 28mm now...maybe that makes sense. Except HED showed 25mm results for their new Vanquish aero charts....and they were faster than the results for 28mm.
