Still got that email from Enve? I'd be curious to see it.
I'm a stickler for typos, but no one gets fired for them. Yes, they had a lot of stuff going on, maybe something slipped through.
What measurement do you propose be used? That's not for strength, by the way - even remotely. It's a reflection of the balance they sought between stiffness and compliance. "Too stiff", "Too flexy", and "Just right" make perfect sense to me. If they had inserted a unit instead, first, it would be utter bullshit, and second, there's nothing to compare it to, because other wheel manufacturers also don't include a unit of strength in measurement of their wheels. So...just looking for holes to poke, or what?
