I haven't found one yet.

Reallly slow and heavy even at 50-60 PSI.

I have the 2.15 Performance Line version. Schwalbe sais they weigh 710g but mine are 780g.
I really don't see how these tires have such good reviews.
They were supposed to be fast and comfortable. When inflated to minimum pressure(2 BAR) they are comfortable but sooo slooow. When inflated to max pressure, they are a little faster but the comfort is gone.
My Conti X-King 2.2 tyres are faster and more comfortable at any pressure.
I am really dissapointed.

rides smooth. good sidewall, overall comfort, build quality

cost, but on par with other tires, maybe a little heavy. but probly cant have strangth and light weight

ive had this tire on my 29er for a few months now and they have been great. over all ride is great at almost full psi, build quality is very good. ive ran over some crazy stuff on the street and they hold up. good contact patch for street use. smooth ride and very predictable in most weather conditions. i have not used them in rain, but im sur ethey would be fine. for a street tire i think you wont find a much better tire.
