Jim Mwrote a review of Schwalbe Racing Ralph Tire -29in on March 27, 2016
Familiarity: I've used it several times
Currently running Racing Ralph or Rocket Ron on the back of an Air 9 Carbon depending on the conditions. It is a race/race prep only bike so I was running the Lite Skin. Great grip. Very confidence inspiring until the 2 hour walk out of the dark woods because of a side wall cut that could not be repaired (and of course everything was hosed down with sealant). Switching to the Snake Skin on the unsprung rear where it takes more of a beating. Just too easy to cut the Lite Skin. Keeping the Lite Skin on the front.
