Last year I laced Champion double-butted spokes to WTB ChrisCross rims. I was a bit skeptical about my purchase at first because the rims are described as hybrids; they can used with tubes or without. But they were light and stiff and I liked the way they looked. I chose to use tubes and it's resulted in numerous flats - likely due to the rim tape moving and exposing the seated nips to the inflated tube (see image). At least that's my thinking given where the tubes punctures are.
As you can see from the photo, the rim itself features a deep groove into which the rim tape fits. Yet somehow the tape manages to shift, causing punctures. FWIW, I'm running Panaracer Messengers (28s). And I don't always use a 28 tube; sometimes I use a 23/25. Any suggestions on getting the rim tape to stay put are most appreciated.
