Thanks for the ideas.

I looked at the last three flats and all were on the inside of the tube, near where the rim tape is. I checked the wheel and rim tape but see nothing to indicate a problem. Added a second layer of rim tape.

When reinstalling the wheel I noticed that the rear wheel is very slightly out of spoke alignment although I'm not sure if this could be a contributing factor. I'll take it to get re-trued today.

On PSI, have been running the same pretty consistently for a year but will up the pressure to see if that makes a difference.

Running 25's but don't think wheel and bike will support wider without changing the wheels themselves.

Thanks, all.
