I've gone months without having a flat then the other day on my training ride i must have been day dreaming and rolled over something, jolted me out of my dreamstate and there you go, flat tire. That i'm ok with, i felt something that was the cause.
So i fix it, hobble home.
Next day, different route, no flat, great ride.

Next day, different route again, out in the sticks and for some unknown reason, bam another flat (always the rear).
So i fix it and limp home again. So that afternoon i'm getting my bike and gear for the next early morning ride and i notice my tyre is flat? WTF??

So i change it out again with a brand new continental tube. This time though i gave the tire a really good inspection, sure it has a few cuts and slits over it but for the life of me i couldn't find any signs of glass or wire or any other foreign object in it. I did notice that my rim tape was sort of heavily "moulded" into the spoke nipple holes. ie the tape wasn't especially smooth, you could easily feel the indentations where the spokes are. could this be a possible cause? is the inner rim meant to be completely smooth?

so i ponder this again this morning on the way to work and you guessed it, another flat. at this stage i'm hot and sweaty on the side of a wet muddy road trying to change my tire again just having a really bad morning (bear in mind this is my first day back to work after 12 days off). I do recall being forced to ride through some glass this morning though as i had a car in my lane and no where to go so that "could" account for it.
As i sat at my desk this morning repairing the tube it was only a simple pin hole puncture on the outside of the tube, consistant with a typical debris type flat.

Am i just being shat on my the flat gods and this is all just bad luck? what else can i do to check if i have any debris in my tyre or is the rim tape a possible cause? I'm running pretty new Rubinos, they are 60tpi.

In any case i'm taking my new Rubino pros (120tpi) off my Colnago race bike and putting them on and will also get some new rim tape from LBS today just to be sure.

Any other advice suggestions?
