Put some new pads on the rear of the commuter's XT Canti brakes - worn out in two months of wet commuting. Front are OK.
Guess what got worked on today?<snip> When done, this will become a flat bar with a SRAM 11 speed 1x drivetrain replacing the 8 speed triple.

I have had that problem. The cause was very obvious because the hole in the tube was at the bottom of the valve.My son had a puncture on his Gary Fisher. I patched it, the tire was down again next day. I bought a new inner tube with sealant, and also took a very close look at the tire, to prevent reoccurrence. Nothing! I then noticed that the valve hole has very sharp edges. I guess someone converted from Presta to Schrader by drilling out the hole and leaving at that. The sharp metal must have torn the valve. I filed down the edges and inserted the tube, it held during the night, so hopefully this one is solved.
