I'm sorry to rant, I'm usually not this full of crap...but...seeing that this is the second time I thought I'd shoot this out there to see what others' experience have been like. I rode the Argus with my MTB on slicks with Dr Sludge tubes. Last week when I was ready to put my knobblies back on I could deflate one of my tubes as the sludge had clogged the valve. After spending about 20 mins of cursing and fighting I managed to get the air out. Long story short - now I can't inflate the tube as there isn't enough space for the air to go through. This is the second time I have had this problem and thought I'd share my experience. I stored my bike in such a way that the valves were at the top so that the sludge sits at the bottom. Today I couldn't wait anymore and stopped by a shop to pick up tubes, call me a sucker as I walked out with Dr Sludge again...only this time when I opened the packet the sludge had leaked out leaving a rock solid crusted valve that can't move... I'm so disappointed as one tube costs R165!!! I think I'm just going to go back to tubeless...Stans!
