My rear tube’s got a slow puncture.

It takes about 3 days to go down to a pressure that’s too soft to ride (when it’s stored in the garage).

Have checked the tube under water and can’t find a leak.

Valve appears to be sound,.

It’s starting to really really P me off. 👿

Just thought I’d share.

I’d say it’d cost approximately £3.99 to cure your pissed off-ness 😀

… and about 5 mins of your time!

I know a new tube is the answer but it’s got past the stage where I can do that….it’s become personal 🙂

I seem to have the same problem on my new tube. I could just replace the tube…

..or spend hours trying to seat the tubeless tyres only to be explosively spattered by “whale sperm”

Sorry old chap, you’re going to lose this battle. Malevolent little bastards they are, inner tubes

I had one on my sons 24 inch front. Took a week to go down.

Fill the bath with warm water. Pump the tube up lots, immerse in bath and watch for a long time until you spot the bubble. Mark hole.

Have bath and cup of tea smiling quietly to yourself.

I am going to differ, and state the slow puncture on my tubeless front ADvantage has done me a favour and made me experiment with lower pressures! Gone 10psi lower as a result.
