hobbyhoarder on October 4, 2024 8:27 pm Yeah, it’s not 100% air tight. You’re supposed to take out the tube though if you’re looking where exactly the leak is.
Qualabel on October 4, 2024 8:36 pm I need to inflate my tyres every fortnight. It makes a big difference to speed and grip.
catlips on October 4, 2024 8:37 pm No. You have a leaky valve. It can be replaced with a new one without removing the tube. Cap or not, it will slowly lose pressure.
phamstagram360 on October 4, 2024 8:44 pm look up this [https://en.wikipedia.org/wiki/Schrader_valve](https://en.wikipedia.org/wiki/Schrader_valve) you need a new metal inner part.. easy fix… or just tighten your metal inner with a Schrader valve tool.. most bike store will help you…
HaziHasi on October 4, 2024 9:11 pm that looks like a leaky valve. take the tube out, test it again to conform the hypothesis and get a new tube. voila, problem solved 🙂

I think that’s a leaky valve, and you need a new inner.
