Bought a Joe Blow Sport. Check valve started sticking and failing whilst inflating my airshot after about a month. Refund incoming.
What do I replace it with?
1. Under (or around £100)
2. Not including a tubeless inflator (I have one separately and often travel with just road bikes)
3. Suitable for both road and high volume MTB tyres
4. Goddamned hard to break
5. Decent pressure gauge (tho I do have a mini digital d2)
In before take the pump apart and grease / silicone spray the check valve / replace it (I tried all of these!).
Sus rennkompressor, best track pump I’ve used.
Better buy a SKS Renn. Replace head with a Topeak dual head. Enjoy for at least 10 years until you lose it or leave it in the Car Park. I use mine with an Airshot. The same Airshot that blew out the seals of the Topeak Joe Blow I used to use at a much less than indicated suitable pressure. I would buy another Renn(koppressor) tomorrow if I did lose mine.
