Thanks guys, I tried to get the adapter off the Airshot but wouldn’t budge even with two sets of pliers, got it eventually but had taken the core out earlier, I’ll know for next time.
Love it, brilliant bit of kit – just wish it was a different shape so it wouldn’t fall over all the time!
Wouldn’t have been able to get it working without one though, so very happy.
Standard rim, not drilled (really should, I can see that now), no soapy water needed. I was a bit worried that it wouldn’t work with my tyres but seems to have worked just fine, will see if it’s still holding up in the morning I guess. Have only done the front so will have to try to borrow a drill from someone at work before doing the rear (may well redo the front too).
Anyone in doubt – get one.
