Summit1 and summit 2 valve adapters in IKs...
I recently discovered that you can easily use a summit 1 valve adapter to inflate through a summit 2 valve. The only difference in structure that I could find was that the summit 1 adapter had a wider orifce than the summit 2 which let it slide into the S 2 valve but would not work the other way round, ie using the S 2 adapter on a summit 1 valve. Also the cover of the S2 valve is identical to the S1 adapter.
Anyone else have the same finding?
