Bucky, this morning’s commute highlighted a significant difference of opinion in the peloton around a topic most of us take for granted; consequently can I request you schedule a training course at the ManCave at the earliest opportunity. I’d suggest setting aside a full afternoon for this one.
The topic: Whether the presta valve needs to be placed in the open position before engaging a C02 canister for the purposes of inflation.
Proponents of the two schools of thought are best summarised as:
(i) those in the picture below, and
(ii) those who think it quite obvious that the valve should be placed in the open position before applying such canister.
You may want to ask participants to bring with them their own supply of canisters for testing purposes.
