I've searched around and haven't seen this question posed.

As a money-saving tactic, I've got an old SRAM rival double running a tripleizer chainring. It works are rides well.

However I'm considering using the crankset on a bike tour. Would you be confident using the granny gear on a tripleizer chainring, assuming a 3+ month tour - with hills and an extra 25-30lb of gear?

Thanks everybody.
