The men had seemed friendly, chatting with staff, Mrs Sargent said. It was not until after they left that staff discovered about $150 worth of goods, including gloves, grips and goggles, had been taken.
There was an element of "name and shame" in using social media, Mrs Sargent said.
"We want to get it out there that we are not an easy target. If you are going to do it, that is what is going to happen.
"The shaming part of it may potentially stop [thieves] from doing it in the future."
Small businesses like theirs could not afford to ignore shoplifting, Mrs Sargent said.
"It's the principle of it. If you get somebody doing that once a week it adds up over the year. We are a family-run business - we are not a massive corporate business.
"We can't afford to take losses like that all the time," she said.
The names of the two men, as provided by the Facebook community, have since been passed on to police.
