FERN BICYCLES AND ALLYGN COMPONENTS THE THREAD THAT CONNECTS US
First came
the bicycle.
In 2012, I started handbuilding custom steel frames for fast touring and randonneuring. Those bicycles became FERN.
Then came the questions: “Can I buy that rack for my bike?” ALLYGN grew from the parts I developed for those individual builds — and the idea of sharing them with more riders and fellow framebuilders.
