from the velo::re website:
“Beltoe and Beltie are belts made from recycled bicycle tyres. Each one is an individual, and handmade, with its own history. The tread bears the scars of every mile travelled, and every unauthorised skid. We like the idea of recycling and making full use of the discarded and the superfluous, ending up with something that already has its own character.
Belties are made from front tyres, which get less wear, so still have plenty of tread left. Beltoes are made from back tyres, which work harder and carry more weight, so they`re kinda threadbare.”
