DMR Bikes base resides deep within the cold wet muddy murky forest's of the United Kingdom.

Riding our trails involves, dirt, rocks, slate, wet roots, clay and sandy soil.

Mix this together and you brew a soup which will grind your gears and break their teeth.

We needed chainrings capable of surviving our terrain. Selfishly, we made them for us and you.

Chainrings tested in the harshest of UK weather.
