Groupset

Shimano Tiagra

Shimano Tiagra is an intuitive groupset for the versatile rider. Not only is Tiagra performance strong, it is also incredibly easy to live with and requires minimal maintenance. Whether you commute or do road riding in your spare time, Tiagra can handle everything at a high level.

Tires

Panaracer GravelKing SK

Panaracer GravelKing SK is made for speed on even the roughest of terrains. A combination of an aggressive tread, natural rubber compound and puncture resistance create the base for a high quality tire.
