Däckproffsen in Växjö (Sweden) is specialized in race tires and studs. They are are contracted by Michelin and have been in the race industry for many years.
For my winter riding they have made a prototype tire for my bike. It is a pair of Michelin Anakee Wild with street legal studs. This makes it possible for me to ride almost the whole winter in Sweden.
Däckproffsen is owned by the brothers Thomas and Mats Carlsson. Their knowledge on race tires and especially in winter conditions is second to none.
