Ooooo it's a tire recommendation pile-on....
Haven't been super happy with anything yet for Calabogie, so going to try (paste clip) Mitas C-19 Eagle Green Super Light Extreme Front Tire 90/90-21 ....good for wet rocks to medium soft terrain, 3 ply super tacky compound, supposed to be a well liked tire in Europe.
Guys also run Bridgestone M59s, Michelin S12 XCs, Shinko offers a GoldenTyre clone called the MX216 which seems to be getting some love and are much cheaper than the GoldenTyres.
