+=== 1980 Hakkapeliitta ===
+Nokian Hakkapeliitta tires were the only early supplier of wide 650b & 700c tires good enough for mountain bikes.  Built for Finland's winter ((Even in summer, the average high temperature is only 71 degrees in July in southern [[https://weatherspark.com/y/91636/Average-Weather-in-Espoo-Finland-Year-Round|Finland]])), the Hakkapeliitta is nowadays famous for its studded tires.  In 1970's & 80's they had a summer version without the studs.  More info [[https://www.nokiantires.com/company/hakkapeliitta-80-years/teemat/hakkapeliitta-spirit/|here]].
