MA45B is the first generation endurance compound from Endless. Launched back in 2001 and opened up a whole new market on the racing scene, MA45B might be old but it's still going strong.
Besides sharing all basic qualities of any Endless compound the MA45B is an top-of the line endurance compound developed for sportcars racing and similar. Suitable for all demands, from the heavier production based sportscars all the way to the pure prototypes, the MA45B is used world wide by a number of endurance teams with excellent results. For this compound the wear characteristics are exceptional and well above those for ME20. This makes it suitable for both medium and short distance endurance races (like 6 hour, 12 hour and 24 hour). The initial bite is high, yet the modulation is still excellent. This means a good combination of performance and control is achieved.
