The beehive springs weigh 77 grams and the retainers weigh 8.8 grams. The double spring we started with weighs 115 grams and the retainer weighs 31.6. The double springs lived about 80 passes( less than 1 year) and the beehive springs after 5 years have lost 3 lbs on the seat and 2 lbs on the nose. I run the Pac beehive springs. She makes around 2 to 3 hundred passes a year. here is a vid of her making a pass
