Title: Rolling resistance in Grass and overall weight (Tuffy vs Black Max)
Post by: LSaupe on May 07, 2018, 05:55:25 AM

Has anyone done a weight comparison (wheels, tires and brakes) between the Tuffy build and the XL Black Max build?

Also, is there a noticeable rolling resistance difference in grass between the two?  Almost would think the advantage to both might go to the large diameter Tuffy.

Any thoughts?

These wheels weigh 4.97 & 4.91 lbs. as shown. That includes Tuff-wheel, tire, tube, bearing set, disk, hub set & bolts.

I think I read somewhere that the Black Max set with tires weighs around 7 lbs each. Maybe more, maybe less. And I don't know if that includes brakes. But this is just hearsay from a fading memory.
