New bow-tie tire!!!

[Scott711]

My sprottraxx have held up good for romping around the neighborhood and have good traction but I've noticed since going with the 8XL and lipos that on speed runs they elongate a bit. I've only run the with 14/51 so I can imagine how they might stretch going to taller gearing. I blame it on the heavier ramped nobs in the middle. I'd like to try a 40 series step pin for looser conditions but I don't think they make that in a 40.
