Okay so on my new used leader my tire and tube were slashed, the front tire. So I grabbed my front alex r500 off my madison and threw it on there. Its amazing the ride quality difference even with the stock $10 25c kenda tires. Im adverging 5-10 mphs higher and climbing 10x easier and just flying way faster then with the deep v on there. Is it the weight difference of having a lighter rim on the front. Is it the 95 air pressure vs the 130 on the rubino pros. Or do you think the hub on the deep v is ****ed? Either way i am completely happy with having my tire slashed lol. It doesnt matter to me either way but im just curious as to why the DRASTIC change.
