They feel Good...
I like the feel of these tubes and yes time will tell if they are the business. I replaced my original tubes after 2 years because i fill them with slime which goes hard after this time. My original tubes hit a puncture early on but the slime sealed the problem. I did not trust the source of my original purchase so i swapped onto these tubes which so far is good and doing the job so i am very happy and long may it continue. I may have been unlucky with the original and we know the danger of punctures but my mind works on gut feelings and my gut instincts tell me that the swap over to these is a good decision so here we go with them...
