Iv'e just fitted Armadilos on the front & rear they seem OK but as you say ,time will tell!! They do ride a bit hard till you get used to them , compared to the gatorskin I had (only lasted 3months ) Useless as punture proof I ride a steel frame & have a Selle Royal Lookin saddle wich helps take the harshness out of the ride They are 700x23 & I ride them @ 100psi , this seems an ok press. but I may experiment a bit on that I will keep you posted on the success or failure ,but wats next ,solid tyres ???
