My lifetime learning style is to make mistakes and learn from them. I try not to have confirmation bias, where I make a choice, then bend over backwards justifying that it's better choice to make myself feel better about it. Granted, I've only had 3 test rides on the new rear tire. On the 2nd and 3rd rides, I adjusted the air pressure down to 30lbs from 38lbs originally, and the tire felt better. I'm also scuffing off the surface rubber in these first rides and I could see that maybe they might be impregnated with some sort of mold release agent which needs to scrub off. (or maybe not)
I bought the battlax based on my impression from reading comments here that it was "just as good" as the Avon RR performance. So far, that's not the case. If I had to do it again, I would have bought the Avon, at the higher price and accepted that it's going to wear out in 2 season's worth of riding. It's not that I ride around dragging my knees or wear some armored race suit and ride to the limits of my tire performance. It was just incredibly reassuring to lay the bike into a turn knowing the tires had more ability to stick than I would ever use. So far, I don't feel that "YET" with the Battlax... but time will tell
The 110/90/18 battlax measure 4.25" wide mounted on a 2.15 rim. I think the same Avon RR tire measured close to 4.675". The battlax is visibily smaller on the bike than the Avon of the same size.
I bought the battlax based on 2 things. One was the Battlax is a dedicated rear tire, so it has more tread depth, and two was that I got the impression that they are "as good as" the Avon RR, based on my interpretation of the many comments I read here. So,... there it is... Once you ride on sticky tires, you gain a lot of confidence in laying into corners, and any tire with less grip instantly makes you wonder if you will reach that tire's limit or figure it out before you reach your own limit first... which is the worst possible scenario...
