Ok - After having those bright red Tannus solid tires staring at me for almost a month, I was finally able to do some good comparison testing with them this morning at my "super secret test facility" ! Basic Tannus info: I purchased mine from of all places: "Metro Gnome Music & Cycle To Go": http://www.cycletogo.com/accessories-parts/tannus-no-flat-bicycle-tires/ For road bikes you will want the "Musai Aither 1.1 Road Bike Tires". They are about $65, so pretty comparable with a set of: Conti4000sII, or GatorSkin and a latex tube. They are guaranteed for 2 years or 5000 miles. They are only available in 700x28 and 700x23 sizes for road bikes. It will really depend on the interior rim width you have. That is also the deciding factor for what size "pins" you need. The 700x28 , look and feel pretty much like a 600x25 road tire pumped to about 100psi. It does fit fine on the Vendetta. The installation was easy once I used the correct size pins. (I tried a larger ones first, but they wer too wide for my rim to snap in, so it was frustrating and I wasted significant time) Once I used the next size down, it was a cinch! You basically just stick the correct sized pins into the little holes molded into the rim side of the tire. There are about 40 or so per tire. Then you make sure the far side is firmly under the rim edge and then push down and into the pin on the other side until it snaps in place. You then just work your way around the tire until they are all snapped in place. Hint: Try and snap the pins in place on their own a few times before you stick them in the tires and try it. That way you will know which size works or doesn't. ... Bottom line: Running 700x28 on my aluminum rimmed -60mm CF fairiing'd wheelset cost me between 3.75 and 3.92 mph! WOW! Below is my spreadsheet showing what wheels and tires I tested against. Most interesting observations on my part: They come in cool colors - but the red does not match my V20. The feel was very good on the track - even when corning at 24mph. (I have not tried them in wet conditions, but I would not normally ride outdoors when raining unless surprised) When researching these tires I ran across a web-site that claimed a loss of only 1 kph for the tires. Well, I was hoping for that, but....NOT. Maybe they tested the 700x23 (which are likely to be lighter), but the 700x28 cost me almost 4mph. (I guess I will have to try a set of 700x23 also just to see.) Since I really only care about how many watts I am pushing when training, this loss of speed is not an issue and is acceptable at this point in the game. The main point when getting these tires was to not have to worry about flatting and especially sliding out on my left rear again. Enjoy consuming the data: Here is a tire before the pins are snapped in place Here is their Tool (and some un-used pins) you get to help you snap them in place Here is the set on the V20. They don't clash too bad.
