|They fit well, are an interesting ride, but still not sold on it......|
What did I want to find out? Well, I'll list out a few things that have been on my mind concerning the concept overall and these Trailblazer tires specifically.
- Float: 29+ has a decent quality for float- well, at least the 29+ Knards do that well. Do the Trailblazers have a similar quality?
- Stability: Would the B+ tires have lateral stability, or would they slide sideways and be hard to control?
- Would this set up be suitable for a long, gravel/backroad event?
- Is the bottom bracket too low with this wheel system?

The Trailblazer has a rather flattish crown to the tread area whereas the Knard is very rounded, almost a "peaked C shaped" crown to the tread. The difference in how they track through mud is noticeable. The Trailblazer sort of "sucks" the center part of whatever soft surface it is covering and tries to pull it up as the tire rotates off the soil or snow. Note the area I have highlighted with the red arrows to the left. If you click on the image, you can get a larger image to see this more clearly.
While the Trailblazer "cut" into the soil maybe more than a Knard does, it also adhered to the slippery surfaces better and did not demonstrate such a tendency to want to lose lateral stability. So, at least in saturated soils or wet snow, you might see a better grip and handling, to a degree, which could make for a better experience.
Stability is better, but float is not quite as nice as 29+ Knards. The last two questions I will have to wait for answers to until I get a lot more riding time on this set up. I have a plan for what this might get used for now as well, but that announcement will be on hold for a bit until I have a few things confirmed.
