Last fall, I bought a
TMT4 from Kaurit Moto in Estonia.
A very impressive tool. I have friends using the well proven
Rabaconda and I also own another, simpler variant, but for my use, the TMT4 is the one I prefer.
It is very well designed and (nice at my age) provides a working height that means that I don't have to work on the floor to change tires anymore.
It is mainly presented as a mousse changer, but I use it with mousses, tubes and the
T-lock system. It works very well for all kinds. It is adjustable regarding tire size, and can be used all the way down to 10". However, I have only used it with 18, 19 and 21" rims so far.
I think I have changed 10-15 tires on it so far, and am very pleased.
Kaurit Moto has a set of videos,
here is one that shows TMT4 in use
