The “VarioLever” makes it possible to brake using only two or three fingers without pinching the other fingers. Of course, when the lever is completely extended (roughly corresponding to the length of the original lever) it is possible to brake with all four fingers again.
Another innovation is the easy adjustability of the lever reach, which can easily be applied whilst riding – important to compensate for brake fade (e.g. at high load, fast mountain bends). In addition, the reach can be changed to bring the lever closer to the handlebar, making it easier to reach. This is made possible by a large rotating adjuster that can easily be operated even when wearing thick gloves.
The extraordinarily intricate construction is also extremely robust. Made from strong aluminium (AL 7075 T6), the preferred type for aerospace applications. Anodised. ABE approved, no need for entry in the log book.
The original lever attachment is retained, which makes this very easy to fit to the bike.
