V=2017 (and possibly earlier) Vipec arm
T=2018 Tecton arm
---------------- Bare arm -------------- Fully -------------- Tips at
---------------- (tip to tip) ----------- Deployed ---------Topsheet
90 V ------------- 135 ------------------ 110 ------------------- 91 -----
100 V ------------ 152 ----------------- 122 ----------------- 102 -----
110 V* ------------ 157 ----------------- 130 ----------------- 108 -----
120 T ------------ 170 ------------------ 147 ----------------- 130 -----
* This pair was purchased separately and the package was labeled "115 Vipec", which is obviously way off.
As you can see, not a big jump from 100mm to 110mm 2017 Vipec brakes, but a huge jump from 110 Vipec brakes to 120 Tecton brakes.
Interestingly, the 110 and 120 brakes are the same from the middle to the first bend, and a more shallow bend angle (followed by a tighter outer bend) is what makes the 120 wider. Adjusting the ~45 degree bend angles in a vise should be a lot easier than modifying alpine brakes with 90 degree bends, since you can play with minor changes to the two existing bends instead of completely relocating full 90 degree bends.
