I now have a foot in both camps, Vector 3 on my TT and Assioma’s on my road bike. The Assioma’s are so far the best by a long shot. The charging is great, no fiddly battery replacement, the mobile app is faultless and the best thing is the bearings. They spin beautifully, so good it can be a problem clipping in at an intersection if you rush, mis-clip and spin them out. They spin so well! Definately watts saved there for the marginal gainers too.
