How are the Stone 2x chainrings? Like if you're spinning slowly does it consistently hook onto the first shift pin available and shift up, as stock Shimano does? And shifts under heavier loads, cross chains in the big ring acceptably, etc?

Hello, the photos of the Eglath frame are misleading. Indeed, the frame is very inclined. The head tube is very high (opposite of the Vanyar) and the seat tube is low. In the photos, it appears that the horizontal tube is parallel to the ground. For example, if I follow Elves' size recommendations, for my 1m78, I end up with 120mm of head tube for the Vanyar and 170mm for the Eglath.
