Correction – the seat post size is 30.9mm, not 31.6mm. Still dropper compatible.
68 degree head angle (on sagged 140mm fork), 74 degree seat angle. No big departure from the original Alpines, just a bit roomier in the top tube and tad lower BB as those were the only criticisms levelled at previous versions. I didn’t want to change stuff for the sake of it.
Graphics on the production frame will also be different as the reflective panel sticker gets a mixed reception. The brushed aluminium ones I use on my other company’s frames (Factory Team Bikes) would probably go well with the Alpine’s raw look.
