I come looking for advice on finding a bike for my dad. He is a rather tall man and not all that flexible so finding the adequate gravel bike is no easy task.
He needs something with ~390mm reach and ~650mm stack.
Does he want drop bars? The Salsa Vaya is close-stack is slightly lower but reach is spot on in the largest size. https://salsacycles.com/bikes/vaya/2020_vaya_grx_600 If he wants upright bars, I'd look for a hybrid. They make great upright gravel bikes.
The Felt Broam has a high stack/reach ratio. Check out https://bikeinsights.com/. It lists the geometry of nearly every bike. I'm a stiff old man with long legs and ride the Broam's precursor, the Felt V-85. Not upright like a hybrid but more so than most drop bar bikes. Also, check out stem risers and/or a stem with an upward angle. I use both because I bought a 58 cm frame because I wanted a shorter top tube but needed the height of a 61+. The modifications made a huge difference in comfort.
