I’m trying to decide between a couple of frame sizes for a build (based on an On One Inbred) or a complete bike purchase (Carrera Vulcan)
One thing that worries me about the potential build is my inside leg measurement is spot on the frame size change (34″ is the longest leg for the 18″ and the shortest leg for the 20″ frame).
As my back is fused due to an operation to correct scoliosis I cannot ‘hunch’ or curve my back at all so I suspect I need a ‘longer’ frame which logically points me towards the larger frame, but I can’t try one out
At least with the Carerra I can sit on it in the shop and see how it feels.
I think I would get a better bike by building my own and a neighbor has all the tools and experience of bike building and maintenance to help me out, but can’t help me with this question
Anyone any experience of this type of thing or can anyone direct me towards a ‘simple’ guide to frame geometry that might allow me to access the frame suitability for ‘upper body size’?
PS – I am too far from the On One shop to pop in and chat/check one out 🙁
