I find a half degree change of HA pretty obvious on a 26 let alone a whole degree on 29
Fair enough, although I notice that when bike mags actually measure angles (rather than just re-printing the press release) they never seem to match up with the spec. I’d love to know what the variance is, but we’re getting off the point.
Going back to the Codeine: if you want a 29er with short stays then something has to give. It might be tight clearances for rear tyres, or the lack of a front derailleur, or just a complicated and expensive frame.
If you can live with longer chainstays then you can have a simple frame with good tyre clearance and the option to run a front derailleur. So, that would be the key question for me “how much do I want the shorter chainstays of the Codeine?”. If I don’t care about short chainstays I’d take the Five, but if I really thought they mattered I wouldn’t.
