Stay angle

OK, so I was wondering if Head angle 70°, Seat angle 74° & TT Length 23.8" on a 20" frame, would be a low stay angle or a high stay angle. Also, would it change the stay angle type if the frame was 18"?

Stay angle?Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

Chainstay angle - depends on wheel size and bb height (or drop) as well - 29ers with more drop tend to have lower chainstay angles, 26ers higher. Only rarely I have seen problems when the wrong front mech is chosen (shallower angle mech on a bigger drop frame) ie the cage hitting the stays, but is a lot variation.0

So what would you describe those stats as: low or high chainstay angle?0

Chainstay angle makes no difference to how a bike rides. It's set by BB height, wheel size and chainstay length which are all important characteristics individually.Transition Patrol - viewtopic.php?f=10017&t=130702350

There are not enough stats there to say what your chain stay angle is. Frame size generally makes no difference to this (unless seat angle and BB drop changes).
Also note that chainstay angle is often quoted as from horizontal, rather than interior angle.
But as RM says, when looking at handling, you need to factor in more than this, on it's own it can't give a full picture. Especially when some seat tubes are curved too.0
