It seems your M Look is near in between a Time small and medium.

I’ve had Looks and a Time, both terrific bikes.

So if I’m using the look with a 120mm stem

Should I go for M vxr? And run with a shorter stem?

which model and year?

The chart you posted is from several models back, are you certain its the correct geometry chart for the bike you are considering?

I like a long, low set-up and ride a medium ZXRS with a 120 stem...I am 5'9'' and run a saddle height of 28 inches (center of bb to top saddle), if that info is helpful

Sorry, missed that detail above...

I'd be concerned that the headtube difference between small and medium would result in too much drop even if the reach were in an acceptable range

Can you mock up the fit (stack/reach) of the TIME using your LOOK?

clearly in-between sizes

First a disclaimer...I am no expert. The reach on the size S TIME is closer to the LOOK but the stack is significantly less. If you wanted the same fit, you'd need to add (at least) 25mm of spacers to the size small TIME to approximate the taller head tube on the LOOK.

Since your LOOK has a tall headtube, I am assuming you prefer a 'endurance fit' over a 'racy fit'? That assumption suggests the Medium would be a better choice. However, the difference in reach between the M TIME and LOOK is nearly 30mm. A 90mm stem (assuming same bars) to get to the same position might make for a twitchy feel? Perhaps others can chime in?

Finally, I am a bit confused by the mock-up as the horizontal top tube measurement and headtube size don't match any of the frame sizes?

The spacers gap is due to the headset cap

I’m running a -12, 120mm stem, slightly different from the diagram I attached sorry
