That's what I thought, I'm just not sure if I'll feel the difference in frame size, not sure if the bike will feel smaller.
Even if I do feel a difference, it may be because I'll be going from a 2013 Six-Series to a 2021 SLR.
Because of the endurance geometry & relatively long wheelbase, I don't think that I'll get toe-overlap.
I should add that I use a 100mm stem on the 2013.
Thanks for the input
