Long stem influence on cyclocross handling I want to introduce myself to the cyclocross world, I'm looking for my first bicycle. I found a great used bike with a frame at size 54 (54 seat tube x 54,5 top tube), which would be slightly small for me(1.86 m tall). 
On my road bike I use a frame in size 56 (54 seat tube x 56,5 top tube) with a 130mm stem, it has the perfect fit.

In my research I saw that cyclocross bikes need to be 1cm to 2cm shorter in full reach, which would allow me to continue using a 130mm stem, but would using such a long stem in a smaller frame affect the handling of cyclocross specificities(bunny hops, short and steep climbs/descends, 180º turns)?
Couple of problems I can think of:

Reduced front-center (BB to front axle) on the smaller frame which means more toe overlap. 

For the same reason the front wheel will be tucked further under your center of mass, which may create problems on steep descents.
