But the "New" MTB technology such as 1 1/8" steer tubes is also becoming Road Bike Standard.

There is a good number of road bike (commuters) that use "MTB" cleated shoes.

I'll tell you, walking up marble starways wearing leather soled shoes with plastic cleats and no heals was.... interesting...

Anything else spilling back from MTBs to Road?

Rohloff????

Oh... that reminds me, time to build up my dynamo wheel

Those old cannister generators were a pain
