THAT'S FAST!!
Some folks will feel more comfortable, and ride
more efficiently, at low cadence, some will prefer
high cadence. Also, road racing is not the same
as tooling around town, and the two will have different
optimum techniques including cadence.
I personally feel comfortable riding any cadence
between 50 and 110 or so, with my usual preference
around 80.

well there are a lot of reasons for 100 rpm as an optimum, they relate to body physiology, efficiency, and history. Cadence for cyclists relates closely to walking pace in terms of human effort. The romans marched their legions on average at 100 paces per minute, and up to 120 paces per minute for attack marches ...see this quote "The soldier’s step (gradus) was two and a half Roman feet long (the Roman foot was .9 of ours). The Romans marched about as quickly as our modern day armies: their route step has been estimated at 100/minute; their quick step has been estimated at 120/minute. The pace (passus) was two steps from right heel to right heel."
I have spoken with former European pro riders and been coached by several on cadence ...they fully support 100 rpm as a base cadence for training and racing, and a capability to surge to 120 for firm prerssure and above that for attacks....track cadence can easily exceed that and often ranges from 100 to 220 rpm.
I train in the gym on a machine with minimal resistance and spin to 190rpm for sustained bursts of 3-5 minutes, and try to keep an average spin at 125 rpm , so when on the road, 100 is a piece of cake and on the track, subject to gearing, 100-120 plus can be sustained for those hard finish laps over the last 500-750 meters.
Its all about practice and endurance, flexibility and smoothness.
But unless you have the right set up on your bike, you are more likely to be tossed off over 120rpm or bounce so much that you cant keep it up.....
just keep on spinning man !!
