Never really had an issue before, normal descending speed would be in the 70kmh mark but yesterday was descending at just over 80kmh, unfamiliar corner came up and had to brake a little to ensure I was going to get around it, this seemed to setup a brown short moment of front wheel shimmying and required me to stop braking and go wide and onto the otherside of the road while feathering the brakes.
WHY did I get the shimmy too much weight on the front caused by not shoving myself back on the saddle? too low on the bars and not enough control? really would not like to repeat that moment again.
Really lucky that I had no traffic coming on the other side, dont mind the crashing into barriers and hitting the ditch, part of the calculated risk you take when racing and trying to make time on the descent, but into a car is NO FUN AT ALL.

P.S telling me to go slower is not an answer that I am racing and just need to know how to minimise the risk of the shimmy.
