Hi Phil, I was in the same boat as you a little over a year ago. My first love is (and will always be) cycling (with Cossies 2nd of course!). Over 20 years ago, I owned a Ciocc Mockba and then a Colnago Master and then a Look KG86, which was one of the very 1st carbon bicycles produced.. and was CRAP! lol
I raced and lived bikes, until I discovered .. cars!
Anyways a little of a year ago I got back into riding and bought a nice Cinelli carbon frame and built it up with some sexy Campy gear. I've taken it away with me to Queensland and have done rides in the Hunter, Newcastle, Central Coast as well as my local haunts between Parramatta and Mosman.
The main challenge is that traffic in the past 20 years has increase ten fold and I actually try to map out my ride on google maps or drive in the car to check out any potential danger points. Having said that, there are some good bike paths in Sydney now and you don't have to worry about traffic but the problem is 4 year olds on training wheels on the weekends!
I've done the Syd to Gong three times a fair few years ago, and they used to ride through the national park. Not good for skinny road tyres and for me, detracted from the ride. Not sure if its the case these days.
So anyways, I could go on forever so here's my bicycle version of a cossie.. er make that a Ferrari
and yes, you can buy a brand new car for how much its worth
