What was your dream bike thread?
Discussion
The year was 1999 if memory serves correctly and was watching as much Ch4 (didn't have Sky back then) extreme sports on weekend mornings as I could whilst taping it and watching again during the week. The Rob Warner / Crawford Carrick Anderson days.
This was my dream bike...
One day, I would like to find a good example of the ATX 1 frame and build a replica but for now I don't mind living the nostalgic dream!
What would be yours...

For the Cannondale it was to do with gear ratios and optimum chain ring sizes
"Cannondale's engineers optimised the linkage to work with a specific chairing size, a larger or smaller ring would affect the performance, but their racers still wanted to be able to change their gear ratios to suit different courses, so this system was developed to keep that size constant.
There are five rings in all, but it is the ring on the non-drive side crank that drives the system, in the same way that the chainring(s) do on the bike sitting there in your garage. That power is then transferred by the first chain up to the sprocket sitting forwards and above it. A fixed axle transfers that power through to the sprocket on the driveside and a chain connects that to another sprocket sitting behind the larger driveside chainring. There is then a system similar to a freehub engagement to turn the main chainring as it is not directly attached to the crank arm. To adjust the gear ratios the team mechanics could change the size of those four sprockets driving the chainring - although it wasn't too popular with them as it was so complicated."

Glad to see my old thread resurrected!
Even better, someone who posted actually getting the bike of their dreams. I had a chance of getting the Giant ATX 1 on two occasions now. One had a different frame configuration to the DH bikes and the other the guy was taking the pi55 with what he wanted to sell it for!
