Heck yes. I took my FG on my training route when my geared rode bike was in the shop. During one downhill I hit 32.5 mph with 42X16 gearing. I plugged that into a cadence calculator and came up with 150 ish rpm.
However, I only managed it for 20 secs before my legs felt like they were going to fall off.
No way would I ever try that on platforms.
