On my flexstem I had brahma bars.
150mm long flexstem and bendy bars with about 6 inch extension... by the laws of leverage I probably had about 3 inches of travel and was able exert huge forces on the pivot of the flexstem which eventually led to it's (timely) demise.
52 tooth chainring.
On a hill in the local forest I used to be able to get to 43.5mph on my computer running a 46 x 12 drivetrain. I bought a 52 tooth chainring and headed out to break my record... and failed
When i went back to the 46 tooth because the 52 tooth made the shifting was rubbish I was able to get up to 44mph. The big ring made no difference... 43/44mph was the max you could get out of that hill.
