50.01 mph braking instability

[Nigeyy]

Why is it that when I brake from 50.01 mph on a very steep downhill I cant do it with no hands? What I mean is when I DO brake at that speed, my bicycle wobbles all over dramatically when I put my hands behind my head and whistle to the tune of "Oklahoma" (prefer if over West Side Story). Basically my bicycle is extremely unstable at braking on extreme declines. ****in ell!

Have you thought of staring to break at a lower speed? Going downhill I'm usually grabbing lever at about 20mph. I am somewhat heavier and less brave than I was 20 years ago.

What are you talking about, this can't be serious?? 50.01mph???

I'd struggle to control a bike at that speed as I lose balance if I'm going that slow. Stop tottering around and go faster(maybe get out of the granny gears?). No need to brake if you're going fast as everything will move out of your way or you'll just plow through it without noticing it.




Maybe.

Er, *cough* ...

My bike is wobbly between 46 and 52mph - it's to do with the harmonics of the frame and the vibrations created by the wheels being very slightly out of balance. As @0-markymark-0 says, you just need to stop messing about and go faster. I get the same at 92 to 104mph too.

You may have metric brakes, which are incompatible with imperial speeds. Try braking from 80.5kph and see how you get on.

Whistling Dixie might help too

Are you going forwards or backwards? I don't have that issue going backwards, try it. . .

On tarmac, I can see that you might have problems braking at that speed. Best to stick to sheet ice.

I have the exact same problem going uphill...

You need to re-install the brake software including any updates. Alternatively you could switch to Linux brakes, though they do need a bit of initial setting up.

iMac brakes are far superior, when will people realise this

I always prefer to bunnyhop at 50 MPH on hairpin bends. Much smoother experience.

Especially on the fixie.

Don't use your brakes, just drag the heel of your shoes on t he tarmac. Much more efficient!
