47.2 down a bridge with a good tail wind. the road stopped pointing down before the speed stopped going up.

Drag

Greater than 50mph in a paceline of four MTBs on a LONG descent on the road into town from the campground in Estes Park, Colorado, back in '92. Wow. I still remember that. Freakin' scary but sooooo exhilarating! It felt fine up to about 25-30mph beyond which the pucker factor kicked in and exponentially grew from there. We were passing up automotive traffic... the wail of the knobby tires... the sensation of pedaling having zero effect... to slow down you lifted your torso or got out of the slipstream... and every nanosecond you knew that if you miscued a bump, miscalculated an apex, got too close to the wheel in front of you, had your tires wash out, or a dozen other factors... it would be OVER in a big big way. I never bothered to look down at the bike computer on the descent. No way - much too scary. It was only when we slowed into town that we were able to click through and read the max readings. What made it so memorable was the length of the decent. Wow. Good times.

The length doesn't really matter. You will hit your terminal velocity pretty quickly on a steep hill.

He could have. I've gone 56 down the hill from the video I posted in the other thread, and a teammate who has 60 pounds on me flew by like I was standing still. He had gone over 60. Enough weight, steep enough hill, and a good aero tuck is all you need.

Edit: may as well post it here too

So fast I got home before I left.

Mr. Beanz

I love these threads! Riding on the same hills with the same riders on the same rides, I hit 45 and they always manage to hit 60 but I dropped them on the descent! Hmmm!

Drag

UMD -

It's hard to acknowledge how steep that really is until I noted your "% grade" figure overlay (and the MPH reading of course). Again, very cool!

Daytrip

46.8 mph. I have a short, steep hill on my regular ride that routinely gets me over 40. As noted elsewhere, it's a little nerve-wracking, but exhilarating. Mostly, I worry about hitting deer and turkeys. New wheels and better tires have made me feel more confident about the speed, but not about the wildlife.

Dheorl

America does look like fun. All the possibility for speed. Rolling English countryside generally doesn't involve straight roads. I can't go much above 40 on any of the hills around me because of the corners.

I think I'm still young enough to not get scared by speed. You should see me skiing

The fastest you went in that video was 53.2 for a split second, not 56. Mostly 51. Not that that isn't fast, but I thought I would be a stickler.

coasting 

hear hear. the rolling hills are never long enough to build up a decent head of speed. on steep bits i can accelerate up to mid 40s very quickly but by then the downhill has already ended.

Yaniel

he didnt say he went 56 in the video. read it again. i thought i would be a stickler.

Cat4Lifer

I hit just over 50 MPH in my early 20s.
I could have gone a lil' faster, but I got freaked-out and hit the breaks.
I kept my speed at or just shy of 50.

Touche. He said on that hill from that video. Not on that hill during that video. This is why I am a full time engineer and amateur grammar nazi, and not the other way around.

42 mph.

36mph on flat ground, drafting a Mack truck, on a Schwinn World Sport!

Incorrect

Cat4Lifer

no, really...all I needed was the right amount of torque.

Does anyone know if bicycle tires are rated for speed?

caloso

I did the Kessel Run in 3.2 parsecs.

umd

brakes not breaks

Cat4Lifer

hahaha

I hate you now, more than ever

That was for this

Tag, you're it.

chefxian

Yes, but my Tauntan is quicker off the line then your Millennium FAlcon.

I think the fastest I hit was 43-44mph. That was after a nice steel climb and a short downhill... The funnest downhill was after doing an 11 mile climb which took over an hour, then going back down it in five or ten minutes. It wasn't a steep climb so I was able to do about 98% of the descent without touching the brakes. Top speed was only 38mph, but I'd stay there for several minutes.
