The speedometer system you use can be modified to double the recorded speed by using two magnets instead of one. Also, the footage looks sped up as if the cars are going 80 miles per hour.

53 MPH about 7 years ago on the straight and steep. A cross wind hit me and I was in the other lane before I knew what hit. Now I seldom go above 40.

We once hit 65 on a pass descent on our tandem. Both positions have aero bars. Known 4-lane road, gentle sweepers, good pavement. I don't know whether Stoker had her eyes open or not.

You're funny man. LOL. Conspiracy theories now?? Where is the splice??
This whole video is unedited. The cars go by slower and slower as I go faster. My tires are making a hum from about 21 to 32 mph. You can hear it going on and off 4 times. I can't FAKE that.
At my max speed the motorcycle and black truck go by at 111 mph >> 45.5 + 65.5 approx.
60 mph = 88 feet /sec. So 111 mph = 162.5 ft/ sec.
Divide by 25 ft. for the truck and you get 1/6 of a sec. Compares exactly to the video.
Picking out a speeded up video is fricking EASY. The jiggling cables are what's distorting the view.

For years my top speed was in the high 40s, and I' would always try and break the 50 mph barrier, but I never could.
Now, I don't like going faster than the low 40s.

I remember hitting 44 mph on some descent here in SoCal on a group ride a long time ago. I had been in the area for about three weeks, and had literally no idea where I was. Good thing they didn't drop me! I was on a Dawes Atlantis, which someone once told me was a crit bike, because the steering was so steep. 44 mph was pretty terrifying on that thing. Now I routinely hit mid-30s on my old StumpJumper, and it's pretty cool how stable it feels.

Some of these speeds are wild! According to Garmin, I hit 42.7 mph one time last year.

I know I was a bit faster than years ago while going downhill when I couldn't make a turn and went off the road into some woods. (I wasn't even tucked in for speed. Just didn't realize how fast I was going and couldn't brake in time.) Since then, I'm very hesitant to go any faster than mid 30s. Start getting nervous after that.

According to Strava, I routinely hit the mid 40 mph range going down a fast sweeper on 9W heading northbound, right after crossing the NJ/NY border. In my mind, it's actually safer to get into the 40s there. You can never tell what kind of crap you'll get on the shoulder (gravel, broken glass), so if you're carrying any speed going into the descent, you'll have more reliable traction in the vehicle lane, which has a speed limit of 45mph. If I'm traveling in the car lane, I'd better be going in the middle of the lane at car speeds to prevent anybody from trying to pass me on a curving descent. That actually happened once - I had decided to take it easy on that descent, stayed on the shoulder, and a coach bus passed me with a considerable lean (luckily, leaning away from me). One of the scariest traffic-related moments I've had on a bike.

79kph, since i started strava. On a downhill segment last fall. GPS says that speed was just a bit before a blind left bend followed by a stop sign, and was preceded by a sketchy blind right that had to be taken without touching the brakes. Stupid, stupid, stupid.
That's behavior of a guy who's going to break his neck. Which i did, about a month later on a different descent.
So yeah, not ever topping that PR.

I said sped up, not spliced.

You can easily fool the speedometer into doubling the listed speed by adding a second screw-on magnet to the wheel. That's why I trust accelerometers.

A couple summers ago I was vacationing in Park City UT, staying at a resort on top of a mountain that was primarily used for winter skiers. Each day to ride across the city towards any of the favorite routes of the local roadies I would have to descend that mountain, which included a ~2 mile section of 10% grade. Two days in a row I hit 58mph first thing in the morning.

Of course, you tend to forget about those milestones when the last thing in the day is having to climb back up that 2 mile 10% hill to get home!

Jazzguitar

I've topped out at a little over 50mph which was fast enough for me. 40+ isn't rare depending on the terrain and familiarity with the descent.

rousseau

I got up to 65 km/h once. That was a once-in-a-lifetime ride, but I'll never do that again.

gofastdontcrash

I've topped out at 53 mph, but I'm regularly hitting between 47mph and 50mph on my steeper descents.

I too enjoy speed. Probably an artifact of ski racing. Enjoy watching the speedo climb, but anything above 45 mph makes nervous about deer running out of the woods and doing a major impact. Wished there were some descents without trees so They could relax at your speeds. Great interweb name!

jim_pridx

My wife and I have been riding a tandem for over 35 years now, and we hit the mid 50s while going down one of our local hills about 25 years ago. Since the tandem remained very stable, the speed really didn't bother me, but I'll have to admit that I've been a little nervous about venturing into that territory again. Perhaps age has something to do with that......

Carbonfiberboy 

I used to do a double metric with my droogs. There was a long straight, steep hill with a visible straight runout. I'd tuck and let her run, topping out at 55. I called it "Cheecegrater Hill" because of the rather rough chipseal on it. Never had a problem on it, though. My road bike is very stable at speed.

gofastdontcrash

Thanks rsbob! I haven't had any close calls with any deer yet (even though they are in the area where I ride) but I did lock up the brakes and fishtail few weeks ago when I came flying around a bend to find a flock of wild turkeys in the road. The pucker factor was high!
