What's your top speed?

according to rollapaluza, 84.9kph (53mph). no resistance so that's prob about the same as descending down a hill

cant remember what GI those rigs are on

Thats completely different, there is loads of resistance descending a hill plus few people have the balls to go 'all out' like they would on a stationary rig.

i don't want to piss on le grys or john howard's chips but that's just wrong. Fuck off and pedal like the rest of us.

this is my top speed. dont pay attention to the john howard thing

I don't even understand what I just watched back there.. certainly wasn't someone going at terrifying legspeeds.

basically the gear was so high I had to be towed to 50 MPH to even turn it from my own leg power

I'm familiar with the concept Crane - in fact John Howard took a similar approach to yourself years ago - but I'm with Clintsmoker.. you might as well get launched off a giant catapult on 72/12 and see how you get on....

saying that - hold on, I'm going to dig up a clip if I can find it, bound to be a repost but there you go..

Who's that John Howard bloke? Is he anywhere near as fast as TheCrane?

I won't keep you hanging, I can't find it.

I think Hillbilly showed it me once. A Dutch dude going down hill roads on a road bike. He's a proper world class cyclist though. Car in front of him filming, he's hitting ouchtown kph. Ring any bells?

fair play to them but why not just get a motorbike? or a car? you are spot on about the catapult PJ , i mean it defys belief really. the sad thing is that unlike the dangerous sports club (who invented assing about down mountains on bikes and such like and might even have been the first real bunji jumpers) these guys don't seem to be doing it for a laugh or with any irony whatsoever

a much better use of ones time unless you are going to pedal under your own steam of course.

So I checked my speedo today, reset it, made sure it was calibrated correctly, pumped up my tyres and went out for a speed effort to see if my 45 mph or so on my computer was right. I could only get up to 36 along Queensbridge road. After going into London fields cycles I checked my computer again and my maximun speed was set to 65 mph! I'm guessing that the alarms must interfere with the settings, I'm dissapointed as I was sure the 44.9 mph was mine but on my efforts today I have to concede that it may be bogus. 45 mph is fucking fast. Maybe if I had a velodrome, clear track, a massive gear and the perfect bike I could get that speed, but it's not gonna happen on shitty london tarmac too easily!

Murtle broke the land speed record on the way home eg ved/ojhn.. he was worried about being mistaken for a midget and went BAM! track markskate moss

Hippy do you ever actually sleep or are there just 4 of you that work in shift rotation?

When you meet him he's agreat guy and it's a Jekyll and Hyde experience to think that the same person has nearly 20,000 posts!

Just to clarify in case anyone thinks that Le Grys & Howard/Crane were towed. They were towed from a standstill because of the big gear, but they did let go once they were moving, and then were moving under their own power, slipstreaming the car.

I don't think that's any less valid than downhill speeds. Plus Dave's effort had a classic Rover SD1 touring car, which is lovely.

Just tested yesterday doing 500m sprint intervals on my way home from work.. I'm able to hit 32mph, a bit of tailwind, and with 46/17, Marathon Plus 25's... about 150rpm says Rabbit's single-speed calculator.

But then, my shape is way off, that's why I'm starting doing interval training :) shit, I'm so not able to keep my speed up after about 400 meters of all out sprinting.

Measured with an Edge 705 GPS.

edit: oh, and the highest speed I have logged while biking is about 40, down hill on my touring-bike.

Fastest ever was 51.0mph on my Sirrus, downhill in top (50:11) last August at the Nurburgring in Germany.

Oh ok.....WAIT?!Did nobody else notice the location....?How did you get to cycle on a race track?!

IIRC the 'ring is technically a non-speed-limited toll road these days, so you can do round it on anything road-legal you like. Whether cycling on it is all that wise, I don't know. Given the numbers of wannabe Touring Car heroes thrashing ineptly round it I'm not sure I'd want to try, but I'd be interested to hear from anyone who's tried it.

Not a top speed post but I spent this morning doing a lap of Inner London, Battersea, to City, Islington, Kings Cross, Paddington, Kensington, Chelsea and home again.

Lovely morning for it!

With the traffic as shit as it was in most places, I'd love to know how much faster I was than the steering wheel hugging, cursing fucknuts in their 4x4s (esp, Kensington/Chelsea). I wasn't caning it too hard most of the time, but keeping with traffic and sometimes overtaking at decent pace was quite a nice feeling

Sleeping is for plankton and Tasmanians.

We shouldn't forget speed records set by riders of faired recumbents.

Depends, off camber bends really shit me up, straight descents and on-camber bends I am fine with.

Absolute nutters!

Can't find the vid on youtube, but I remember seeing a previous record attempt, on the first run the suspension wasn't correctly setup and the backend was jumping all over the place. The bloke still managed to stay on for the whole run.

After that I think he managed 128mph on the way down and broke the record.

Right then. I bought a new speedo yesterday from Lidl's for the princely sum of £3.90 just so I could join in on this thread. Took me 5 minutes to fit but 5 hours to set up and I'm still not sure it's correct. Anyways, went for a quick (or possibly slow) spin round the block and got a maximum speed reading of warp factor 1.819221216032059e-8
What cadence is that on 48:18 and do I need to try harder?
