downhill speed

[Grayskull]

 

NOS on a car is Nitrous Oxide - that into the fuel system giving and instant boost of power

 

 

 

"NOS" for the cyclist = methane gas - but lets not worry about that too much

 

 

 

 

stay low - its better for the aerodynamics

and like HR said - keep your arms loose

you can hold onto the lower part of your handlebars

and be careful of objects lying in the road

and wind - a gust of wind can quickly throw you off balance

Clocked 79.6km/ph on my MTB going down Irene in Somerset before and that was into a slight head wind.....going that fast on dirt is another story, only clocked 64km/ph

[L'Bie]

 

I clocked 80km going down sandton drive' date=' shot through the red robot (bad I know) and did not get a fine. Spoke to a cop and those ones activated by lines dont pick up bikes but the radars do - doubt you will get a fine though.

 

Its the most amazing feeling going fast!!

 

Still want to break the 90km zone or..... the 100km zone (although that seems scary!)

You don't have a numberplate. How are they going to send you a ticket?

BTW did 89.9Km/h down Vissershok with the South Easter pumping. Raise your arse out of the saddle and keep the elbows and knees flexible and enjoy BIGTIME!!

 

[downhilldemon]

did between 75 - 80km (difference in speedo's on 2 bikes) off road down a really steep hill on XC bikes. couldn't get the bikes to go faster. it gets a bit unstable but great feeling at the bottom of the hill. i'm not to sure that i'd want to live if i came off the bike at that speed just wearing normal licra. (spelling??)

[Capri Wheeler]

speed limits only apply to petrol-driven vehicles (diesel also obviously)

I made sure to consult a lawyer before trying stuff....

 

 

I've done 76 on a slight negative gradient but when I was in CT in the holidays this guy next to me did over 90km/h down suikerbossie

 

[Serendipity]

I got snapped going down Kaaimans Pass on the road bike near George by the permanent speeding camera they have got there. According to the GPS I was doing 72km/h at the time. They will have a tough time sending me the ticket though. If you do get trapped by the Camera with the Traffic Police operating it, technically you could get prosecuted.

between 8-10km/ph or i normally go up from spanish farm side (parelvalei)

[parabola]

Theres a mountain called Constantiaberg behind my house, and theres a tar road leading to the top up to the radio mast. Its about a 600m vertical descent with loads of corners coming down into Tokai arboretum. First time I rode down I thought to myself, hey this is pretty fast, only to see I was clocking 65km/h. Almost shat myself as I wasn't sure if my bike could even handle those speeds. More recently I went down there with another heavier rider who was hitting almost 80km/h. Its quite a thrill when you get to the corners and try to brake without skidding.

master216 tell me quickly: i start off uphill lord charles at about 13-14 km/h and further up i slow down to about 9...is that ok..im not a big girl, and on mountain bike. i measured from the robot to the bridge is about 1.1 km stretch...as you go round the bend the last little bit is the steepest. only been cycling 7 weeks and not by far strong enough...

 

thanks

if on mtb.. i prefer to stick to dirt roads.. Its way more fun flying through the air after a successful bunny hop!<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

Tar scar.. dirt only hurt..

 

Who needs speed.. if you can make that 90dgree turn after a drop off?

Wicked Cool!! I am so visiting George with my road bike!! Will put a plate with my postal addy on the bike and frame the fine!

[decibach db]

We go speeds regularly of 80-88km/h on the Tandem...

 

92km/h was the fastest I recall down butchers in the south of JHB, on a tandem.

 

Cant think of a faster way down  a hill other than a Tandem.

 

 

[stratus5]

86 km/h down Visserhok before I sat up to slow down a bit. Dont really feel in control any faster than that! 

 

Beware the higher speeds though, birds dont seem to be as aware of you as normal

 

I ride a motorbike and have had very few close shaves with birds over the years, but let me get over 80 km/h on a bicycle and its almost guaranteed some dumb pidgeon is going to try and fly into me

[droo]

93 km/h down Ou Kaaps in a south easter. Never had a bird problem, but a christmas beetle at 93 is pretty hard...
