Max speed
For anyone wondering, the max speed you can reach down a hill is
unrelated to what cassette you have on. I inadvertantly replaced a 12-26 with a 13-26 (I could have sworn the original had 13T written on it, but it's not like I had a choice given I was mail ordering and the supplier didn't do anything else, 8-speed wise). But it turns out you can do 87.45km/h on an Giant '05 OCR3 (2km/h faster than previously on that hill, and 5km/h faster than any time I have actually bothered to record it in my logfile). I refuse to confirm or deny whether I had a slightly hairy moment at the bottom, wondering whether I could completely negotiate the slight curve with the added nervousness of a truck coming up the other way. No speed wobbles though -- for a cheap aluminium frame, I guess that's something. Considering I only ever got to 86km/h once, drafting Gags down the warrandyte descent, I guess I can look favourably upon today's slight wind. Still missed my PB average by about 20 seconds. And today was with the bus on my tail for a km or so through some twisty passages -- added some incentive to crack an average of 60km/h through that section. I also refuse to confirm nor deny whether I got to my front lawn, struggled off the bike, poured the tap over me, and sat down on the gutter for 5 minutes. Seems kinda pointless to save a few minutes on the commute, then blow it all away by sitting on the gutter, but it was fun -- TimC I am very new to programming drivers so if I sound un-knowledgeable then it's because I am. -- first4internet's Ceri Coburn on writing Sony's DRM rootkit |

Perhaps a few other things as well. Assuming my computers were correct, I've reached 85 k/mh on three separate occasions, once on a single bike, west coast Tassie, and twice on a tandem, different locations Vic. I found all three downright scary. Almost blind from wind tears, one rock, pothole or twitch at that speed and you're dead. It's definitely a hoot, but not one I seek out. Cheers, Ray |

Also depends on the hill. If you really want to go fast, accidentally leave the brakes in the "remove wheel" position, which on a roadie still kind of works when you test squeeze and you're used to the feel of a disconnected MTB brake. That was a brown trousers moment at 60+... I also refuse to confirm nor deny whether I got to my front lawn, struggled off the bike, poured the tap over me, and sat down on the gutter for 5 minutes. Seems kinda pointless to save a few minutes on the commute, then blow it all away by sitting on the gutter, but it was fun So there was a point. I'm hoping for a Garmin 305 from Santa so I can do that kind of thing more often, though on my old commute I knew all the checkpoints. 30 minutes to the National Park was a good run... -- Dave Hughes - And you don't think the government lets you buy _real_ tinfoil do you? -- D.C.

Considering I only ever got to 86km/h once, drafting Gags down the warrandyte descent, I guess I can look favourably upon today's slight wind. Yesterday on my solo BR effort I decided to coast down the Warrandyte hill and see what speed I could hit. I put my hands in either side of the head stem, tucked my elbows in to either side of my knees (which I put in against the top tube), arched my back and basically went "head down, bum up". I was only doing about 30km/h or so as I rounded the bend at the top and I glud from there. Didn't look at the speedo until after I had slowed down to about 55km/h or so on the flat at the bottom and I discovered that I had hit 87km/h - not bad considering there was stuff all wind around. From memory, I think the fastest I ever hit down that hill was 94km/h and that was coming off of Blah's wheel when he was drafting Flying Dutch.........it's certainly pretty exciting to get within a foot or so of someone else's wheel at that speed!!!!

I found all three downright scary. Almost blind from wind tears, one rock, pothole or twitch at that speed and you're dead. It's definitely a hoot, but not one I seek out. Or 'roos in my case. I had sunnies on today, which saved the eyes. The top part of the descent is hideous with potholes, but I'm doing more like 60km/h through them. This is my commute home, so I'll probably come a cropper one day, just from the statistics (let alone my irresponsibility when on 2 wheels . But I'll enjoy it up til then. Mind you, I have only ridden 7 hours in the past almost 3 months according to my logs. That's the solution to not hitting a roo - ride less. Damn it. Rarrgh, it's a pain having cycling compete so much for limited time. At least I don't drive to work -- TimC Using top down development, you never have any working code.

Gags I remember that one - good times... I did 92.7 unassisted and 99 drafting a friendly tradie (they DO exist) down that hill. You know, there are no hills here in Qatar. I miss my bike... |

I am pretty sure that it is Harris Gully Rd - as you come down the hill from the Reynolds Rd end of it just after the fruit market and the left hand bend in the road. The hill is fairly long and it gets steeper about two thirds of the way down. |

I only rode down it once, and so I was pretty hard on the brakes.
