Mmm my favorite subject speed. I have a hill behind my house that I have on nearly every decent attained above 90kph. The highest been 97kph. Problem is that there is a traffic light at the bottom and you have to break. It is about 600m in length and I have done a TT from bottom to top in 3:05. The other way round takes less than half a minute.
Just outside town I followed a cattle truck down a hill and got 101kph, as well as a lot of brown stuff from the cattle on the truck, yuck. Normally this hill will only allow tops of around 70kph.
On a local race I managed to get a speed of 93kph and broke away from my fellow riders down a pass. They later caught up and the one guy still said I was mad and he never saw anyone ride like I did. He said he backed off at 74kph.
Highest speed though was while I was racing in Holland. I had dropped off the main bunch to help a team mate get back to the group but he was nowhere in sight and I was told to get back in the group. Myself and another rider got together and chased the bunch. We were closing in quick and we were gaining some good time. There was a small climb and a very steep pass on the other side. I went down this pass at 110kph, may have been faster but I crashed and my computer zeroed after that. Last reading I saw was when the figures hit 110. A motorbike marshal said he was doing 107kph and we were dropping him. He pulled away and tried to warn us about a hairpin bend ahead but by the time he warned us it was too late. My fellow rider and I drifted into the side railing and came down at probably round 50 - 60 kph. Injuries were very little considering the speed but my wheels were totaled and my team car went past with my wheels on. The race doctor pulled me out of the race cause I had a head injury that was bleeding quite a lot. Otherwise I was fine.
Lived to speed another day. Hope to reach them speeds again, maybe even get faster. It is fun. :
Ooops these were done on a Colnago Master. The bike was probably between 10 to 12 years old at the time (1994).
My current bike a Colnago Carbitubo has been around 120 kph behind a bakkie but that was the previous owner that did that, also his computer didnt register anything over 105kph and he took the bakkies reading so it was probably only 105-110kph. I have taken it up to 96kph on the hill behind my house. As an Idea of my trust in Colnago I have gone down hills with no hands at over 70 kph.... It was as stable as can be. Wonderful bikes and I will not ride any other.
