They don't start slow because they are on a fixed gear (track) bike. They start slow because they are trying to coax the other rider into starting the sprint for the finish line before they do. The advantage is typically given to the rider behind the other because you have not only the element of surprise, but you also get a draft off the person in front. ...

You seem like you want three different bikes all smashed up into one, and the result is not going to be good. First, the time trial frame is not intended to be a track frame. If you're going to race at the track, use a frame and components that are designed for the track. For starters, the time trial frame will have a lower bottom bracket, dramatically ...

The rules for Track Races are here. In the Team Sprint: The leading rider shall lead the first lap and move towards the outside of the track and then drop back to leave the track without hindering the other team. In Great Britain's semi-final this is what happened at the end of the first lap: Jess Varnish (nearest to us in the picture) was the ...

Velodromes are not a suitable cycling venue for members of the general public. They require specialized equipment (e.g., higher bottom brackets to avoid pedal strikes), training (e.g., no moving up/down track without ensuring you have room, maintaining enough speed in corners), and discipline. Expecting untrained riders and/or unsupervised novices to ride ...

Some tips: Look at where you want to go (the exit of the turn) and not ahead or at your front wheel. Slightly turn your hips and waist to point to where you want to go (the exit of the turn). Also, thinking that you want to point your belly button there helps achieve this movement. Outside foot down (pressing the bike down), inside foot up. Outside hand ...

Two very different animals. The TT frame is built up with road components, the brake handles and shifters are a bit different but the front/rear derailleurs, crank, etc are all regular road components. The track frame is a single speed frame and many do not have holes to mount brakes...for Planet X you'll have to ask if the fork does or does not have ...

The guy using it apparently is Hans-Henrik Oersted who was sponsered by chinelli. The company recently did a rerun of two jerseys to honor him. The picture can also be found on cinellis website about the jerseys so i wrote a request for information to their customer service. They answered it is a handmade trainer build especially for Hans-Henrik Oersted in ...

Honestly, I don't think that a velodrome would accomplish what you are intending, taking the public from the streets to the track. Riding on the banks of a velodrome (Unless it's wide/long such as the 'drome at the end of Paris-Roubaix) is an accomplished skill, so what I'm afraid you'd have is a bunch of riders doing laps at the bottom of the track. Also, ...

The equation for total aerodynamic drag force on a bicycle is well-understood and, you're right, air density has a role in it: the higher the density, the greater the drag. As you guessed, density decreases with increasing temperature so warm air is less dense than cold air. It's also probably no surprise that density decreases with pressure. However, ...

It's as you suggest, a combination of a standard road cleat and straps as a 'belt and braces' approach. A quick google showed some packages of both sold together

I wouldn't. Track frames are purpose-built for racing at a velodrome. Your tri frame will have a much lower bottom bracket. This can easily result in a pedal strike on the banked corners of the velodrome. Pedal strikes on corners with a fixed gear are bad; since the drivetrain is always turning, it will cause your rear wheel to jump perpendicular to the ...

Any bike can be riden on the track but the question would be, does your tri frame have suitable drop outs for your fixed gear? Yes folks have rigged vert drop outs for fixed gear before but they usually are allot of hassle to keep setup just right. As far as angles for the frame go, a track bike is going to be really close to a tri bike for geometry but you ...

Hope this helps. The part of the international cycling union regulations about women's team sprint states that it is a race of 2 laps with 2 riders. Each rider must complete one lap each. The leading rider shall lead the first lap and move towards the outside of the track and the second rider shall complete the second lap on their own. A team ...

For your purposes, the biggest difference is the rear dropout (where the rear axle connects). The track bike will be much easier to set up as a fixie. I suspect the pricing difference has to do with features like bottle bosses, attachment point for derailer, cable routing stuff, etc, not from the TT frame being "better" in any other way. The TT frame has a ...

They're heavier, hotter (vents would do the opposite of what you're trying to do with an aero helmet, which is to route air up and over the helmet), and it's more difficult to turn your head (it doesn't completely prohibit turning your head but you lose the benefit of the shape as you turn it off-axis) so you have to depend on peripheral vision more. Plus, ...

Air density alone has a fairly substantial impact on speed, if all else is equal (and if my calculations are correct!) Based on the equation and from this page on cycling aerodynamics, and the air-density values from Wolfram Alpha, I came up with: At 300 watts, at 0*C, will travel at 39.34 km/h At 300 watts, at 10*C, will travel at 40.06 km/h At 300 ...

Also a very good pro tip is to do a little flick to in the "wrong" direction right before you turn in. say, you are approching a right turn, you've placed yourself on the left side of the road. Just before you start leaning to the right, yor make a small flick/turn to the left without leaning your body that way. This will tilt the bike to the right, making ...

From experience, (being an amateur seeing pros at events) a lot of people use Speedplays for better pedal clearance. You can also do something slick like this to create a clip/cleat combination.
