In road racing there are lots of way to try and gain an advantage (or not to give others an advantage). Because this is a friendly race, I will break it down into friendly, indifferent and hostile tactics. Update 1: The OP updated their question to make it clear that they were a beginner and the other rider was a more experienced road rider. So I ...

To a racer, rolling resistance and handling top the list; durability is far down the list. The coefficient of rolling resistance (Crr) for a racing tire on typical French or Italian roads used during a Grand Tour is about .004, or even lower. The Crr of a puncture resistant tire can be > .01. Crr scales like gradient, so the difference between Crr's of .01 ...

Answer: reset your expectations and give it a go. The first race I entered, my only goal was to finish. Second time I did it, the goal was to pace better and finish with a better time than my first effort. After that, personal improvement is really the goal, developing racecraft and strategy. When riding in a group/bunch/peloton/paceline of cyclists, you ...

Unethical, because you're imposing costs on the organisers anyway. Apart from the obvious "if you get hurt they're going to help you", they almost always face costs per participant and often have a limit on numbers. Violate those limits and the organisers will have problems. You're also causing wear and tear on the track, equipment and marshals. You can't ...

Let the co-worker pass and then draft behind them. It becomes a game of chicken to see who goes first. This is partially why road racing at the professional level is usually done in teams. The team works together letting riders take a turn in the front so that the race moves at a reasonable pace. The other option is to just give a good effort on an uphill ...

Puncture resistant tires are heavier relative to non-puncture resistant tires. They also have sloppier handling/less control/higher rolling resistance, and are typically harder to change (though professional racers will usually wheel swap). And you have the question of rider preference -- you're going to set the type of tire + pressures and what not, the way ...

The 6.8 kg limit is due to UCI regulation 1.3.019, which you can find here, and thus applies to all races sanctioned by the UCI. It was originally instituted in 2000 in order to ensure that manufacturers didn't produce racing bikes that risked structural integrity, to promote rider safety. At the time, with the then-current technology, that was considered a ...

Treating "competitive cyclists" as this single unified group (with three subgrouping) belies some prejudices. Like all walks of life there are a diversity of people, all with different motivations, morals and life experiences. As such there is no single correct answer your various questions. For example: are people in pelotons generally friendly, ...

The only way to be sure is to measure. You can use an app such as Strava during the ride, then look at it's analysis later. It will show you how fast you were going at each point, and also gives an approximation of your power output. We don't know what algorithm or assumptions it uses to calculate the power, but since it uses just one algorithm you can ...

This is a special device that gathers the following data, according to this article: the stage winner’s top speed, average speed and time per kilometer the fastest riders up key climbs the speed of the winner at the finish line the top speed achieved by a rider on the day average speed across all riders

If you have set of identical riders, and one rider puts a slower tyre on, they will lose if no-one gets a puncture (let's simplify and assume a time trial so we can ignore effects of the peloton). Anti-puncture tyres are slower as seen in R. Chung's answer. Of course for a real race of merely very similar riders who may be having good or bad days, it's not ...

Each type of racing is able to take advantage of certain team dynamics, and a few things are common across all disciplines. Specifics: DH/Super D: Downhill "teams" are more associated by sponsors and bikes than by riding together during a race. Since each run is done one at a time there's no drafting or anything like that. However, during track walks and ...

As already said in the title of the Wikipedia page, these bikes are intended for motorpaced racing on track. The backwards fork allows the rider to stay closer to the derny motorcycle for more efficient drafting. Since the races take place on track, with single riders drafting motorcycles, the handling is not that much a problem, but people have indeed died ...

I saw this question a couple of weeks ago and was interested in it, I have just got back from spending 2 nights at the Tour de France where I happened to stay in the same hotel as one of the teams. So I asked one of them. I'm afraid it has absolutely nothing to do with protection, or with ventilation. In fact you hit upon the disadvantage of a skinsuit in ...

Wheels and tires are the interface between the bike and the road; and are the parts that take the most stress (wear and tear) along with the bottom bracket. (IMO) lighter wheels will reduce the rotating mass (rotational inertia); you will need less energy to make the wheels accelerate/decelerate. higher quality bearings in the hub will reduce friction. ...

They are very similar but have to follow different certification rules. For example, under UCI regulations the saddle of a TT bike must be at least 5 cm behind a vertical line drawn through the bottom bracket (cf. Rules 1.3.011 to 1.3.025), there are constraints on the size, shape, and orientation of frame members, and so on. Triathlon bikes are certified ...

GC leaders are generally not out in the wind by themselves or taking many pulls on the front. They often put time on the field on climbs and in individual events like TT (which use bikes focused on aerodynamics). As such, in pack riding GC leader will likely favour a bike that focuses on climbing (light and stiff) and handling (note, aero road bikes are ...

Are you still looking for stage maps? I have the Tour DuPont program books from 1993, 1995 & 1996. They include a map and a profile of each stage. Also have Lance Armstrong's signature in the 1995 book. edit - Here's a first snap of the overall maps for the three years. Apologies for the quality - I've just snapped them with a phone in the meantime,...

Yes it has in fact happened several times, the most recent ones being 2017 (Chris Froome), 2006 (Óscar Pereiro after Floyd Landis was disqualified) and 1990 (Greg LeMond). Before that, the TdF was also won without a stage victory in 1922, 1956, 1960 and 1966. (see here). For your second question, Wikipedia has a list for the Giro (1913, 1946, 1951, 1961-...

I doubt it - at the moment - but we don't know how trained you are, and proper training will work wonders. This is likely to mean finding either a club or a coach. If your goal is to race, you really do need to find a racing club to train with. Round here there are several; all have mixed or women's fast group training rides, some also have junior sections....

Disc wheels have lower drag than spoke wheels. See Wheelbuilder aerodynamic data and Aerodynamics of High Performance Race Bicycle Wheels. (One link shows simulated data, the other measured). Most of these tests run up to yaw angles of 30 degrees. The argument is typically that at higher yaw angles (closer to side-winds) the rider would choose a spoked ...

Much of this is due to UCI regulations. They specify what shape and size of frame can be used. It is not allowed to add extra parts just for improving aerodynamics. See the UCI document Technical Regulations For Bicycles - A Practical Guide To Implementation (PDF) which covers most of this. As it says for Article 1.3.020, the frame elements must be tubular,...

I now realise "gran fondo" is American terminology for "cyclosportive". That sort of event falls loosely between audax and racing. The randonneuring community prize responsible riding, and tend to frown upon behaviour or equipment that could be deemed "antisocial". For example, most audax events require riders to fit mudguards, for the benefit of others. In ...

They are GPS trackers with a wireless data connection, GSM or EDGE would be enough for the data rate, but it might be something faster. The company supplying them is Dimension Data you can sign up for a free data report at the end of each stage here.

Not a complete answer really, but I've had a scan through this TdF data Twitter account and Greipel's winning speeds from his two wins this year are an average of 59.58 km/h over the last km and a peak speed of 67.03 km/h. Pretty quick. Edit: more stats for nerds here.

I’d say it’s totally okay if the road is not closed for the event and still open for cars and other vehicles.

The main reason is the 2020 Specialized Shiv provided by their sponsor is only produced in a disc version. You can see an article about the bike here: https://www.bikeradar.com/news/specialized-sworks-shiv-tt-disc/

The rear wheel is normal size (700), the front wheel is smaller (650). It was for aerodynamic reasons. By lowering the torso of the rider, the frontal surface of the rider became smaller. The configuration appeared first in triathlon and was later banned by the UCI in road and track events. Both wheels must now be of identical size i.e. 700.

To an extent, yes it does have negative connotations. The word was first used in cycling as an insult for Maurice Brocco, known as Coco,[4] in 1911. Brocco started six Tours de France between 1908 and 1914, finished none of them, although a stage he won in 1911 caused the coining of domestique. -- http://en.wikipedia.org/wiki/Domestique In road racing,...

Some people never do. In races, people push to the limit, and sometimes past it. And people make mistakes. So there will always be crashes. It's part of race craft to learn to read the corners and your competitors, to know when to make sure you are ahead or inside the risky riders. At this early stage of your career many of the riders you are riding ...
