The short answer is: not that difficult. The long answer requires some explanation. The equations of motion for a rider on a bicycle are well-understood if not always well-known. The power needed to propel a bicycle on firm flat ground (as on a velodrome) varies approximately with the cube of speed. Thus, to double your speed, you would need to increase ...

It can be considered "impolite" by roadies, but not because of the bike you were riding or the fact you didn't take a pull (although I am sure some will argue for this). The main reason random drop-in riders are generally frowned upon are because of: the dangers associated with unpredictability of a new rider lack of insurance coverage Potential ...

Since you say you're looking to become a triathlete soon it's far too early to be thinking of advanced training aids like power meters. The first few things to do (not necessarily in this order) are join a tri club enter a triathlon or two join a tri training squad observe your (comparative) strengths and weaknesses get a well recommended triathlon book. ...

It's doable although it doesn't make sense from a cost perspective. Only do it if you have an emotional investment in the bike or want a fun project that will teach you a lot about bike mechanics. To give you an idea, I bought a 1975 Peugeot UO18 Mixte (a woman's road bike, perhaps similar to your mom's) that had been stored in a barn and turned it into my ...

This is what I tell everyone to get first when they get a new bike: Seatbag, to hold the following: Spare tube (maybe two) Small multitool Mini-pump or CO2 inflator Tire patch kit 2x tire levers That assumes you have bidons and cages. Those six things should get you by for many miles and should get you out of any trailside emergencies. As with ...

In rapidly descending order of importance ... (see Why I chose these priorities below) Practice track stands. See How to do a track stand? This teaches balance and slow bike handling skills. Also practice riding in confined spaces (the last time I fell off was trying to do a U turn on a path that was 4 ft (1.2m) wide :-) Learn to jump both wheels off the ...

Most road bikes are the equivalent of an open-top racing car. You just don't ride them in the rain. And if you do, you are expected to be hard core enough that a little rain isn't worth the aerodynamic drag that the fenders would cause. And there's also a reason that hardcore racers wear sunglasses during the day or transparent glasses in the evening -- they ...

I think the terms used here are a bit confused. Rather than saying that a road bike has 22 "gears", you should be saying that it has 22 "speeds" (or more correctly, as pointed out in the comments, "gear ratios" is the technically correct most accurate term (when people say 'gear', they are using it as short for 'gear ratios')). Even that can be a bit ...

If you are riding near your aerobic limit you'll definitely discover that you've lost aerobic capacity during the next 12-24 hours. It can take that long to replace the red blood cells you've lost. Since a blood donation is about 10% of your blood capacity, your aerobic capacity will be down by 10% I wrote the rest of this before I saw your comment that ...

You have an older pre-cartridge bottom bracket. The bottom bracket is the axle and bearing assembly for the crankset. Rather than sealed bearings it has either loose ball or caged bearings. While the bottom bracket is assembled the cup is adjusted to the correct preload. Preload determines how much movement there is between the bearings and the axle. It ...

As already said, aerodynamics are less important to MTB's, but otherwise its largely convention and fashion that dictate what people wear. A vast majority of MTB'r are not wearing basic shorts - they are usually wearing shorts made for riding, including padding just like Lycra road shorts, flat seams and materials designed to withstand the rigour of riding. ...

You have a couple different options. I think the cheapest would be to switch to a compact crankset which would change the front chainrings from 52-39 to 50-34. I'm pretty sure you could do this while still using the same shifter. Changing the front shifter is required if you want to go from a double to a triple, as is changing the front derailleur. If you ...

Upgrading an older bike is typically not economical. Parts are typically not cheaper. Parts are not as available. That drivetrain is not compatible with a modern bike. Bikes have gotten better. Little faster, lighter, more comfortable, and easier to service. You can find decent to nice newer model used bikes for $400. Find someone that bought an $800 ...

It depends on how the fork is engineered for safety. While its plausible that the curved shape does add to some shock absorption, that is determined by the width and construction of the fork tubing. You could design a fork which was reliable and curved in aluminum or carbon or whatever, but the engineering wouldn't be the same as a steel fork. Whether the ...

Yes, absolutely. Clothing is mostly an issue of personal preference. Performance fabrics and things like spandex don't make that much difference for short stretches, and their advantages become more pronounced and valuable the longer you ride. 11 miles is somewhat of an intermediate distance; in regular clothes you'd be totally fine, assuming that the ...

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.

The question, mainly, would be, do you feel there is a definite peer pressure around this things? There is undoubtably fashion in a lot of cycling, but there there is in everything. Peer pressure would depend on the group. or a definite selling interest from shops? Yes, but then, that's why they're there. have you ridden with no uniform on ...

Riding at 30kph average for 3 hours, in a hilly area is a solid effort. Assuming your pack riding skills are sufficient, you will also likely do fine in in a club ride that averages 30-40kph (but see the pack riding primer below). Club rides will have a faster pace than what you are riding now, but you will also be working a lot less (about 30% less) at any ...

Cannondale with it's new Boost 148mm rear spacing standard could fit some more gears theoretically without making the chain thinner. But the real question is if more gears are actually needed. What really matters is the cassette range which is determined by the smallest and biggest cog wheels. Now we have the smallest cog with 10 teeth, and there was a ...

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

Road typically has a smaller range. A road bike will typically come with a short cage derailleur. Where a mountain will typically come with a medium or long cage derailleur. Yes the mount on the freehub is compatible. It is about the range capacity of the derailleur.

Other? I would not count protection as the first. The cage is a lever and some edges. A water bottle is not exactly an impact attenuator. And you have the chain ring to get past. You pretty much only see a third on touring bikes. It is the least convenient location but it is a third location. Three bottles or a frame bag and one bottle. Pretty much ...

Could be as simple as the wheel rubbing on the brakes - rotate the pedals and listen for a scraping noise as the wheel contacts the pads. If this is the case, check that the wheel is true by observing for any wobble side to side as the wheel rotates. If that looks ok your brakes probably need adjusted away from the rims. Start here for brake adjustment ...

It is not allowed by UCI rules, but comissars usually allow it if it is due to mechanical reasons and used to get back to the peloton, since they have discretional ability to decide. Time penalties or disqualification if used to gain advantage over the peloton. So, rule enforcement may vary depending on many circumstances, and I guess they don't want to lose ...

The key point in your question is I get on the bike and ride hard. There's nothing wrong with riding hard, but it sounds like you're riding too hard for your knees to be happy. Since you like doing weights, I suspect that you like to push the pedals hard, and this is causing the problem. Bike fit issues can cause knee soreness, but they also tend to have ...

As far as assisting at race pace - a cadence of 90 or 100 is not a limit for an electric motor designed for it. With the dollars involved in cycling generally, and at elite sports specifically, I do not see any barrier from an electromechanical perspective. Most importantly for an elite rider, the motor can be optimised for a cadence between 85-95 - a very ...

Off the bike many forms of exercise will help. Yoga and martial arts in particular will help with balance. On the bike consider mountain biking to help your road technique. A mountain bike with no shocks even better. Once you learn to negotiate rocks, roots, and drop offs then a lot of the low speed stuff that happens on the street seems easy. ...

Sometimes I carry a fuel bottle down there when touring. It is out of the way and if the bottle happens to leak it doesn't cause much trouble – certainly not like having a leaking bottle of white gas in a pannier…

These are referring to pad spacers. They essentially increase or decrease the amount of motion you have when moving the brake levers. See page 16 of the following PDF for a better diagram: Shimano Brake Levers User Guide

I currently ride on Rubino Pro Slick tires, and have used various Vittoria tires for decades. The Vittoria Rubino tires you are using have similar wet grip to what I use (dry grip will be the same). The pressures you quote are good. I get the impression that both incidents occurred in the same corner. If that is the case then I would strongly suspect oil ...
