The problem is ambiguity. Sometimes you'll be unfairly judged by cyclists you're trying to pass. It will happen. Sometimes it helps to reduce the sting of the judgement with some perspective on what's going on. When you’re on a bicycle, cars are death monsters. You spend your time trying to keep distance from them. You wish they would all just disappear. ...

As long as you give a cyclist plenty of space, and obey traffic laws and drive safely in general you are OK. 1 meter or 3 feet is generally considered enough space when passing, but I know I prefer more. If you can move into another travel lane to overtake please do that. Don't follow a cyclist too closely before overtaking, it's really scary for the ...

Determining an acceptable risk level is really a subjective personal assessment, no one can tell you whether or not something is of an acceptable level of risk. As such I will give you my judgement criteria for riding on roads shared with automobiles. I avoid roads without a large shoulder or bike lane. While many still advocate for taking a lane, the ...

@Rider_X has already given a good answer. I would add an important consideration: local driver and cyclist cultures. As you and the map you cite indicate, there is little pro-cycling culture in this area. If you don't see other cyclists riding there, then don't do it yourself. The road you picture is quite poorly designed, even for motor traffic. That ...

My personal list in order of importance: Overtake when it’s safe to do so. This means no oncoming traffic (unless the lanes are wide enough to overtake even despite traffic) and that you can see far enough ahead. Don’t overtake on crossroads or crosswalks. Don’t drive too close behind. Bicycles usually don’t have braking lights, so you’ll need some time/...

Your rims can almost certainly take the extra width. The real question is can your frame, forks, and brakes? Only you can measure that. Based on nominal dimensions (and some approximations) you would need an extra: 2.5mm either side to the chainstays/seatstays and forks/brake arches. 5mm above (to clear the brakes) and in front of the back tyre. A few ...

You handled the situation perfectly. Congrats, you belong to the good, vanishingly small minority who does. You see, from my experience I would estimate the fraction of car drivers who obey the rules when overtaking bikes at about a single percent. At most. The vast majority of motorists seem to think that they have the right to overtake a bike even when ...

If you're going to change anything before the big event, change it now and allow time for any problems to arise, then be sorted out before the event. Generally, a 28mm tyre is said to give lower rolling resistance over a 25mm and has been tested, though using a 28mm at the same pressure as the 25mm could spoil some of the comfort advantages. The numbers ...

You basically get what you pay for, so there isn't any secret formula. Trek is one of the largest manufacturers on the planet, and is probably as good as any other on the market. But have a look at, and test if possible, other bikes as well as Trek, because different models have different geometries, and another geometry might feel better to you. Size also ...

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,...

This is not a proper answer. Its more a collection of notes gleaned from different sources. Feel free to add more if you find other things. 1989 The first Tour de Trump, a 10-day, 837-mile bicycle race through five Eastern states http://www.nytimes.com/1989/05/15/sports/dispute-mars-end-of-the-tour-de-trump.html Other site says 825 miles total, or 782 ...

Its to control the size of the field. The number of categories grows as the number of riders increases. This is so that you split people by ability more (for better consistency) and keep the fields sufficiently small. There just happen to be more men than women. If the number of women increase to be unwieldly with 4 categories, they'll presumably add a cat ...

What metrics can I use to make a judgement call about whether a vehicle's actions are actually making me unsafe The UK Highway code says they should give you as much space as they give a car, illustrations in the code suggest they should move completely into the next lane. At least one UK police force uses 1.5 metres as the minimum separation. My old copy ...

If you want to improve balance and control out of the saddle at any speed, even freewheeling, you just have to practice doing it. Note that balance while pedaling out of the saddle on a trainer vs. on the road will be very different as the bike is held firmly upright in the trainer With respect to power output: pedaling out of the saddle is usually done ...

An RD-5701 rear derailleur should work just fine as a replacement for an RD-6600. I've used an RD-5701 with an 11/28 cassette for the last 6-7 months with no issues, including swapping my crankset from a 50/34 compact to a 53/39 a few weeks ago.

Shimano 10 speed mountain rear derailleurs or 11 speed road derailleurs work with Shimano 11 speed road shifters. Shimano 7,8,9,10 speed road and 7,8,9 speed mountain derailleurs work with Shimano 7,8,9,10 speed road shifters in terms of cable pull.

For efficiency I would put the road tire on the back, as the rear carries more weight. However, front would be best if cornering traction was important. If the MTB tires have an aggressive MTB tread pattern the mismatch would be best addressed by matching tires and getting another road tire.

Well, 26 will feel a whole lot better than your current 23. You can get away with lower air pressure because of the larger volume supporting your weight. Lower pressure means smoother ride. Of course two tires of the same size can feel very different because of the quality of the casing and rubber. For commuting, I would say get as big as you can fit, which ...

From my experience, the single most important point is properly choosing your route. Google maps and the satellite view are your friends. For example, there is a 2x2 lanes road nearby. I see cyclists there quite often when I drive. It is an extremely dangerous road, 90 km/h, big lorries, no shoulder. There is a smaller, parallel road though. It is very nice ...

Fact: True pro-level road racing bikes from all eras, including but not limited to the current iteratons, prioritize being light as possible while durable enough, and the right kind of durable, for a pro racer. Fact: A heavy non-racer riding for fitness and pleasure doesn't really get any utilitarian benefit from the extra bit of weight reduction that ...

TR160-35 is the model number. They are 160mm Centerlock rotors. If your new wheels have Centerlock hubs, then you need either centerlock rotors or adaptors. If the wheels are 6-bolt, then you need 6-bolt rotors. Either way you'll want 160mm rotors and to keep it easy, I'd stick with Tektro rotors for this system.

Your technology is up to date. 53x12 is basically still the standard for road bikes today. If you want to increase the gearing, your best bet would be to install an 11x cassette, if not a Sram 10x. That said... If you are regularly finding your 53x12 too low it means one of three things: You are mashing (standing up in a heavy gear) instead of spinning (...

One of the considerations (assuming you are able to get a good seal) is that air loss under a tire burping may be worse than a tubeless specific rim. In CX this is definitely a consideration, especially if you are pushing the lower limits of tire pressure (e.g., < 30 psi on 700x33c is amazing on slick off camber turns, but it is easy to fold the tire in ...

There is significant debate over the statistical benefit of wearing a helmet or not. My guess is most of use wear a helmet just in case the "Helmets are safer' camp is right but wonder if they really are. I cannot imagine the difference between helmets from a safety perspective being statistically significant. "Road. XC etc are just marketing terms - the ...

Dangerous driving, in UK law, happens when "the way he/she drives falls far below what would be expected of a competent and careful driver, and it would be obvious to a competent and careful driver that driving in that way would be dangerous". Just putting you in an unsafe situation isn't (in itself) enough to constitute dangerous driving. You may be ...

It turns out there's actually some rather interesting science behind friction in the presence of water and salt. Various model systems demonstrate that salt solutions really are better lubricants than plain (distilled) water between rubber and other materials, and by enough to matter. Unfortunately little if any work has been done on the friction between ...

It is very much like with shoes: very personal. You look for one until you find it and then you use the same model for as long as possible. Or, one can use service of a tailor, or in this case, bike fit expert, for a price. Sit bones measurement is one of the most affordable things, as a simple cardboard can be used for that. For complex cases, a custom ...

I know this thread is super old but the 1990 version ran through my home town of Saugerties NY, ran through West Saugerties and up Devils Kitchen into Cairo. Platte Clove/ Devils Kitchen is a very steep incline and my dad was telling me that many of the bicyclist had to get off their bikes cause they couldnt make it up it (this road is closed during the ...

With a decent bike such as the one you linked to, it's not so much a question whether the bike can handle it, but it depends on how much you can handle. How fast you can go over a bump depends a lot on your riding technique: if you are able to shift your weight in the right way you can significantly increase the speed to go over the bump. If you are able to ...

Power output by itself is not a good measurement of performance. Performance of 300W for a 130Kg rider compared to a 80Kg rider is completely different. You should be looking at a combination of Power to weight ratio Time to complete a regular route/segment on garmin connect/strava. Heart rate How you actually feel during your cycle How well your bike ...
