What makes road bikes fast




















For example: if you reach an incline, you should shift right before you begin climbing. If you do it once you are already halfway up, it will make for a slower shift and you may even hear some grinding. This is because you are shifting as you apply the maximum amount of pressure to your pedals because you are in the middle of going uphill.

The higher gear may seem faster to you because it thrusts you forward at a more powerful rate than a lower one, but it can also exert your energy too quickly. While we talked a little about the type of tire and things you can do to limit the weight the tire adds to your bike, there are still facets of your tires that can contribute to overall speed that are isolated from the weight.

You can look at your tires a few different ways. You obviously need them to be durable and agreeable to the terrain you plan to use them on, but you also want them to be the proper type and size for your bike. Within these parameters, there are ways to increase speed while checking all of those other items off the list as well. The tire pressure can really be an important factor. It just means you have to be diligent in checking your tire pressure and understanding how it can affect your ride.

If the tires are too soft, it will mean the rolling resistance will become greater, meaning you will need to exert more energy to go the same speed as if your tires were properly filled.

If they are really far under what they should be, then it also exposes you to a higher risk for pinch flats. While a firm tire will mean you can access your average speeds and excel easier, there are still benefits to a slightly less firm tire.

If you fill it to around 90psi, it may not be as fast on a flat, smooth straightaway, but it will result in increased grip if you are taking hard turns. So if you are looking for speed on a windy road, the slightly decreased tire pressure may work to your advantage. But if you are more concerned about straightaway speed, keep it right around the full psi so it is nice and firm and will not require additional effort to go the same speeds you are used to.

Cycling Weekly has a great guide on selecting the best road bike tires for if you need some help in your purchase process. When you wash your bike regularly and wipe away grime, mud, dirt, sand, or any greases that build up; you are ensuring it will work at its fullest capacity. Maintaining the cleanliness will also help the longevity of your bike and make for less trips to the part store for you over the life of your bike. Be especially careful during winter months if you are still out on the roads when the weather provides an opening.

Salt and sand from the road can easily get caught in your drivetrain and cause issues that will slow you down and could even be detrimental to the bike. If you make this into a routine, it will be easier on you as well. Just give yourself a couple minutes at the end of each ride to wipe everything down. This will save you time if there is a lot of build-up and you end up needing to disassemble certain pieces in order to clear anything up. Not only is cleanliness crucial to upkeep, but making sure you are properly lubing the chain is also a key maintenance concern.

Being certain that your chains are properly lubed will make for a more efficient drivetrain, a smoother ride, and ultimately—a faster ride. It all comes down to the aerodynamics of the bike and how you ride it. Forcing the front end of the bike slightly lower will be a big win for speed junkies out there. As long as you have spacers between the headset and stem, then this will be fairly simple. You will remove the fork, take out a spacer, and replace the stem. While the slight lean forward will help in the science of your aerodynamic ride, it may not feel right to you and your center of gravity.

Otherwise, you will actually end up going over the handlebars. This should also be heavily considered if you are going down a lot of hills. Any changes to the structure of the bike will result in a slight shift in the way you ride it. Your posture and body language on the bike will be important to be wary of if you make an adjustment such as this.

Making changes in increments will also help you adjust. Improving your speed on a road bike will include increasing your fitness level, interval training, and cycling cadence, which is the speed at which you pedal. I talk about cycling as it relates to exercise in this blog and you can read more about it, here. Being able to cycle faster will take having fast-twitch muscles to spin out the bike and move it forward faster.

But in order to build fast-twitch muscles, you will need to lift weights or do strength training exercises. Now pedaling cadence, which might be more important than a faster bike, will be how many revolutions you can spin in a minute riding. Most cyclists can spin at 90 RPMs and reach speeds that range between mph You must be able to keep a good cadence going over a long period of time in order to cycle fast. Cadence becomes even more crucial when cycling up hills fast as well.

Consider some additional free tips on becoming a faster rider:. When it comes to speed, are wider tires better than narrow ones? Most road bike tires are narrow for a reason and it has to do with rolling resistance. Narrow bike tires are smoother and more agile and allowing you to roll quickly since they are not as heavy. Can I make a bike faster with sprockets? On a geared road bike you have many options to change your gear ratio.

Some cyclists prefer gear ratios that are higher than what casual riders use. Importantly, this doesn't even account for suspension losses. With the thick frame, suspension in both fork and seatpost, and hub gears, I'd think 18 kg 40 lb is more likely.

Racks, fenders, kickstand. I really can't imagine this thing being under 40 lbs. This is sooo biased! Besides, weight doesn't affect speed all that much on level ground.

You could easily set up a road bike so you have a very upright posture and wind up with, IMO, a much better "upright" bike than any hybrid with its "one hand position, all of them uncomfortable" straight bar.

Add a comment. Your hub dynamo will also be adding some resistance. Argenti Apparatus Argenti Apparatus Thanks for the nice explanation, so actually all these nice gadgets make you slower in the end?

Test ride a few and find out. The hub dynamo has very small resistance. It provides 3 watts and resists at around 6 watts. Drag increases with the square of velocity.

Power increases with the cube. Show 4 more comments. Three reasons: Smaller air resistance due to primarily smaller frontal area and secondarily thinner tires. Smaller rolling resistance due to slick tread pattern, less puncture protection and smaller tread depth, narrow tires and higher tire pressures.

If going or accelerating very fast a riding position that's optimized for hard pedaling, so what might feel like same effort may actually be a higher effort on road bike! Two very small, almost insignificant reasons: Weight. It is a non-issue: main resistance is air resistance, weight plays no role in it. Light weight is nice when going up hills, but then high weight is nice when going down hills.

Hub dynamo. A non-reason: Positive attachment between pedal and shoe. The reason this is a non-reason is that you don't push up with the back pedal when not accelerating, you just support some but not all of the weight of your leg. However, 1. More mass can make for a smoother ride, but only with good full-sus on rough terrain. The upright position on city bikes really does make pedalling a lot less powerful, and I think this isn't just that you put in less effort but also that it's actually inefficient because body parts keep sloshing back and forth in useless, yet muscle-demanding ways.

Also on the weight issue. While it doesn't make much difference when at speed it IS a big issue when accelerating. In a city environment you are likely to spend a significant amount of time slowing down or stopping due to traffic and then accelerating again.

I use both a road bike and a hybrid and I get back up to my usual cruising speed far faster on the road bike. And the slight gain going down doesn't make up for the extra effort needed to go up. I know all about hills and weight Weight doesn't play a part on downhill speed. A 1kg hammer falls at the same speed as a 30kg anvil, remember physics? Show 3 more comments. Ross Millikan Ross Millikan 2, 11 11 silver badges 17 17 bronze badges. It's Faster With high confidence, I can say that virtually any road bike you test ride will feel like a sports car compared to the bike you have described.

The Differences I can attest that putting slicks on your mountain bike and making sure you have tubes that can go up to psi or so will also make a huge difference on your road performance. Conclusion Each of the differences above would be noticeable all by itself, if you just compared bikes that differed in a single feature. If you can afford it, you should definitely get a road bike! You will not be sorry. Lawnmower Man Lawnmower Man 2 2 bronze badges.

Toe cages are just fine on a road bike, especially one that's going to be used around town: needing special, awkward shoes for your bike makes shopping and errands much less convenient.

While, in principal, you can pull up on the pedals with clipless, most people don't and even pros don't do it much. You can certainly exert backward pressure with toe cages without needing to dip your toes very much. Fenders and a rack probably won't be transferrable from a mountain bike actually, I think the asker is describing a hybrid with front suspension and a suspension seat post, but that doesn't really make any difference.

Most road bikes don't have mounting points for racks, and the fenders on a hybrid or mountain bike will be designed for wider tyres and probably won't fit a road bike even if it does have mount points. The asker might want to consider a touring bike, which will have rack and fender mounts. No bicycle tube can hold psi on its own. Bicycle tubes are prevented from expanding and bursting by being held in place by the tire and rim.

Exceeding maximum pressure ratings on a large bicycle tire can be dangerous. If you pump a 2. There's a reason bike tires can be LOUD when they burst. You can effectively apply power without clipless pedals on the back stroke. It's done by supporting the weight of your rear leg. It's also worth checking the brake cable for stretch or signs of wear, although if you're keeping your bike clean then hopefully this shouldn't be too much of an issue. The Frenchman expressed doubts that not every team is sticking to the same rules.

The woman failed to stop at the scene of the incident, claiming she thought she had hit a fox. Cycling Weekly is part of Future plc, an international media group and leading digital publisher.
