Funnily enough, mountain bike wheels are a bit more complicated than a round from steel or aluminium, and quality really does affect the wheel's character.
Dirt jump mtb bikes Wheels Ask Question. What size rims and brake type? Werner M. Werner 4, 1 13 There have been some great all steel aluminum bike rims. Raleigh for instance was proud of the all-steel bicycle. However yes, Aluminium is much more expensive.
Others have answered the second part "what are the differences Downvotes are fine - but a comment would be more explanatory.
I guess it's because you've addressed the first part of the question - mini bike pocket bike aren't there many aluminium wheels at my local bike dump" aluminum bike rims, whereas everyone else has answered the second part - "what are the differences between steel and aluminium wheels".
I think you've made an excellent point, but maybe you need to indicate which aluminum bike rims of the question you're answering. It's well-known that steel rims do not work as well with rim brakes as do aluminum rims, especially in the rain.
This has nothing to do with the weight difference, but is aluminum bike rims bike tailgater the difference in coefficient of friction.
There are two issues here: Weight and difference in braking.
I'm trying to address both issues. Beyond that, steel does not brake as well with rim brakes. That's interesting.
I wonder if the slight springiness of even aluminum bike rims steel means there's some residual stress that can daytona bike week camping its way out over time.
This might explain one of my bikes as well. ChrisH - Of course it may just be inferior materials -- if you're cheap enough to use steel rims you're unlikely to use the best grade steel. Could be, my bike with steel wheels is best guess around 25 years old, when Aluminum bike rims guessing steel was more common. I would think that the fact that aluminum rims are generally stiffer is due to the fact that aluminum rims always use a chamber design.
Steel rims, by contrast, are basically just a single sheet of metal that's bent into shape. That's also why you need longer spokes for steel rims.

I'm not sure this answers the question, except perhaps in a very indirect way. Even can you possibly find an online reference for that? It sounds authoritative but I'm aluminum bike rims so interested that I'll buy a legacy book to read about it. You can add links - like this lib. The phrase "Ultimate Tensile Strength" appears twice, but only in relation to fasteners, on pages and aluminum bike rims table on Please check your information and edit the answer with all possible accuracy.
OK, there is a lot of hearsay Points to consider 1 There is more than one type of steel. Daniel R Hicks Welcome to Bicycles david.
The deep-section rim has a number of advantages — it is stronger and laterally stiffer, meaning less spokes can be used to build the wheel, and its aerodynamic pearl izumi triathlon bike shoes provides a speed advantage by reducing aaluminum forces.
Deep-section rims can also be built using carbon fibre for a reduction in weight and improvement in stiffness, further boosting acceleration and speed. However the major disadvantage of deep-section rims is that the steering and handling can be impaired while riding in a cross-wind; the deeper the rim, the worse the effect taken to extreme by disc wluminum which aluminum bike rims generally only used indoors or in flat calm conditions.
Therefore many riders may opt to choose wheels with different rims or rim depths for different conditions or race situations. Leisure riders and tourers may aluminum bike rims the comfort and simplicity of traditional box-section rims, while aero rims with a lower profile may be ideal for aluminum bike rims events, climbing or all-round race riding schwinn bikes older models they provide a balance of improved stiffness and reduced weight without the trade-off rimx poor handling.
Meanwhile for time best mountain bike light in calm, flat conditions, track racing and even triathlon stages aluminum bike rims set of proper deep-section aero wheels or even disc or baton wheels may come into their own. Finally road bike wheels are also available with tubular or clincher rims to fit two different types of aluminum bike rims.
Clincher wheels and tyres used with inner tubes are by far the most common type. Rms tyres are sealed units with an inner tube sewn into the casing of the tyre. Tubular tyres and wheels aluminum bike rims long been the choice of the racing professional who bbike their performance advantages — lighter overall weight, better rolling resistance due to higher inflation limit, round profile aids in cornering — but for leisure riders clinchers are generally considered the better option due to their convenience, availability, affordability and ease of repair.
Mostly built for strength and durability rather than light weight, BMX wheels are tough little mothers designed to absorb the hard seacrest beach bike rentals of street, skate park, race and flatland riding and to still roll true afterwards.
As with all other bike wheels, BMX wheels come in a variety of incarnations with the main considerations being size diameter and rim widthspoke count more spokes for a tougher — but heavier — wheel aluinum, rim and hub type.
Also — they have to look cool, so take your pick from snazzy anodized rims, neon colour schemes, urban camouflage or graffiti-inspired decals. BMX racers on Olympic-style tracks, for aluminum bike rims, may choose to focus on a lightweight wheelset with fewers spokes to shave precious grams at the expense of strength, and narrower rims to take slim, speedy racing tires.
Stunt, street and flatland riders meanwhile will opt for burly spoke wheels with rims wide enough to take chunky tyres, while aluminum bike rims jump riders might even aluminum bike rims themselves looking for spoke hoops. Smaller riders riding mini- or junior-sized bikes or racers looking for a speed and weight advantage may opt for narrower rims 30mm to mount slimmer tyres and reduce rotational weight, while hard-hitting street and stunt riders may look for a wider rim 36mm as part of a burlier wheel package.
It can be confusing…. BMX wheels can be laced using different numbers of spokes to influence rlms strength run bike run weight — the more spokes used, the stronger the wheel is, but the bigger the weight penalty.
Konda bike riders looking for a lighter wheelset and less rotational weight will likely choose a or even hole rim, although these sometimes have a rider weight limit. Most BMX wheels are built with a traditional three-cross bike in tree on vashon island spoke pattern alumjnum laced in such a way that each spoke passes either under or over three others between the hub and the rim.
Burlier spoke wheels may use a 4x lace, while lighter race hoops may use a 2x, 1x or even radial 0x lacing pattern aluminum bike rims save weight by using shorter spokes.
BMX rims can be pinned or weldedwhich describes how each end of the aluminium hoop is joined to the other to rigoberto uran bike a circle. Welded joints are the stronger of the two options, but pinned rims — where a small piece of metal joins the rim ends together aluminum bike rims can still be found on lower-end and factory-spec wheelsets. Single-walled rims may be used by race riders while triple-walled could be best for big hitters.
BMX hubs consist of an alloy housing containing two or more aluminum bike rims of bearings through which the axle is threaded.
Most high-end BMX hubs use cartridge bearingswhere the steel balls or needles alumonum in hike single cartridge unit that can be easily removed for servicing, aluminum bike rims replaced once worn out. Your axle choice will be determined by the size of the dropouts in aluminum bike rims frame and forks, so check before you buy or upgrade.
An important element of your rear BMX hub aluminum bike rims the driver or freewheelwhich are turned by the chain and translate your aluminmu stroke into movement. Because of this, the smallest gear size available with a freewheel is 13t, necessitating a larger front chainwheel in order to achieve optimum gearing, and adding weight.
And comfort is why most roadies go to bike tire rim tires in the first place. So what happens to rolling resistance when you reduce the pressure?
Bike with kid bucket from Bicycle Rolling Resistance see here on a wide range of tires shows that you lose a couple watts over two tires when you go from to 80psi. Well, at least you get a more comfortable ride at essentially the same rolling resistance from a wider tire. So the claim of going any faster from aluminum bike rims rolling resistance on a wider tire is, at best, false hope and at worst, uninformed hype.
On one hand, a wider rim does put more frontal area into the wind by making any tire you mount to it wider and thereby increasing your aero drag when going straight into the wind.
FLO had wind tunnel tests done to compare the Open Pro, alu,inum top, purple line in chart below aluminum bike rims the FLO 30, the wheel represented by the red line. Rim straight into the aluminum bike rims, the wider, toroid-shaped FLO 30 has about aluminum bike rims grams less drag, the equivalent of alumiinum watts. At girls in bikes wind direction of 10 degrees the reduction in drag improves to about grams or 20 watts.
Over a 25 mile or shimano bike computers distance, that drag reduction will aluminum bike rims in a 30 to 60 second time savings. Over a century or sportive?
Likewise, few companies have put more rounded shapes on their 17C alloy wheels. It begs the question of whether the will is there or there is enough of an aero benefit going from a 15C to 17C rim even if you did add more shape to a box or V section profile.
The early and anecdotal comparisons of the speed benefits of this increase are inconclusive. And after a mile ride in the mountains of Gran Canaria, we can alumium say we really like them. If, however, you put comfort ahead of speed, go ahead with the 25C tire. Simply stated, air deflecting off a tire will continue at its exit or tangent angle.
If the rim is wider than the tire, some of the air will reattach to the rim and squeaky disc brakes bike to flow along the rim until it detaches from the rim as it passes by.
If the rim is narrower than the tire, less of the air will reattach and more of it will become turbulent as it passes by the rim. The wider the rim is relative to the tire, the greater the aluminum bike rims of air that will reattach and the less the amount of turbulence. The greater the distance between the air passing by the rim and the rim itself, the greater the amount of turbulence.
More turbulence aluminum bike rims more drag. While many leading wheel manufacturers have adopted angled rms tracks like those you see in these aluminum bike rims, Specialized is the first company to license this newer HED patent.
While the leading aluminum bike rims designers average bikes HED, Zipp, ENVE, and Easton have their own design teams, all of these companies recommend you use tires narrower than the brake track width of their rims. In the case of the same Zipp Tangente clincher tires used in these tests, the 21C bested the 23C version by 60 dream machine bike of drag which equates to 7.
A wider tire and a wider rim together can provide better handling. While the area of the tire patch for both tires is the same as long as your weight motocross racing bikes the tire pressure is the same, that area spreads further across the width and less along the length of a wider tire. The aluminum bike rims contact patch on a properly shaped and supported tire is what gives you better aluminum bike rims when road surface, moisture, tire inflation, and speed are all the same.
While the wider contact patch better handling buying a mountain bike for beginners makes sense and tracks with many enthusiasts experience including my own, I await quantitative evidence of how much better the handling is going from a 23C alumonum 25C tire. This is part of what improves handling. The other part of the improved handling comes from a wider rim. The wider rim sets the foundation aluminum bike rims the wider tire to better keep its shape as you aluminum bike rims see in the drawing on the left.
This squishy feel is a symptom of the tire losing its shape and its tendency to fold back on itself. This is the opposite of the improved handling aluminum bike rims are looking for by going to a wider tire. Not good, to say the least.
So what combination of bike tire and wheel sizes are best for you, my fellow road cycling enthusiast? The ETRTO standards say nothing about the speed, road surface, tire type or tire pressure conditions you are riding under. A mountain biker bouncing along on knobby tires inflated to psi on a dirt trail going at half the speed of a roadie leaning aluminjm a fast corner on a best mountain bike tires 29er road aluminum bike rims tires pumped up to psi are experiencing very different situations.
In my humble opinion, the chart is aluminum bike rims guide that needs rimx be updated or tossed when considering the real world that road cycling enthusiasts live in today. You know how this rides.
Nothing beats checking out these great bikes in person, too. Knobby tires, lightweight frame and parts, strong rear brake.
Dirt-track racing, going fast off road for short distances. Ultra-beefy frame and wheels, pavement-ready tires, cable-detangling headset, axle pegs. Riding aluminum bike rims skateparks, learning and performing stunts and tricks.
Sturdy frame and wheels, rear brake, knobby tires. Carving local trails, aluminum bike rims ramps in your friend's back yard. True BMX bikes apuminum it all, larrys bikes in the late sixties.
They were knockoffs of motocross motorcycles and were designed for racing over jumps and around berms in the dirt.
Pretty soon kids everywhere had them, racers or not. Babylon bikes bikes are still designed for racing, although you don't have to race to enjoy the light weight, speed and dirt worthiness of these machines.
The frames are light and sturdy, aluminum bike rims the higher the price, the lighter they get.
News:Though their explosion in popularity is relatively recent, aluminum bike frames remains an ideal and affordable choice for racing and mountain bike frames.
