Bike Wheels: Find out how to Select



After you’ve ridden your bike lengthy sufficient, your wheels attain some extent the place they have to be changed. Alternative mileage may range from a number of thousand miles to 20,000 miles or extra, relying in your street or path circumstances, your weight, how a lot general weight your bike is carrying, how aggressively you journey and, most significantly, how a lot braking you do.

When to interchange your wheels: Some rims have a substitute indicator, a gap or groove that slowly disappears because the rim wears down. In case your rim doesn’t have a put on indicator, you possibly can test the rim floor for a slight concave melancholy or different indicators of extreme put on.

Rims and spokes are additionally topic to metallic fatigue ultimately, so you must ask the bike store to evaluate your wheels’ well being when you’ve been driving on them for a number of years.

Contemplate upgrading your wheels to provide your self a efficiency increase. A wheel improve can assist you journey sooner, climb extra effectively or sort out downhill terrain extra aggressively.

You may even contemplate customized wheel constructing. Whereas this may be your most costly choice, it permits you to select every element of the wheel individually. It additionally enables you to exactly match your wheels to your driving wants.

Bike Wheel Compatibility

Whether or not you’re changing your present wheel due to rim put on or an encounter with a large pothole, be certain your new wheel is suitable along with your present bike setup in a number of areas.

To start out, know that wheels are front- and rear-specific and you will need to match street tires to street wheels and mountain bike tires to mountain bike wheels. Then, search for the next:

Tire Dimensions

Take a look at the sidewall of your tire to seek out the tire dimension that can correspond along with your new wheel dimension.

On street bike tires, you may see a quantity pairing reminiscent of 700×23. The primary quantity (700) is a dimension which roughly corresponds to the outer diameter of the tire in millimeters. The second quantity (23) denotes the precise tire width in millimeters.

On mountain bike tires you’ll see a quantity pairing that appears like 26× That is the approximate outer diameter (26″) by the width (2″). Different typical mountain bike tire sizes are 27.5″ or 29″; different sizes exist, however these are the commonest.

So long as your tire diameter (700, 29, and so forth.) and wheel dimension match, most tire widths will match. On the extremes—extra-wide tires on extra-skinny rims, for instance—a tire may not match. Some wheels checklist a variety of suitable tire widths.

Tire Kind

When you have a conventional clincher tire (the commonest tire kind), your tube’s valve kind, Schrader or Presta, should match the opening in your wheel’s rim. If it doesn’t, you’ll want a brand new tube.

In case you are utilizing tubeless tires with out tubes, you’ll need tubeless-compatible wheels (and tire sealant). Many mountain bikers use tubeless tires and a rising variety of street riders are attempting them. You possibly can run tubeless tires at decrease tire pressures for a smoother journey and higher traction with out pinch flats.

UST (common system tubeless) designated wheels make it simpler to mount tubeless tires. (Word that you could run tubeless tires with tubes, so when making your new wheel selection, you may contemplate tubeless-compatible wheels merely to provide your self the choice to attempt tubeless tires sooner or later.)

Tubular tires, utilized by some elite riders, are one other less-common tire choice that should be glued to a rim particularly designed to be used with tubular tires.

Brake kind

Do you have got rim brakes or disc brakes? Rim brakes require a wheel with a flat rim sidewall that can align with the floor of your brake sneakers. When you have disc brakes in your present wheel, your new wheels additionally should be disc-compatible, proper right down to the kind of rotor, which is the perforated ring that circles the wheel hub. Most disc brakes have a rotor that attaches by way of a 6-bolt mount, whereas some Shimano wheels use a rotor that has a centerlock mount.

(Left to proper: Rim brake with wheel eliminated; rim brake with wheel; disc brake with rotor.)

Axle Attachment

Does your wheel connect to your body with a quick-release skewer or a via axle? You’ll have to be certain your wheel is suitable.

A quick-release skewer slides by means of an axle that matches into the dropouts (slotted body ends) on both facet of the wheel. The wheel is held in place whenever you flip over the skewer’s lever, tightly clamping the wheel into place.

You possibly can inform you probably have a via axle as a result of that axle has to slip by means of two body holes, certainly one of which is threaded, to be able to connect the wheel to the bike. (Word that some bikes use a skewer on one wheel and an axle on the opposite.)

Axle Dimensions

Axle diameter: When you have a via axle, you’ll have to know the axle diameter. Widespread examples embody 12mm (street entrance, and mountain rear), 15mm (street entrance and mountain entrance) and 20mm (mountain entrance). (As a result of quick-release skewers are nearly all 9mm, diameter isn’t a priority with a skewer.)

Axle size: Whether or not you have got quick-release skewers or via axles, you must know the interior distance inside the body the place the wheel mounts. Widespread examples embody 100 or 110mm (entrance) and 130, 135, or 142 (rear). Some wheels embody adapters to suit quite a lot of axle lengths.

Rear Hub Kind

This determines how your rear wheel engages with the cogs in your bike’s drivetrain. There are two predominant hub sorts:

Freehub: Discovered on most bikes, a freehub has a spline that exactly matches into the middle of your rear cassette. The cassette usually has a lock ring to safe it to the freehub. Your new wheel’s freehub should be suitable along with your cassette.

Threaded hub: Discovered totally on older 5-, 6- or 7-speed bikes, this sort of hub is suitable with a freewheel cluster, a set of rear cogs that attaches by the use of easy threads. This type of hub will settle for any kind of threaded freewheel cluster.

Upgrading Your Bike Wheels

Typically ignored when riders improve their bike, a greater set of wheels can assist you considerably increase efficiency.

The entire compatibility issues mentioned for wheel substitute additionally apply to a wheel improve.

And, even when you don’t plan to do a tire improve on the identical time, you must examine your previous tires to make certain they don’t want changing.

Listed here are among the elements that have an effect on bike wheel high quality and value:

Higher supplies: Ultralight, ultrastrong carbon-fiber rims can provide a leap in efficiency and sticker value in comparison with most alloy rims. In comparison with alloys, carbon might be fashioned right into a wider vary of shapes whereas additionally providing superior energy and stiffness. This lets wheel designers create lighter, stronger or extra aerodynamic wheels with the identical or decrease weight than they will obtain with alloys. Remember, although, that carbon wheels with rim brakes might be slicker within the rain and run a lot hotter on lengthy downhill sections than rim-brake alloy wheels.

Higher bearings: Bearings don’t influence efficiency a lot till they begin to wear down. When that occurs, your wheels flip much less effectively. Once you improve to a better high quality, pricier wheel, it’s going to seemingly have higher, extra sturdy bearings.

Higher hubs (on rear wheels): You possibly can take pleasure in higher pedaling effectivity and larger sturdiness. A wheel with sooner hub engagement—that means your crank travels a shorter distance earlier than the drivetrain kicks in—will make your bike extra responsive.

Selecting Bike Wheels for Efficiency

When upgrading your wheels, you’re in all probability on the lookout for wheels which might be lighter, stronger, extra aerodynamic (or a mix) based mostly on the kind of driving you do. These charts present among the key areas affected by particular options of your wheels:





Lighter wheels: These repay whenever you’re climbing. Lighter wheels decrease your general bike weight, that means you expend much less power to maneuver. A 200-gram financial savings over your present wheels can present a noticeable efficiency increase.

Weight placement on the wheel may have an effect on the efficiency of the wheel. Wheels with a larger share of their weight on the rim are more durable to get transferring. Alternatively, wheels with much less of their weight on the rim and extra of their weight on the hub, will really feel extra responsive.

Stronger wheels: For some forms of driving, energy trumps low weight. Street wheels for commuters and touring cyclists have to deal with heavy hundreds and excessive mileage.

A stout set of wheels is a should for downhill mountain biking, which includes aggressive driving and large jumps. Fortunately, elevate entry makes it simple to move heavier wheels to the highest. All-mountain driving, the place descents are earned by climbs, requires wheels which might be each gentle and powerful.

There’s no common spec for energy, so you must pay shut consideration to clues within the wheel names, materials properties and development particulars. A better spoke rely makes a wheel stronger. Crossing spokes additionally will increase energy, with spokes that cross extra instances rising a wheel’s energy much more.

Extra aerodynamic wheels: Even at speeds as little as 20mph, minimizing wind resistance begins to pay massive dividends. So, for all sorts of street driving, from cruising to criteriums to century rides, upgrading to extra aerodynamic wheels is smart.

You don’t have to spend hundreds of for full-on disc wheels. Subtler options like a deeper rim profile—that means the sidewall of the rim is taller—enhance aerodynamics, as do bladed spokes. Search for “aero” in both the wheel identify or the product options. Remember, although, that any aero wheel might be harder to deal with in a crosswind.

Wider wheels: Prior to now, skinnier wheels and tires had been thought of extra aerodynamic, however air-turbulence research in recent times reveal that wider tires don’t essentially encounter extra wind resistance. Wider tires provide a typically extra comfy and extra forgiving journey—and so they really encounter much less rolling resistance—so the development is to go wider as of late.

Most wheels will settle for a variety of tire widths. However when you determine to run wider tires, it’s additionally price contemplating wider wheels for a greater match. When you go along with considerably wider tires, you’ll have to be certain they’ve sufficient clearance inside your bike body, too. Ask a bike-shop knowledgeable when you’re contemplating considerably wider tires.

Bike Wheel Upkeep

Wheel truing: Truing a wheel includes reshaping it to be completely spherical, eradicating any bends and tightening all spokes to the right rigidity. Wheels needs to be true out of the field, and wheel truing is a part of a typical bike tune-up. Except you believe you studied one thing is off otherwise you hit a extremely massive impediment, you don’t have to have your wheels trued extra typically than your common tune-up schedule. In case you are an everyday bike commuter, have your wheels trued extra typically, and have your bike maintained extra typically.

Wheel repairing: In case your wheel is tweaked somewhat than worn out, you possibly can have the store restore it. Carry the wheel in and the store workers can assist you determine if restore or substitute is the higher choice.
