Selecting Bike Wheels for Efficiency
When upgrading your wheels, you’re in all probability searching for wheels which are lighter, stronger, extra aerodynamic (or a mix) based mostly on the kind of driving you do. These charts present a number of the key areas affected by particular options of your wheels:

Lighter wheels: These repay if you’re climbing. Lighter wheels decrease your general bike weight, which means you expend much less power to maneuver. A 200-gram financial savings over your present wheels can present a noticeable efficiency enhance.
Weight placement on the wheel can even have an effect on the efficiency of the wheel. Wheels with a higher share of their weight on the rim are more durable to get shifting. 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 sorts of driving, power trumps low weight. Street wheels for commuters and touring cyclists must deal with heavy hundreds and excessive mileage.
A stout set of wheels is a should for downhill mountain biking, which entails 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 are each mild and robust.
There’s no common spec for power, so it is advisable to pay shut consideration to clues within the wheel names, materials properties and building particulars. A better spoke rely makes a wheel stronger. Crossing spokes additionally will increase power, with spokes that cross extra occasions rising a wheel’s power much more.
Extra aerodynamic wheels: Even at speeds as little as 20mph, minimizing wind resistance begins to pay huge dividends. So, for every type of street driving, from cruising to criteriums to century rides, upgrading to extra aerodynamic wheels is smart.
You don’t must spend hundreds of {dollars} for full-on disc wheels. Subtler options like a deeper rim profile—which 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. Bear in mind, although, that any aero wheel may be harder to deal with in a crosswind.
Wider wheels: Previously, skinnier wheels and tires have been thought of extra aerodynamic, however air-turbulence research lately reveal that wider tires don’t essentially encounter extra wind resistance. Wider tires supply a usually extra snug and extra forgiving journey—and so they really encounter much less rolling resistance—so the pattern is to go wider as of late.
Most wheels will settle for a spread of tire widths. However should you determine to run wider tires, it’s additionally price contemplating wider wheels for a greater match. In case you go together with considerably wider tires, you’ll have to be positive they’ve sufficient clearance inside your bike body, too. Ask a bike-shop skilled should you’re contemplating considerably wider tires.
