How to measure for a Mountain bike

Properly measuring for a bike is incredibly important and being comfortable matters to both professional and casual cyclists alike.

Mountain bikes come in standard sizes (S, M, L) that generally correspond to your height. Many bike manufacturers include size charts that list a height range for each bike size. (If you’re in-between sizes, it’s best to bit on the smaller side as more sizing accommodations can be made with a smaller frame than with one that’s too large.)

Having a basic understanding of bike geometry can also be helpful when comparing one bike to another or dealing with a specific fit issue. A few of the key indicators are:

• Effective top tube length
• Reach
• inside height
• Seat height

Online Shopping Tips: REI and most bike brand websites include sizing charts for bikes featured online. Look for listed Inside leg heights and compare that number to your inseam. The difference between your inseam and the Inside leg height should fall within the target ranges. (For example, if you have a 30” inseam, you’ll want a mountain bike with about a 28” Inside leg height.)

To measure your inseam: Gather a large hardcover book or notebook, tape measure and pencil. Then:

• Stand against a wall (with bike shoes on).
• Straddle the book, spine up, as if you were sitting on a saddle.
• Use the pencil to mark where the spine of the book meets the wall.
• Measure from the mark to the floor. This is your inseam.
• Repeat the measurement another time or two to make sure it’s accurate.

Mountain Bike Seat Height

When deciding if a bike fits you properly it’s important to have the seat height correctly adjusted so you can get an accurate feel for the bike. To check your seat position, ask a sales associate or friend to hold the bike upright while you step on the saddle:

Proper position for ascending hills and riding flat ground: With your foot at the bottom of the pedal stroke, you should see a slight bend in the leg, reaching about 80-90 percent of full leg extension. This helps you pedal efficiently and powerfully using your major leg muscles.

Proper position for descents: Lowering your seat lowers your center of gravity, which gives you better control and more confidence through steep descents. You’ll need to experiment with different seat heights to find what feels best but start by lowering your seat about 3 in. from the height you set it at for climbing hills and riding flat terrain.

Adjusting the seat height: Release the quick-release lever on the seat post (or use a wrench if there’s a binder bolt) and raise or lower the post as needed. Be cautious not to raise the post outside the “minimum insertion mark” etched into its side. (If you need to change the seat height that dramatically, you might need a different frame size.)

Retighten the quick-release lever or binder bolt before riding. (Be cautious not to overtighten the binder bolt. Use a torque wrench to tighten the bolt to the manufacturer’s requirement. Be especially careful with a carbon-fiber frame and/or seat post.)

If you expect to progress quickly on your mountain bike, you may want to look for bikes with dropper seatposts or consider adding one. These seatposts let you raise or lower the seat by pushing a button, helping you adjust instantly to varying terrain.

Fitting Women’s Mountain Bikes

Women often have uniformly slimmer shoulders and longer legs compared to their torsos than men, and women-specific bikes are designed to meet these needs. Women’s bikes often have narrower handlebars and shorter or more compact frame dimensions. Some women find that men’s bikes fit well and are comfy, but women-specific bikes may deliver a more exact fit for some.

Fitting Kids’ Mountain Bikes

If you’re buying a bike for a young rider, it’s easy to want one they’ll “grow into,” but it’s especially important to buy a bike that fits well so he or she can ride comfortably and confidently while learning.

Inside leg height: As with adult bikes, check the Inside leg height. Whatever the top-tube style, look for about 2″–4″ of clearance.

Seat height: Most kids’ bikes are designed so they ride in a more upright position. They should be able to sit comfortably, see around them easily and grip the handlebars with a slight bend in their elbows. Their legs should be slightly bent at the bottom of the pedal stroke.
