5 Things to Consider When Choosing a Cross-Country Mountain Bike
When you’re looking for XC mountain bikes, focus on the following areas when assembling your shortlist:
- Wheels and tires
- Bike geometry
- Seat post
Suspension design is arguably your most important consideration. Hardtails are typically favored over full-suspension bikes as they are lighter. Rear suspension adds weight that you could thoroughly do without when you’re snaking around demanding trails.
That said, you might want a rear shock if you plan to ride predominantly on rocky paths and trails with plenty of roots getting in your way.
The bulk of hardtails have a suspension fork with 100-120mm of suspension travel. You’ll get the same amount for rear travel if you opt for a full-suspension alternative.
When you’re considering which suspension platform would make the best fit, don’t forget that it’s all about what kind of terrain you plan to be tackling. Get this right, and you’ll find the right bike with ease. Get it wrong, and you’ll be making an expensive mistake.
2) Wheels and Tires
Next, give due consideration to the wheels and tires.
When you’re choosing between 27.5-inch wheels and 29-inch wheels, the dominance of 29er wheels makes your decision pretty easy. The vast bulk of XC bikes come with 29s.
What’s the benefit of larger wheels? Well, you’ll roll more readily over rocky terrain, and you’ll also find you can maintain speed more easily.
Carbon wheels are stiffer and lighter with the inbuilt benefit of being extremely responsive, too. There’s a price to pay for this improved power transfer and enhanced steering, so be prepared to dig deeper for carbon. Alloy wheels make a reasonable alternative, and they come in at a much better price point.
3) Bike Geometry
The geometry of your XC bicycle will dramatically impact the overall bike feel. This is another area of these bikes that’s changed quite significantly over recent years. Manufacturers are prioritizing aggressiveness and descending.
Slackness has not reached the point of trail bikes, but head angles are certainly slacker. While you can find the occasional 66.5-degree head, the standard head falls somewhere between 68 and 70 degrees. This set-up will help when the trail gets steep and technical while still providing the responsiveness you need to feel comfortable.
Seat angles are usually 74 or 75 degrees for traction and weight distribution.
Shorter chainstay lengths improve both power transfer and traction.
4) Seat Post
There’s little to fire up a healthy debate among riders than the issue of rigid posts vs. dropper posts.
If you opt for a titanium or carbon rigid post, this will shave off some precious weight, but you’ll pay the price when it comes to heading downhill. Unless you’re planning to get involved in some serious racing, the weight saving probably isn’t worth fussing about.
Dropper posts, on the other hand, might weigh very slightly more, but they make descending a whole lot easier.
The cockpits on XC bikes have evolved over time. Where handlebars were once incredibly narrow, these days, they have widened while stems have shortened. Why? Well, the modern configuration ramps up stability and keeps your weight nearer the front than the back.
Typical handlebar width on cross country machines is anywhere from 720mm to 760mm.
Standard stem length of 60mm is more in line with dedicated trail bikes or mountain bikes. With the largest frames available, this could nudge up to as much as 90mm.
What Is a Cross-Country Mountain Bike Used For?
As the name makes abundantly clear, the core purpose of these bikes is for riding cross country.
Although this is the primary use, many XC bikes are also designed to accommodate the needs of commuters, too. If you’re looking for this, make sure the bike comes with mounts for a rack and kickstand.
You might also ride a cross-country bike on a range of trails from fire roads to quite technical singletracks. If you’re competing, cross-country racing spans everything from short, gritty sections to hardcore endurance events.
When you buy a XC bike, and you’re getting a great deal of versatility.
Which Material Is Better for Your Bike? Aluminum Vs. Carbon
You’ll need to decide between an aluminum frame and a carbon frame when you’re scoping out cross-country bikes, but which material is best?
While you can still find steel and titanium frames, it’s aluminum and carbon that rule the roost in 2020.
Aluminum once reigned supreme, but carbon fiber has become far more accessible, so it’s vying for primacy.
Carbon frames give you all the stiffness you need without too much weight thrown in. The malleable nature of carbon makes from superb aerodynamic tubing, as well.
One thing to note with carbon frames, though—it’s tough to detect damage. That can lead to failure under stress when you very least need it. If you take a serious tumble, you should rigorously inspect your carbon frame afterward.
Aluminum frames are alloyed with another metal. You’ll pay less while the material is still pretty light and stiff. The major drawback of aluminum comes in the form of a harsh ride that not everyone enjoys.
How Relevant Is the Wheel Size for a Cross Country Mountain Bike?
How relevant is wheel size, then?
According to research , wheel size “does not significantly influence performance” when trained mountain bikers are riding cross country. It’s generally considered that “personal choice” is usually the reason for choosing one size wheel over another.
The good news?
With the dominance of 29ers, you can stick with that size and get solid cross-country performance.
