The two main types of mountain bikes are cross country mountain bikes and Trail bikes, but what’s the real difference between them and which should you be using? In this article I give you a bunch of tips for how to decide which bike is right for you.
Everybody starting in mountain bikes just pictures the one mountain bike used for everything. You could use a hardtail bike like the one above for both cross-country (XC) and trail riding, but it would a a rough ride taking a trail in a bike with no rear suspension.
Bike have many parts so let’s look at them now and what’s different between each type.
Bike Riding Terrain
Cross Country (XC) Riding
Cross-country bikes, or XC bikes for short, are generally ridden on forrest paths, smooth roads, singletrack (bike-width trail through the woods), and paved roads. XC riders generally prefer twisty trails and hills instead of the more mountainous paths that trail bikes generally go on. These riders do both short, intense races to longer endurance races. Generally speaking XC is more for speed than adrenaline.
Lately there are some cross country bike races that incorporate a bit more technical terrain than is classically part of xc. Over at singletracks.com there are some pictures from the World Cup Stellenbosch in South Africa and while it looks amazingly fun, they are still overcoming foot-tall logs and medium rocks. So XC riding can really vary but it still won’t go up to the multi-foot drops that trail riding is known for.
Trail bikes are used on forest paths, rough roads, jumps, good-size rocks, and generally anything that creates a little adrenaline. Trail bikes are more for conquering terrain rather than the simplest and fastest routes.
No matter which you choose, you’re going to be a bit away from civilization and you’ll want to be sure you have a backpack stuffed with all of the goodies like a repair kit to be sure you can get back if anything breaks.
Differences Between Cross Country Mountain Bikes and Trail Mountain Bikes
Because Cross Country and Trail bikes are designed to be used differently, there are differences in the design and parts used. It all comes back to what the bike is meant to handle.
One good way I’ve found is to actually look at some pictures and such for both xc and trail bikes and see which you just feel inside is right for you.
For cross country biking, over at Mountain Bike Review I found a great writeup by someone who recently went from road bikes to cross country and it has pictures and all of the reasons she loves it. It’s hard for me to put it any better than she does with 6 reasons why she loves xc riding.
Likewise for trail biking, over at Liftopia.com is a great post on 10 reasons to love downhill trail riding. As you can see, trailing riding can be a big more rugged but if big jumps and drops appeals to your adrenaline side, then trail riding might be right for you.
Or better yet, get both. Start with cross country biking to get your skills and stamina up, and then get a trail bike as an additional bike and enjoy both worlds.
Medium suspension travel of up to 4 inches for mild trails
The main goal is a light-weight bike.
The shorter travel leads to a more rigid ride and getting more power to the ground.
The front suspension is heavy-duty to handle the stress of jumps and rough terrain.
The front suspension travel can be up to 10 inches.
Usually the front suspension is an air spring.
Tail bike front forks may include a lockout to limit suspension travel.
Cross country bikes can either have a medium suspension of up to 4 inches of travel or no rear suspension at all (which is a hardtail bike).
The rear suspension can have up to 10 inches of travel.
The rear suspension may have a lockout to limit travel suspension either partially or totally. A total travel limit would let the bike act like a hardtail which has no rear suspension.
With a full suspension, a trail bike will absorb rough technical terrain. If the bike is a hardtail, the path through the terrain will have to be selected carefully.
Wheels and Tires
Most of the cross-country bikes have 29 inch wheels and tires under 2.2 inches in width.
XC bike tires are skinnier than trail bikes to lower the rolling resistance and thus makes the bikes go faster.
The tires can be either 27.5 or 29 inches although 29 inches is getting more common.
The tires are wider up to around 3 inches.
The tire are more knobby in general to help get better grip on slippery rocks for instance.
As these are built for speed, the rider leans more forward and down for aerodynamic reasons.
Trail bike riders sit more upright mostly because the rider needs to be very agile and shift their weight around to keep the balance of the bike.
Todays mountain bike frames are made of a wide array of both metals and composites. The four most common materials are carbon fiber, aluminum, steel, and titanium. Each materials has a different price and durability attach to it so cross country and trail mountain bike usually won’t have the same frame material.
Steel tubing is the most popular bike frame material. In the case of a trail bike, it’s desirable because of it’s durability and it costs less.
Cross country bikes need to be light in order to achieve top speed. Because of this, many cross country bikes are made of carbon fiber which has low weight and high strength if the buyer can afford the carbon fiber cost. If not, aluminum is the next most likely choice.
Trail bike frames are slightly different as well. Trail bikes tend to have more slack head angles which then leads to having the tires a little farther apart than cross country bikes.
While some of it is personal preference, there are some basic questions to help direct what bike fits your needs:
Is the mountain bike only going to be used on mild paths and roads?
Is the mountain bike going to be used on downhill trails with rough technical terrain?
Is the mountain bike going to be used on a wide variety of terrains?
What is your riding style?
If the bike is only going to be used on smooth surfaces like roads or mild trails, then the XC mountain bike is going to be your best choice.
If the bike is only going to be used on rough terrain for the thrill, then a trail bike is going to be your best bet.
If you are going to use the mountain bike on a variety of both mild surfaces but also rougher trails, then you’ll want a trail bike with front and rear lockouts for the suspension. With this, you can limit the travel so that on smooth surfaces you can waste less energy by limiting the vertical movements of the bike. On smooth surfaces, you want a less cushiony ride.
Sometimes a video will help to make it easier to watch a video than read all of the details, so here is a video I made just for this article.
Can You Turn One Bike into the Other?
This is a question I get quite often. Can you turn a XC mountain bike into a Trail bike or vice-versa?
XC bikes and trail bikes have different geometry, saddle position, and suspension (though you can limit the trail bike suspension to be a little better on only smooth surfaces).
What About Enduro Mountain Bikes?
If you look at an enduro mountain bike, you’ll notice it is very very similiar to a trail bike except it has a longer wheelbase due to a different head angle. Because of this, I am lumping it in with trail bikes for the high-level purpose of this article and to not over-complicate things.
I am a mountain biker among other things and I enjoy writing about both topics I know but also about new things about mountain bikes that I learn. If you enjoy tackling trails and tracks and everything in between, then this is the blog for you.
