Where to Buy Mountain Bike Parts and Accessories

Whether you like to shop in stores or online, the popularity of this hobby/sport gives you plenty of places to buy components and accessories. The only problem is finding mountain bike parts for the brand that you happen to own. A lot of times you have to buy components that are specific to the manufacturer of your cycle otherwise they won't be compatible and it will be a waste of your time. In this section you will be provided with a couple of the best resources to consider using for 4 of the most popular brands.

Cannondale Mountain Bike Parts

This is one of the most respected MTB companies on the market. They have been around since 1971 and started out as a manufacturer of backpack for camping. In 1983 they began producing aluminum racing and touring frames with MTB frames coming soon after. Cannondale mountain bike parts are top quality and are made in the USA, Pennsylvania to be exact. Over the decades they have introduced a number of full suspension (soft tail) and hard tail models such as the Gemini, Prophet, Scalpel, Rush, Judge, Perp, Chase, 29er Caffeine and the Taurine.

There are a few websites you can buy Cannondale mountain bike parts from. Amazon actually has a decent selection and so does, and a couple of other websites. Most of these places will only have a couple of Cannondale mountain bike parts to choose from so you'll probably have to visit each one to make sure you get the best selection possible.

Mongoose Mountain Bike Parts

Here is a company that is so popular that you can find them in any Walmart or Kmart all across the country. In fact it may have been these stores that made them so famous. Of course, it probably didn't hurt when they merged with Pacific Cycle in 2001. However they got their reputation, Mongoose mountain bike parts are naturally very highly sought-after by hundreds of thousands of people.

You can often pick from a halfway-decent selection of components at stores like Walmart, Toys 'R' Us, and a few sporting goods stores like MC Sports and Sports Authority. There are a few random websites here and there that have a small selection of Mongoose mountain bike parts for sale but eBay is probably your best bet when you shop online. If all else fails, you can always call their hotline at (800) 626-2811 and figure out where a dealer location is near you.

Trek Mountain Bike Parts

It doesn't even matter if you're into MTB, just about everyone has heard of this major manufacturer. There are over 1,700 dealers across North America, Europe, Asia and distributors in 90 countries around the world. Headquartered in Waterloo, Wisconsin, and birthing in 1975, the vast majority of Trek mountain bike parts are actually manufactured in Taiwan and China, but that doesn't mean anything because this company is world-renown for being top-notch in nearly any aspect imaginable.

Pretty much any cycle shop will more than likely have some Trek mountain bike parts for sale like seats, rims, chains, sprockets, frames, forks and handlebars. You may also be able to locate a couple of websites that have a small selection to choose from. Chances are with a company as big as this there will be more sites with components than other brands that aren't as reputable.

Mountain Bike Parts

Shimano Mountain Bike Parts

This Japanese manufacturer of cycling components, fishing tackle and even snowboarding equipment was founded nearly 90 years ago and have been producing high-quality road, hybrid and MTB cycle components like drivetrains, brakes, wheels and pedals the whole time. Shimano mountain bike parts are some of the best that money can buy and they actually make up 75% of the company's sales income. In fact, this brand is so popular that they are considered a leader in the global cycle component market where they claim an estimated 50% of the market share.

One of the reasons Shimano mountain bike parts are so top-notch is because of the STI, which is the company's "Total Integration" gearshift system that combines braking and gear shifting controls in the same component. This makes shifting gears much easier because you don't have to remove you hand for the handlebars, unlike the down tube shifting systems that were most common before the STI system was introduced.

It can be rather difficult finding replacement and aftermarket components for this brand in North America, and your best best is probably to shop online. There is a website called that has the largest selection Shimano mountain bike parts available. Here you can buy gear cables, chains, sprockets and cassettes, pedals, shifters, brakes and brake cables and even all kinds of smaller components like brackets and inserts.
