Fat Bike Parts

The following lists known fat bikes components and parts such as cranks, forks, hubs, rims, tires, tubes, etc.

Obviously, Surly is the most well known manufacturer of parts thanks to it’s Pugsley fame. But, they are not the only option.

Recently, fat bikes have seen a surge in popularity as they are not limited to snow biking. They are also great for adventure biking and having fun.

Many manufacturers have noticed the increased popularity trend as there are now over 70 different fat bike options available for purchase. See the article, Fat Bikes: Fatty Got Back, for a list of complete bikes or frame only options.

With an increased number of fat bikes, there’s also an increased number of manufacturer producing parts for fat bikes. Which is a good thing as more options and increased competition should lead to lower prices.

Surly parts are still the most widely available and always a good option. I like them. However, they are not locally available everywhere and they can be hard to find. As a result, online shopping may be the only option.

Anyway, there were over 25 parts manufactures counted, and over 70 products counted.

The following lists were composed on August 2, 2013.
