As of 2023 (our 60th year in business), Park Tool makes over 500 products and sells them in over 70 countries. We outgrew the back of the bike shop some time ago, and currently operate out of a 100,000 square foot facility just a few miles down the road from where the old Schwinn store once stood. We are firmly established as the tool brand of choice in bike shops and race pits around the world, and our reputation as the standard of the industry has even expanded to our repair help tutorial content, which has racked up millions of visits to parktool.com and over a hundred million views on YouTube, in addition to the hundreds of thousands of copies sold of our Big Blue Book of Bicycle Repair. We continue to update and improve our product line according to the demands of the industry, and have made a concerted effort over the past decade to bring more of our manufacturing in-house than ever before.
