David Folch is the founder and CEO of Dirty Sixer, a boutique bike builder focused on fitting tall riders with big wheel bikes. The Dirty Sixer line currently features gravel, all-road, and electric bikes, and will soon include a mountain bike with 32" wheels.

• How did your brand Dirty Sixer get started?
• How tall do you have to be for a 32er to make sense?
• What are some of the MTB geometry challenges involved in designing around 32" wheels? Does anything get easier in terms of fitting tall riders thanks to the bigger wheels?
• Has tire availability limited the development of 32" wheel bikes up until this point?
• Are any current MTB forks designed to fit 32" wheels?
• You hinted that you're working on a full-suspension mountain bike with 32" wheels. What are the challenges involved in designing a bike like that?
• Will a 36er mountain bike ever be viable in terms of tire and fork availability? 
• There are several comments on your Instagram posts from people who are against the idea of a mountain bike with 32" wheels, seemingly because this would represent another standard. Do you think 32" wheels will ever gain significant traction like 29er wheels did in the early 2000s?
• What's next for you in terms of big wheel mountain bike development?
