Singletracks Mountain Bike Podcast

Ryan Gaul is the Trek Factory Racing DH team manager and technical director. He’s been at Trek for about 10 years and is based in Madison, WI. How close to stock do DH and enduro riders run their bikes? Which aspects of a bike are modified to suit track conditions, and what stays the same for every race? Do World Cup racers take many risks when it comes to equipment, or are they pretty conservative? Is it common to run test parts, or prototypes in races? Is it difficult to convince athletes to try new components on their bikes? What type of race information is useful for product designers at the brand? How do you collect and communicate that information? How many spare parts/bikes do you bring to a World Cup race for each athlete? Are most athletes pretty involved in working on their own bikes? What’s the most stressful part of a World Cup weekend for you? Keep up with the Trek Factory Racing team at racing.trekbikes.com.

We're re-sharing one of our favorite episodes from 2022, so be sure to listen in case you missed it! Check back next week for more another fresh episode. In 2006 Goat and two friends set out to ride mountain bikes from Alaska to Tierra del Fuego, the southernmost tip of South America, and after three and a half years of travel, the trio completed the mother of all bikepacking trips. Riding the Spine is just one of many adventures Goat has experienced over the years, including living in a tree house and building and working on countless bikes. In this episode we ask: How did you upbringing influence your adventure-based lifestyle? How did you get into cycling, and particularly long-distance riding? What was it like living in a treehouse for 4 years during college? How did the idea of Riding the Spine come about? Who was in the group? What was your bike setup at the start, and how did it evolve during the ride? Why did you and the crew get arrested in Arizona? Which sections were your favorites to ride? Have you been on any bike adventures since the trip? Do you have any planned for the future? Get more stories from Riding the Spine at ridingthespine.com and keep up Goat's latest adventures at wandergoat.com. Cover photo by Melinda Thompson.

Lennard Zinn is a bike designer and frame builder based in Louisville, Colorado. His shop, Zinn Cycles, offers "a full line of semi-custom and off the shelf bikes for riders from very small to very tall and everyone in-between." He’s also the author of Zinn and the Art of Mountain Bike Maintenance, one of the world’s best-selling guides to mountain bike repair. In this first-half of our podcast discussion, Zinn talks about drivetrain maintenance, focusing on chains and lubrication. Later in the show we talk about the benefits of big 32-, 36-inch, and 750d bike wheels and designing bikes for riders both tall and small. Understanding bike chain wear and elongation 0:00 Chain wear is caused by dirt and oil-based lubricant sticking to the chain, creating a grinding paste that wears down the rollers, bushings, and pins. Zinn describes how the chain's inner links are made. The chain's flexibility increases as the bushings and plates wear, affecting shifting performance. A chain's lateral stiffness is crucial for proper shifting, and a worn chain can cause skipping during shifting. Chain elongation and its effects 6:46 Zinn discusses how a chain's elongation affects its performance, particularly when the distance between rollers exceeds the half-inch standard. He explains that a worn chain can misshape the cassette's teeth, leading to skipping and poor shifting. Chain checkers can be used to ensure the chain's length is within spec to prevent cassette wear. Lubrication and its impact on chain wear 22:35 Zinn explains that a dry chain will wear faster due to friction, while lubrication helps reduce wear but can attract dirt. He discusses the differences between factory lube and other lubricants, noting that factory lube is designed for machinery, not for low friction on the bike. Zinn recommends using a cleaner to remove factory lube before applying chain lube. He introduces the concept of chain waxing, which involves immersing the chain in molten wax to create a low-friction, clean-running chain. Zinn shares the benefits of chain waxing, including reduced noise, lower friction, and longer chain life. Chain waxing process and benefits 35:43 Zinn describes the process of chain waxing, including the need for a clean jar of mineral spirits and denatured alcohol for cleaning the chain. He mentions the cost-effectiveness of chain waxing compared to replacing chains frequently. Wheel sizes and their applications 1:03:20 Zinn discusses the advantages of larger wheels for tall riders like 32-, 36-inch, and 750d wheels, noting that 32-inch wheels can make a bike look proportionally sized. He explains the challenges of using larger wheels, such as increased weight and the lack of suspension forks. Zinn mentions the development of new carbon rims and tires for larger wheels, which could improve their performance and weight. Barber asks about the feasibility of using suspension forks with larger wheels, and Zinn confirms that rigid forks are the only option. Challenges in designing bikes for small riders 1:16:58 Barber asks about the challenges of scaling bikes for smaller riders, and Zinn explains the limitations due to the need for certain components. Zinn highlights the importance of proportional design, where larger wheels can make a bike look more proportionate for tall riders. He discusses the ergonomic issues for small riders, such as wider Q-factors and shorter steerer tubes on forks. Zinn mentions the UCI's weight limit in road racing as an example of how smaller riders are often disadvantaged. Modern trends in bike design and their impact 1:18:46 Zinn highlights the shortening of steerer tubes on forks which can be a problem for taller riders. He discusses the trend of wider rear ends in modern bikes, which can be detrimental to smaller riders due to increased Q-factor.
