Discover the engineering and chemistry behind tubeless technology and more with Stan's (NoTubes) President Mike Bush, whose industrial manufacturing background shaped ~25 years of cycling innovation. Bush explains the technical details of bead seat geometry, the science of sealant particulate systems, and how CT scans of mounted tires revealed the "bead float" phenomenon that caused early tubeless failures. Learn about the development of ExoCor valves designed to address sealant compatibility issues with traditional Presta valves, the chemical reaction that makes Dart puncture plugs work instantly with Stan's sealant, and the biodegradable formulation using natural latex that sets Stan's apart from petroleum-based competitors.

The technical discussion extends to the WPL product line, featuring USDA-certified bio-based lubricants derived from food science research, suspension oils meeting marine industry standards, and innovative dry chain lubes using ethanol solvents and specialized esters for clean operation. Bush shares insights into third-party testing protocols, manufacturing tolerances critical for tubeless success, and the engineering challenges of creating products that work reliably across diverse riding conditions. Whether you're a suspension technician, bike mechanic, or technically-minded cyclist, this episode delivers the deep technical knowledge behind the products that revolutionized mountain biking.

Rider safety takes precedence in this essential bike shop secrets episode, where bike industry veteran Dane Higgins addresses the critical question every mountain biker faces after a crash or component failure: "Can I ride it?" Learn the definitive protocols for assessing carbon frame damage, from the professional coin tap test to identifying dangerous stress points that require immediate replacement versus repairable damage. Understanding the difference between cosmetic carbon scratches and structural compromise can literally be life-saving, especially when dealing with handlebars, steerer tubes, and other critical load-bearing components.

Mechanical reliability directly impacts rider safety, making proper chain and cassette maintenance more than just a performance issue. This episode reveals how worn chains on new cassettes create dangerous skipping conditions during hard efforts, potentially causing crashes during climbs or sprints. Additional safety topics include quick link failure modes and reusability guidelines, proper helmet replacement after seemingly minor drops (4-foot falls can compromise protection), and the heat-related degradation affecting both safety equipment and carbon components in desert riding conditions. Emergency trail repair techniques using duct tape and zip ties provide backup solutions when mechanical failures occur far from help.

Tired managing batteries, firmware updates, and paying for expensive electronic drivetrains? This episode with SRAM's Jimmy Nordloh goes deep into the new Eagle 90 and Eagle 70 mechanical transmission systems that deliver transmission's shifting performance without electronic complexity.  The new mechanical transmission uses the same cassettes and flattop chains as the wireless transmission systems but use a traditional cable. At ~$670 and ~$490 respectively, these systems are for riders who want transmission performance without the heavy price tags, apps, or batteries.

SRAM has also standardized on mineral oil across their entire brake range (including the new Motiv brakes), eliminating DOT's moisture absorption problems while providing better lubrication and system longevity. Additionally, a completely redesigned Reverb AXS B1 dropper post increases reliability and reduces cost by switching to a simple air-over-air system that's easier to service and more reliable long-term. With 250mm travel options and improved tire clearance, this dropper solves fitment problems on small frames and includes a "Ride Active" feature which SRAM says… “provides beneficial suspension characteristics during technical riding without compromising pedaling efficiency or proper bike fit”.  Do you agree?

In this comprehensive deep dive, Shimano's Mountain Bike Product Manager Nick Murdick reveals a copious amount of details about their new XTR M9200 Di2 wireless groupset. Learn how Shimano engineered their first fully wireless mountain bike drivetrain with on-board derailleur batteries, customizable shifter paddles, and rock-impact protection designed from "the rock's perspective." Murdick explains the technical innovations behind the wedge-shaped derailleur design, dual-click shifting mechanism, and why Shimano chose derailleur hangers over direct-mount systems for maximum trail durability.

Discover the complete XTR M9200 component lineup including new brake technology with updated hydraulic fluid, 160mm crank arm options, and both long-cage (10-51) and short-cage (9-45) cassette configurations. Nick shares insider development stories, addresses SRAM transmission comparisons, and explains backward compatibility with existing Shimano components. This episode covers everything from battery life expectations to trim mode functionality, making it essential listening for mountain bikers considering wireless drivetrain upgrades or mechanics working with the latest Shimano technology.

Update! Nick Murdick got back to us after the recording with the answer to a question he wasn’t sure of at the time. 

Here’s the answer… 

It is indeed possible to convert a derailleur between short cage and long cage at the shop.  If you connect to e-tube project through the PC you will see an option to change between GS and SGS. The derailleur uses a different shift pattern for each cassette.  In some gears you may notice that it breaks the shift into two steps in order to use the shift ramps on the cassette more effectively. It's more noticeable when double shifting.
