3X Natl Champ Lauren Stephens
Lauren Stephens has been easy to spot in both Road and Gravel events; just look for the stars and stripes. She has won three US titles: two gravel and one road. Oh, but there's so much more to her career. How about more than 30 UCI road race victories? She has twice won the Joe Martin Stage Race, the Tour of the Gila and Unbound 100. Lauren has also raced Track, Time Trials, Mountain Bike and Cyclocross. Not bad for a former high school math teacher who wasn't a serious cyclist until 2008. In addition to reviewing her career, Josh and Hottie also talk to Lauren about her nicknames, her extensive bike collection, that interesting denim vest, social media and her new team -- Aegis Cycling -- and its approach to racing and social justice.

AJA #43: CRR/CDA and Hookless plus The Magnus Effect
We take a look at what has become a dilemma for some Marginal Gains seekers and that is optimizing aero, rolling resistance on a tubeless, hookless rim. Josh has an admittedly unpopular take on the subject. We also get into the aerodymanic idea known as the Magnus Effect. The principle says that a spinning object will develop unequal pressure on either side as it moves throught air. Josh expains how -- if at all -- the Magnus Effect, affects that rotating thing we love; the bicycle wheel. We also have questions on hot waxing in a vacum oven, the aero cost of external cables, and what is kind of a Silca product shocker: it's Ultimate Shock Pump.

AJA #42: Pipe Cleaners and Crack Baggies
We know, the title sounds like we're doing an episode about drug paraphernalia, but trust us, it's the (very good) answer to one of many great questions posed to Josh in this latest listener-driven Q&A episode. We get into using the right lube under the right conditions (including super dry moondust mountain biking), aero combos with the Conti Aero 111, TPU tube challenges, and much more. It's a fun and info-packed episode from the show that dares to say, "It depends."
