Not surprisingly given the big product launch this week, Dave and James have a lot to dive into with SRAM’s new Red AXS wireless road groupset: what’s different about it, what’s not so different, what’s been improved, and what’s stayed the same – and the thing everyone will invariably ask us, whether we’d choose that or the latest Shimano Dura-Ace. We also chat about the neat features embedded into the new Hammerhead Karoo GPS computer, and the significance of the new tire partnership between Zipp and Goodyear, Dave gets his thoughts about road bike cockpit reach off his chest, we choose our favorite tubeless plug kits, and we’re still worried about loose headsets.

Your bikes have secretly been getting longer, and no one told you

Much leaked and recently teased, SRAM has now officially unveiled the latest iteration of its Red AXS road groupset. This top-tier offering introduces a new approach to shifter ergonomics and braking, along with a number of other smaller changes. Shile at the product launch, tech editor Dave Rome sat down with a few key members of SRAM’s road product and engineering team to discuss what’s new, what isn’t, and why. Following the chat about new SRAM things, Dave then sat down with the team from Hammerhead to discuss the equally new Karoo computer. You can also read our thoughts (and see photos) of these new products over at escapecollective.com. This deep dive is a bonus episode of Geek Warning podcast.

Bonus ep: A deep-dive with SRAM on new Red AXS

We know, we know, it’s been ages since we did our last Ask a Wrench episode – late January, in fact. Guilty as charged. Better late than never? But as a nice bonus, our panel of geeks had an extra-long list of repair and maintenance questions to answer this time around, like why bedding in your new brakes is important, what not to do with your fancy digital torque wrench, how to diagnose a curious front-end clunk, how to protect your fancy new bike for the long haul, the best way to fix a paint chip, and much more. Fair warning: The full episode is only available to Escape Collective members. Head on over to escapecollective.com/member to support this show and everything else on our podcast network.

Bonus ep: Ask a Wrench is back!

Welcome back to Geek Warning! This week, James and Dave have a varied conversation covering tech related to road, gravel, and mountain bike. The Giro has begun and Tadej Pogačar took a little tumble that many were quick to blame the equipment for. James and Dave discuss that such finger pointing was not warranted this time. At the opposite end of UCI disciplines, the conversation then turns to aero gains returning to professional downhill mountain bike racing. In the tech new front, the geeks praise Chris King’s new Gen 4 hubs and discuss why Forge+Bond entry into the road market may not be hugely successful. Plus there’s discussion of a new Bike Yoke dropper, Zwift’s price rises, and more. Meanwhile, a new Shimano Di2 patent has surfaced teasing wireless 13-speed shifting. Dave got Terry of BetterShifting.com on the phone to discuss the discovered patent and what it may mean. Our pick one this week is perhaps better described as a buyer’s guide to selecting a wheelset for gravel. From rim choices, to spoke choices, to hub choices, you’ll hear what our geeks prefer for their own bikes.

Wireless 13-speed Di2?

The Sea Otter Classic just wrapped up literally a few days ago, but clearly someone forgot to turn off the tap of new bikes and gear. Cervelo just announced a redesign of its ultra-popular Aspero gravel bike, and clearly put a lot of thought into what needed to change – and perhaps more importantly, what didn’t. Colnago also just dropped a new gravel bike of its own, the G4X, and Giant finally revamped its Trinity TT bike – no more rim brakes! Dave and James also chat about the eight billion tubeless valve stems out on the market, our favorite mountain bike computer mounts, and some of the latest happenings on the industry side.
