Allied Echo Review: Why 40mm Tires Change Everything

If you're shopping for an allroad bike right now, you've probably noticed the shift. Gravel bikes keep getting more capable—wider tires, more aggressive setups—but at the same time, tires in the 38–40mm range are getting fast enough on pavement that you can leave the road without really paying for it. In this video, I review the Allied Echo and break down why it’s built around that exact idea. With clearance up to 45mm (optimized for 38–40mm), a stable road-first geometry, and a build that prioritizes speed and adaptability, the Echo sits right at the center of where modern allroad riding is heading. This isn’t about pushing further into gravel territory—it’s about removing the penalty of leaving the road. I’ll cover: How the Echo rides on pavement Where it really comes alive off-road Why 40mm tires might be the sweet spot right now Who this bike is actually for And if you haven’t ridden a 40mm slick tire yet… you might be missing out. 📦 Bike Details Bike: Allied Echo Size: 56 Drivetrain: SRAM Red XPLR AXS (48t / 10–46) Wheels: Zipp 303 XPLR SW Tires: 40mm Goodyear Vector R Weight: 16 lbs 3 oz (no pedals) 💬 Drop your questions in the comments or DM me on Instagram 🌐 Website: https://outdoorbros.com 📬 Contact: chris@outdoorbros.com 👇 Let me know Where would you ride something like this—road, gravel, or both? 🔔 Subscribe More cycling reviews, builds, and real-world riding from OutdoorBros. 📋More info? https://alliedcycleworks.com/ 00:00 You Don’t Need a Gravel Bike Anymore? 00:25 What Is the Allied Echo (and Why It’s Different) 00:45 The Shift to 40mm Tires (This Changes Everything) 01:30 First Look: Lambo Bronzo Zante & Design Details 02:30 On-Road 03:12 Off-Road 04:11 Futureproof? 04:24 40mm Slick Tire 04:38 Who's it for? 04:49 Spontaneity #AlliedEcho #AllroadBike #40mmTires
