What in the upside-down world?","html":"","width":"100%","height":180,"duration":3535,"description":"Our necks are hurting from the whiplash of information regarding what tyres are actually fastest off-road. Ronan teases a fresh discussion he had about optimising one sponsored rider for Unbound and some surprising lessons that came from that. It's a topic that continues to fascinate, especially given some of the world's best cross-country mountain bikers have been racing Short Track on 50 mm gravel tyres.In addition to that, you’ll hear Dave Rome, Alex Hunt, and Ronan McLaughlin explain why none of them are currently choosing to use 3D-printed saddles. There’s a PSA for anyone with wireless shifting, and of course, there’s new stuff to talk about, too.As usual, members also get our Ask a Wrench segment, which this week sees Dave Rome and pro race mechanic Brad Copeland answer a handful of questions, including: how keep 11-speed shifting running long-term, understanding bike handling, and best practises for travelling with new SRAM Full Mount derailleurs (Transmission and XPLR). Members can submit new questions here.Timestamps:5:15 - Corrections corner related to 55 mm road tyres8:40 - Corrections corner related to the Zipp 303 SW naming11:00 - So mountain bike tyres aren’t always faster off-road?24:00 - DT Swiss joins the gravel suspension game29:30 - Why we don’t choose 3D-printed saddles42:10 - A PSA to wireless shifting44:30 - Polygon’s new Helios A road racer50:30 - Goodyear’s new Connector gravel race range55:00 - HED’s new gravel wheels58:30 - Ask a Wrench with Brad Copeland (member-only)59:40 - Keeping SRAM 11-speed going long-term1:05:30 - How to understand rear handling?1:09:00 - Travelling with SRAM T-Type/Full Mount derailleurs","thumbnail_url":"https://img.transistorcdn.com/RBvZ42VOa2IulzLpz6GqMhunUzl2KYbNT7_xuoZrdHw/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9iYzNk/OTc3NzE0MjIyOWM0/M2IzZDcwODY3ODU1/Njc5Mi5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
