Road endurance
Trek Domane SL/SLR Gen 5
2026 · 700c wheels · 6 sizes
Fifth generation of Trek's carbon endurance road bike, with clearance for tyres up to 40 mm. The Domane SLR (900 Series OCLV carbon) and Domane SL (500 Series OCLV carbon) share one geometry table, so these numbers apply to every SL and SLR Gen 5 build and frameset. Gen 5 moves to letter sizes (XS to XL). Trek uses a 53 mm fork offset on XS to M and 48 mm on ML to XL, which keeps trail close to 62 to 63 mm across the range. Stock tyre, stem, bar and crank sizes are from the Domane SLR 9 Gen 5 build.
