reason	Trek publishes no defensible conventional equivalence for its letter sizes. Trek states it 'recently transitioned Trek road bike sizing from numerical sizing to alpha sizing' and now publishes height and inseam only. The centimetre figures retailers print beside Trek letters are per-model seat-tube lengths, not size names: the same 'M' appears as 47.6 cm on a Madone and 50 cm on a Domane, and 'S' also appears as 47.6 cm. The only cm-to-letter statement Trek makes is partial — the Madone Gen 8 FAQ says 'Sizes 52cm and 54cm have been combined into one size (M) and size 62cm has been replaced with a new XL frame' — which accounts for two of eight old sizes and leaves 58 cm and 60 cm unresolved between L and XL. Any complete mapping would have to be invented, so Trek keeps its letters and its retailer-printed centimetres are discarded rather than read as conventional sizes.

Its rugged OCLV Mountain Carbon frame with aluminum chainstays and seatstays offers a full 160 mm of travel front and rear thanks to the RockShox Lyrik fork and Super Deluxe Select+ RT shock, so even rough lines and nasty root sections lose their scare factor. You’ll also get a Shimano XT/SLX drivetrain with 12 reliable gears, powerful SRAM DB 8 four-piston brakes, a Bontrager Line Vario seatpost, and Tubeless Ready Bontrager Line TLR wheels that are ready for whatever you throw at them."
