Mason SLR
2025 · 700c wheels · 8 sizes
Italian-made Dedacciai steel all-road super-tourer from Mason, paired with the RangeFinder AR carbon fork (398 mm crown height, 50 mm offset). Mason quotes clearance for 700x45 tyres without mudguards and 700x40 with them. Stand-over and trail are quoted with a 700x35 tyre on the 48 cm and a 700x38 tyre on the other sizes. Mason's chart lists the 62 cm trail as 5.1 mm, which is clearly a typo (the 60 cm, with the same head angle and fork, is listed at 65.1 mm), so that value is left blank here. Stem, bar and crank sizes are Mason's recommended per-size build components.
