Enigma Esker

2026 · 700c wheels · 11 sizes

Handbuilt titanium gravel frame from Enigma's Signature range, made to order in Sussex from Reynolds 3Al/2.5V tubing, with clearance for 700c or 650b tyres up to 50 mm. Enigma offers 11 stock sizes named by effective top tube length in centimetres, plus a full custom geometry option. It is sold as a frame or as a custom-specified complete bike, so there is no single stock build.
