Enigma Echelon Road Disc
2022 · 700c wheels · 11 sizes
Handmade 3Al/2.5V titanium road frame from Enigma's Sussex workshop, shown here in its Road Disc version with flat mount disc brakes, 12 mm thru-axles and clearance for 700x32 tyres. Sized in 1 cm steps named after the effective top tube length. Enigma publishes a fork length of 370 mm but no fork rake or trail. The seat angle steepens from 72.5 to 76 degrees as sizes get smaller. Enigma does not publish fork offset or trail for this bike. The offset used here (39 to 41 mm) is worked out from Enigma's own stack, reach, head angle, bottom bracket drop, chainstay and wheelbase, which pins it to within a millimetre or two, but it is not a published figure.
