Enigma Echelon Rim
2022 · 700c wheels · 11 sizes
Handmade grade 9 3Al/2.5V titanium road frame built in Sussex, designed for endurance riding, shown here in its rim brake version with standard single bolt caliper brakes, quick release axles and clearance for 700x28 tyres. Enigma names each size by its horizontal top tube length in centimetres. The frame is sold on its own or as a frameset with Enigma's own C-Six carbon fork (an Enve fork is an optional upgrade), and custom geometry is available at extra cost; these numbers are for the standard geometry. Enigma does not publish fork offset or trail for this bike. The offset used here (44 to 45 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.
