A finest quality 3AL 2.5V titanium frame, handcrafted in Great Britain here in Enigma's Sussex workshop. The Enigma Echelon is their latest creation and fills the gap between the best selling Excel and Evade models. Designed for fast endurance/sportive riding, the Echelon is beautifully balanced, very responsive and bestows awesome power transfer along with a forgiving ride quality to make it the perfect choice for distance riders. Echelon features carefully selected grade 9 3AL 2.5V double-butted titanium main tubes to shave off extraneous weight and the frame shares the same high-performance Ultra-Formed/Exogen rear triangle with our top of the range Excel. Echelon is a top specification titanium frame, made in Britain and sure to be a future classic.
