SCR-058c 580g
A performance sculpture that's lighter than anything else!
Fully hand-made here in north Italy by passionate techincians and engineers.
Reaches an astonishing performance-to-weight ratio thanks to the proprietary MIF carbon technology and our time consuming wrapping technique.
No shortcuts!
Top tube flat-oval section blends into steer tube with a nice fin that sensibly helps to point the apex of hi-speed turns with laser precision.
Generously dimensioned downtube ensures torsional rigidity by the log of its wide round section
Beefy tapered chainstays feature progressively increasing lamination layers, this translates into livelier reactions under acceleration
Crank and fork bearings contact the frame through precisely cnc'ed AL7075T6 fittings that fully void looseness or squeaks
Seat-tube enlarges its section while descending, then widens up at the BB area, all laminated with tricky twice progressive layering
Downtube flattens at bottle cage fittings and widens up to oval at the BB shell to keep crank loads under good control
Top tube and seatstay merge just right where FEM analysis suggests they should in order to manage well the sprinting stresses
The extreme reduction of stress riser areas is from the beginning the base of Extralite's engineering philosophy
3D dropouts: these tiny cnc sculptures can withstand to countless QR opening & closings, that unlike the commonly used carbon dropouts
Additionally the SCR dropouts offer a truly solid fitting of the rear hub-axle and wheel plus the rear derailleur bolts on very safely too
Stay tuned!
