Back to the old school
Basso is Italian, and as such it still very much believes disc brakes are for countries where it rains, hence an identikit Diamante is also available with rim brakes (£2,699 frameset).
Aero gained
The Diamante SV takes the same geometry as the Diamante Disc but gives it an aero facelift and arguably a more compliant ride due to narrower tubes. Tyre clearance goes up to 32mm (£3,899 frameset).
