Round-tube philosophy
Basso deliberately uses round tube shapes at the BB and head tube for higher torsional stiffness without extra weight.
Closed: Tuesday 27 October through Sunday 1 November. Please note: the workshop is from now on also closed on Thursdays.

Everything you need to know about the Basso Diamante
How the component works, which specifications matter and what to watch for when choosing. From the basics to the details real bike nerds care about.
Frame weight760 g (size 53)
Lower weight helps on climbs and repeated accelerations. For flat rides, commuting and carrying loads, comfort, durability and aerodynamics often matter more than a few grams. Frame, wheelset and complete-bike weights are not directly comparable.
CarbonToray 40T/30T, FAW 50
Material affects weight, stiffness, maintenance and use, but construction matters just as much. Do not choose on a carbon or metal label alone. Racers prioritise weight and response; everyday riders durability, protection and upkeep.
Tyre clearanceUp to 32 mm
More clearance gives options for comfort, grip and rough surfaces. Choose a supple road tyre for smooth tarmac, or more volume and suitable tread for gravel. Mounted width also depends on the rim; Thomas checks the combination and safe clearance.
Sizes45-61 (7 sizes)
Stack and reach help define riding height and length; wheelbase and steering geometry affect stability and agility. Racers often want a lower position, endurance riders more comfort. Do not compare sizes by name alone; body measurements and a fitting matter.
Seatpost2 setback options, 3B Clamp System Gen II
Bar width, stem length and adjustment shape grip, position and control. An aggressive position can support speed only if you can sustain it comfortably. For long rides and commuting, fit comes first; integrated parts can offer less adjustment.

Basso Diamante geometrie en constructieWhat should I check before fitting the Basso Diamante?
Tyre, rim and frame must fit as a combination. Mounted tyre width can differ from the sidewall size. Thomas checks clearance and the exact version before assembly.
