Hand-built in the UK. We build our Forza-C SON dynamo wheelset complete and ready to ride. This wheelset built with 28h drilling front and rear, Pacenti rear hub, Sapim D-Light spokes, laced two-cross to optimize strength and low weight. Hubs are configured as 12mm x 142mm rear and 12mm front hub with centre lock disc mounting. 

The SON 28 is a very capable hub and can run lights like the Sinewave which are also capable of charging your devices simultaneously.  

SON 28 is a hub dynamo universally approved for all wheel sizes from 16" to 29". The rated output is achieved in the 700c (622)-wheel at approx. 16 km/h (SONdelux at 19 km/h). Thus, SON 28 is recommended if a lot of light is required at low speed or when either device are to be operated or their batteries charged. 

Our Forza-C rims are the heart of this wheelset, and they are optimized specifically around tubeless tires. The inner width of 21 mm provides for more air volume (comfort) and improves tire profile (control). The asymmetric profile provides for good spoke tension when lacing to offset hub flanges. These rims are the result of a clean sheet design that brings our best thinking to the table on what a rim should be.

Equipped for the 2019 Tuscany trail.


Tyre pressure guide

NOTE: The Forza-C rim is designed for with tubeless specific tires only 

700 x 25 max pressure 100psi (6.9bar)

700 x 28 max pressure 90psi (6.2bar) 

700 x 30 max pressure 85psi (5.9bar)

We recommend you allow a sliding scale for tire pressures. As a general rule, the wider the tire is (more air volume) the less air pressure you’ll need to achieve a fast but compliant ride. Experiment with tire size and air pressures to work out the best combination of volume and pressure for your intended terrain and overall riding style. Air pressure recommendations from the tire manufacturers are a good starting point but should not exceed 105psi for this rim.

The Forza-C features a hookless, tubeless ready rim bed. As such, tires will require a firm grip to install, tyres will go on by hand with the proper technique. Once installed, the bead should be snug on the rim. If you feel the tire is ‘too loose ‘do not use it and find another type or brand to obtain the proper interface between tire and rim for a safe fit and reliable seal.
