Australian composites specialists Partington Advanced Engineering have an all-new aero carbon road wheelset, mixing materials & rim depths for a surprisingly light weight of just 1150g. Developed over the last five years, the mid-depth disc brake wheels lace alloy hubs to carbon rims with unique carbon spokes, balancing stiffness with low weight.
The Partington 39R/44R pairs a more blunt-nosed 39mm deep front rim profile to a deeper V 44mm deep rear that they say together optimize aerodynamic behavior in wide-ranging wind conditions making the wheels solid all-rounders.
The rims are said to be made over a PMI foam mold with a mix of high & intermediate mod carbon, plus aramid fibers with a UV-resistant resin. Internal rim width is 21mm (26.5mm external) and Partington have chosen to use a hooked-bead tubeless rim profile adherent to Mavic’s UST standard for consistent & reliable performance with a range of tubeless road tires – optimized for 25-30mm tires.
