A hard road race is decided in two places: on the climbs, where every gram counts, and on the flats afterwards, where drag does. Most wheelsets favour one of the two. The Avalon SL5 Ninefold weighs 1134g and has a 50/55mm aero profile, so you don’t have to choose.
Ninefold is the top of the 9th Wave range: carbon spokes (Alpina Carbolite) and our own Onda-R hubs with ceramic bearings. Building our own hub gives us the freedom to set flange diameter and spoke count, which is what makes a carbon-spoked build like this possible. We chose 20 spokes front and rear, and not to save weight. In our tests, 24 spokes made the wheel too stiff at the expense of comfort: carbon spokes already add stiffness compared with steel spokes. With 20, the wheelset as a whole is better balanced: stiff enough for a sprint or a fast corner, and calmer over long hours on rough tarmac.
The rim is 50mm deep at the front and 55mm at the rear. The front wheel steers the bike, so a slightly shallower profile up front keeps the bike calm in gusts while still giving you an aerodynamic advantage. At the back, the air is already disturbed by you and the bike, so the extra depth adds little aerodynamic gain. What it does add is lateral stiffness from the rim itself, where it counts: when you accelerate and sprint. At 23.5mm internal width, the hooked, tubeless ready rim is rated for 27 to 33mm tires. For the best aero shape, low rolling resistance and high grip, we recommend 28 to 30mm tires. The ART asymmetric rim design evens out the spoke tension between the drive and non-drive side of the rear wheel, so the wheel holds its shape under sprint loads instead of flexing energy away.
This is a wheelset for riders who race and climb hard and want the lightest aero option we build. It is hand built in the Netherlands with rim tape and valves installed, and once you register your wheels, the carbon rims are covered for life. Read more about why the front and rear rims run different depths in our journal article. If you prefer steel spokes and DT Swiss 240 hubs, take a look at the Avalon SL5.
