Astral Wheels with SON Hubs

Gravel in depth

Astral Wanderlust Aluminum wheels on SON Delux Disc hubs

Our gravel pick from the Astral and SON parts we build with. The Astral Wanderlust Aluminum is a hooked aluminum rim, 24mm inside, 30mm deep, about 450 grams in 700c, sized for about 35 to 50mm tires. We lace it to SON Delux Disc hubs (front wheel) in 24 hole.

• Tubeless setup with a floor pump. Astral profiles have a deep center channel that helps the tire mount, and a bead seat sized for easy inflation and a secure fit. Astral says that lets you seat a tubeless tire with a pump at home.
• Bearings that need nothing from you. SON uses SKF ball bearings sealed on both sides and lubricated for life, which it says run many tens of thousands of kilometers with no adjustment. All SON hubs carry a five-year warranty.

Astral Back Bone Aluminum wheels on SON 28 Disc 6-bolt hubs

Our mountain pick from the Astral and SON parts we build with. The Astral Back Bone Aluminum is a hooked aluminum rim, 32mm inside, 20mm deep, about 535 grams in 27.5 inch, sized for about 2.4 to 2.8 inch tires. We lace it to SON 28 Disc 6-bolt hubs (front wheel) in 32 hole.

• Asymmetric gravel and trail rims. Astral's ASYM rims set the spoke holes off center, and it says this improves spoke tension balance by up to 30 percent. Astral credits that design for added stiffness, strength and longevity.
• A generator tuned to how you ride. The SON 28 is SON's all-purpose choice, with strong output even at low speed, including for charging devices. The SONdelux is lighter with lower mechanical resistance for fast riders and small wheels, and it gives up some output below 20 km/h.

Astral Radiant wheels on SON Delux Disc hubs

Our road pick from the Astral and SON parts we build with. The Astral Radiant is a hooked aluminum rim, 19.5mm inside, 32mm deep, about 495 grams in 700c, sized for about 25 to 32mm tires. We lace it to SON Delux Disc hubs (front wheel) in 24 hole.

• Delta shaping on road rims. Astral's road rims borrow the Delta profile from sister brand Rolf Prima. Astral says the added width and sidewall shape reduce wind buffeting and give the tire more support in corners.
• A generator with its coil in the center. SON uses a claw-pole generator with the coil placed centrally and carefully made sheet metal parts, which it says keeps losses low when the lights are off. It works without gears or contact, so SON says the generator itself does not wear.
