New gravel wheelset BORG30 -1452g
The photos are quick ones better shots to come.
Gravel and XC MTB riding are similar enough that rims should be no different.
The BORG30 is light, stiff and fun to ride.
Wheelset weight with Sapim Force spokes and BORG DX hubs is 1450g.
The rims are tubeless compatible and hookless. Tubed tyres can be used but why would you want to. The internal width of the rim is 25mm. External width is 30mm.
Gravel wheels are not aero wheels. 40mm tyres put a kybosh on that so it should have round spokes. Also ditch the need for aero rims a wide shallow rim can be used. With the right profile this can still be radially and laterally stiff.
The hubs are 12mm thru axle compatible and reliable. They are made for centrelock rotors but 6 bolt adapters are available.
One important aspect of tubeless compatibility mean to me a tyre that will remain seated with no air pressure. The BORG30 passes that test. This means once a cut is sealed with tyre plugs or sealant you can reinflate with a hand pump. The wheel can be used with inner tubes but I can't think why you would do that to yourself.
