'Taking a look into the wheel sets you are referring to, these are ones in which we don’t stock and are an older model, possibly oem, so there could be some differences and this does reflect in the pricing. They are also not disc compatible and do not have the new aero spoke as per ours.
We keep Shimano and DT, so the RS21 would be the closest match to our R24, although shimano use open ball bearings and DT use a sealed cartridge bearing.
Couldn’t say what in the other brand ranges would be best though.'
