this is what they say in short about the rs81's
Like the Zipps the rims on the RS81s are pretty wide at 20.8mm. We've seen a lot wider rims recently for a couple of reasons, It improves the aerodynamics of the tyre and rim combination because it makes for a smoother transition between the two, and it also makes the rim laterally stiffer, and the wheel stronger.
i have wider rims on my handbuilts and they do make for a nice comfy plush ride with 25mm tyres
I favour the 25cc size myself too..
