The Weinmann DP18 rims have a 30-mm profile and acceptable weight, with stainless-steel spokes and double aluminium walls. This rim doesn’t have a machined braking wall. The braking wall is painted and compatible with mounting brakes. It is a pretty, elegant wheel, halfway between classical edgeless rims and more aggressive, wide-edged rims.The DP18 model is competitively priced. The size is 700c, meaning it is compatible with all road-bike tyres. You can mount 23, 25 or 28 tyres and will need a 48mm-valve inner tube. And it is crucial you mount a rim strip between the tyre and the inner tube to reduce or prevent punctures.
