This build used DT Competitions to lace Hope Pro4 hubs to WTB Asym rims, in this case a 650b (27.5″) wheelset. Asymmetric rims aren’t strictly new but the number and variety of models on the market is improving. The idea is simple — spokes land to one side of the rim instead of the centre. This counteracts the natural asymmetry in rear wheels, resulting in more even tension. I’m a fan.
