I'm contemplating replacing the stock wheels on my Surly Cross-Check. The shop owner is a master wheel builder and recommended, like many others the Mavic OP/Ultegra combo. I also asked him about a DT Swiss TK 7.1 wheel with Onyx hubs (I can run either 130mm or 135mm spaced hubs - kinda nice to have that many options).
Does anyone have experience with the TK 7.1s and/or the Onyx hubs. Would I gain anything strength wise over the OP/Ultegra setup? I'm leaning towards the TK 7.1 option because I don't ride just smooth pavement, but I'm often bombing down alleyways riddled with potholes and curbs.
