Wheels, your bike needs them. Try to ride your bike without wheels; you’re not going anywhere fast. Tracklocross is a style of cycling that doesn’t have many off-the-shelf options, especially if you want to run wider tyres. One of the best options is to always be a friend of your local bike shop and either get custom wheels from them or get them to tell reps to let companies know that you want tracklocross wheels. Indeed I believe this is why Halo now do an off-the-shelf option.
