Bars came with my DF5. Going from 40cm Easton carbon track bars (yes I'm old) to these was easier than I thought -- I feel great rolling on the stayers line riding the tops, in the drops, and on the faux-hoods in more of a pursuit position. Be ready to get a longer stem though if you are going from wider bars.

Wondered how hard it would be to drop down to 33cm bars but it wasn’t an issue and they are so comfy to ride with.
