There's one hiding somewhere. Also fatty quit being a tard. Anyone riding a fixed rig on an undulating course would be much slower than an equal or worse rider on a geared rig. To efficiently climb you'd need a smaller ring on the front which = slower on the flats/descents, alternatively keeping a big ring up front you'd be using way too much energy and get a nice big lactic acid build up = slower on the flats/descents and tiring early.
