Hi all. I built out my fist real TT bike on a 2017 Cannondale Slice frame. I got everything on the cheap, but all parts are very good. My wheels are DT Swiss ARC 1400 "Dicut". I have DA brakes, pedals, shifters, and cassette. Only my brakes are 1015 (rim) and the crank is an "off-tier" RS 510. It's got solid crank arms and is heavy, but is rock-solid. It got it thinking it was an Ultegra crankset, and kept it because its 165mm. I switched the large ring to a 52T 105 ring. Other than that, I have an Ultegra FD and a Tiagra RD (I'm not a hierarchy snob and I needed an RD that would function best on a 10 speed cassette in friction, which happens to be the Tiagra.) I'm much faster on this bike than on any of my road bikes, at least in a straight line. But am I missing out of some real performance changing speed with such a build? A competitor I know swears that his brand new Quintana Rood is way faster than his circa 2016 Canyon.
