Recently did my first TT (duathlon), and already looking to go faster. Had four people pass me on bike portion, all in full TT setups, I was on my road bike (aero bike, but drop bars and alloy wheels). Without buying a dedicated TT bike, looking to make some changes so I can get a lil more speed out of my road bike.
It's a Fuji Transonic, which tested about the same as an S5 as far as aero goes, so not horrible. First step is to fix my position, so I'm putting a set of aero bars on. I have a cheap aero helmet that will do for now, and some shoe covers. San Remo speedsuit is coming as part of my team kit. I have a set of 46mm carbon wheels that I wasn't able to use for my first race, they are 28mm wide with 23mm GP4Ks, so decent aero and rolling resistance. Thinking about swapping in some latex tubes and TT tires for race days.
I'll work on my position, and do some races on the 46's for now, but looking ahead, if you had to pick one (I realize 88/disc would be optimal), which would be faster, 46mm up front and disc on the rear, or 88mm front and rear? The 88s would be 25mm wide, and I'd run a 20-22 tire up front (prob Conti Attack).
I'm thinking the aero gains of narrower/deeper up front would trump the gains of the disc in the rear, but I'm curious to see what those of you with more experience think, maybe someone has even run similar combos.
