My time trial bike

Here’s a pic of the bike I built up for time trialing. I’ve been using the frame a couple years now – first as a road bike, then last year I got the aerobar/saddle/rear disc and this year I got the front wheel. Even though it has a 74° seat tube, the zero setback seatpost and forward saddle position effectively make it 77° – plenty forward. The one thing I’m not quite satisfied with is the aerobar – the arm rest cups are made of plastic (one broke earlier this year and it was a real b!tch getting a replacement), and the extensions aren’t quite long enough when I’m riding the nose. I like the downward sloping wings though – good for my frame since the head tube is taller than a typical triathlon/TT frame, and also it gives me a lower more aggressive position for any hard, out-of-the-saddle efforts. Vision Tech makes a sloped wing integrated bar that has alloy arm rests (which should be more durable) and also offers extensions of different lengths, so I’m considering it as a replacement. There are lots of other good integrated models on the market (HED, Profile, etc.), but most of them have flat wings. Plus, most are made of carbon instead of alloy – I don’t know, I just can’t see paying $500 or more to save a measely 100g on a TT bike that sees mostly flat/rolling terrain. It would look flash, for sure, but I think an alloy bar that has great aerodynamics and the ideal configuration for my frame makes the most sense. Anyway, here’s the build:

    Looks fast just sitting there. Unfortunately all I saw of it was a blur.
