Finally got pix of the tri bike. It's my former commuter, rain trainer, and magic gear fixie: an REI Novara Trionfo. I put on Profile bullhorns and Syntace aerobars. I kept the Ultegra brifters and just mounted them on the bullhorns. Looks a little wonky but works just fine. Supercomfy and well-broken-in Selle Italia Flite saddle on a Profile forward seatpost to replicate that tri-bike geometry. Rolf wheels.
