• Should I switch my rear wheel on my 80s steel fixed TT bike from an open pro 32 spoke to a halo aero-track because I have it and it might be more aero, or should I ignore that and go with style and matching wheels?

    Additionally I can borrow my brother's 50mm U-shaped carbon rimmed front. 80s grey anodised open-pro style or aero gains!?

    It's a 25 mile TT with about 150m of climbing.
