Amazing how the weight limit is dropping – will be interesting to see what UCI does for weight limits.

This Rose X-Lite Team-8800 custom-made bike weighs in at a claimed 4.95kg. It would cost £4,768 in this build.
The frameset is sub 1,200g, according to Rose, and it is built up with a SRAM Red groupset, Ritchey bars, stem and seatpost, and a Selle Italia SLS Kit Carbonio Monolink saddle.
In its standard version it comes with Mavic R-Sys SLR wheels. However, if you want the super-light configuration shown here, you have to pay a surcharge for the AX-Lightness wheels.
