Alloy TCR with Ultegra 6600 and Ksyrium Elite wheels weighs just over 8 kilos. Will replace the alloy bars with carbon, carbon/alloy fork with a full carbon one and some nicer KEO blade pedals. And that’s about it for weight saving. Frame is 1400g, the same weight as my former Ti Merlin with Centaur. Target would be 7.3 kilos. But it does include a 20g power meter now.
Rider needs to shed a little too (11st at the moment)
EDIT: and since we are weighweenying, the Elite wheels don’t require rim tape, and the tubes are 50g Continentals. Tyres are Mavic, about 200g each. There is only one bottle cage and I’ve just bought a carbon 28g Bonty one. Normal saddle is a Flite Ti, but I also have the carbon shell of an old SLR with Ti rails that weighs only 130g.
EDIT2:
Ultremo ZX to replace my Durano S
saves only 100g in total. Same as the tubes.
EDIT3: My low-grade steel fixed wheel Kona Paddy Wagon road bike is 9.8 kilos with full SKS mudguards and custom wheels. That’s lighter than stock and feels great.
