bars, stem, seat post - aluminium
saddle - reasonably light 225g claimed
fork - carbon with carbon steerer (Real Design)

I was surprised how heavy the whole thing came to. The frame is 2.8lbs and the complete bike came to 19.2 lbs (no bottle cages). Is this the sort of weight other bikes with 105 group, cheap wheels and non carbon components come to? How much lighter would an ultegra build be?

When I eventually replace parts I might do the upgrade if it makes a noteable difference in weight but I wouldn't change anything right now since the purpose was to use up spare parts. Just curious and surprised by the weight.

p.s no picture for the moment as I haven't put on the new tyres and bar tape. That'll be next weekend's task.
