Effective top tube is 54.5cm. Barely ridden over the last few years. Frame and the white paintwork is in excellent condition. The Di2 is out of battery and I don't have a charger so you will have to source a new one which can be easily found online. The charger hasn't been replaced since the bike don't get ridden much.
Saddle not included but is negotiable if you want it. Happy to answer any questions.
