I bought the bike two months ago and I can prove it with an invoice. I have made an improvement by putting 50 profile wheels, a very good saddle and VELOMANN V50R wheels. COMPLETE GROUP SHIMANO 105DI2 12 SPEED (11-34). COMPACT CHAINRING (50-34). AERO HANDLEBAR (100mm). INCLUDED bottle cage, look pedals, bike computer support (garmin, wahoo...).
