This is a brand new Cervelo R3 2019 frame built up with used parts from an older Cervelo R3. The groupset is predominantly Shimano 5700 (105) with an Ultegra cassette. Used twice since it was built up by Broadstreet Cycles in July. Selling because I just had a second child and my riding time has gone from low to virtually non-existent.
