I am looking at a used SL6 Expert with Udi2 thru my LBS (demo bike) for 4500 or going with an SL7. The only SL7 available is the Rival AXS and my shop will be getting them in in about 2 months.
My issue is I currently have a 2018 Cervelo R3 with UDi2, a stages left side power meter and DT Swiss 1400 spline wheels and I love the Di2. The SL6 has Di2 so I could keep my power meter and just swap my wheels on to it. I would need to get the Aerofly II bar installed. Not crazy about the paint scheme on it. It’s the blue and purple camo. There is a part of me that likes the simplicity of the SL6 over the integration of the SL7.
The SL7 has Rival which I am really interested in trying plus it’s something new to try. It’s heavier and a new “ecosystem” yet I’m already within Shimano. I would need to get the Aerofly II bar installed and want a new cassette and a new crank to take some of the weight off which increases the overall cost. I really like the white paint.
The SL6 is 4500 and the SL7 is 4800.
Not sure what to do here.
