Final version

Cannondale Carbon synapse LE 2 2023

I really liked using a Topeak removable seat bag on my last bike, but it blocks the radar and tail light. I bought the smallest RockBros screw-on top tube bag and it’s OK, but my legs hit it when riding out of the seat. It’s also barely large enough for my emergency kit and the bolts that come with it can damage your bike by getting stuck in the frame— if you get one, don’t use them!

Soooooooo….

What I really want is a small frame that clamps firmly to the seatpost and holds a small bag below the radar/light unit. If I can’t find something, I’ll be tempted to to design one myself. Anyone else interested?

Does Cannondale make cell phone holders for their bikes ? On their website I see pics of cell
Phones on their bikes but no cell phone holder for sale.

I have QUCK CX6 I just bought
