Raleigh Circa 2 Mens 2017 Hybrid Bike Raleigh Circa 2 Mens 2017 Hybrid Bike What are the exact dimensions (in mm) of seat tube and top tube of 16'' frame of this model (CR216MBK)?
The best I could find was Raleigh's own web site , and all they list is frame sizes and approximate leg lengths to suit.

If the supplier themselves don't list it, then you'll have to go measure one at a shop, or hope someone else here happens to own one and a tape measure.
