ProsLovely steel frame, many attachment points, rides well.
Have bought and built up myself this frame into a commuter bike. Was looking worldwide for a nice steel frame with ability to fit 28 plus tyres and mudguards.
For the price this frame is fantastic.
Looked worldwide for a steel frame with these features and found it here.
I love the many thoughtful mounting points for racks, fenders etc
