2017 Ritte Vlaanderen Carbon Road Bike - XL (59cm frame) I have owned two of their frames over the last 6 years and they are as good or better than Trek, Giant or Specialized frames with very unique paint jobs. I am 6'1" 200 lbs - makes for a great first Road Bike or Fall/Winter training bike. Ritte's Vlaanderen chassis is extremely rigid, but at the same time comfortable. It is ideal for those looking for maximum performance on the road, performance guaranteeing the perfect balance between speed and agility that does not compromise stability. The frame is made of high quality Toray carbon and boasts a BB30 bottom bracket, as well as an oversized chain for greater power transfer.
