I am selling my, as new ,Giant Defy 4 Road Bike. Size Medium=50.0 I bought the bike in August 2015 and have only ridden it once. The sole reason that I am selling my bike is that I am looking at getting myself a Sports Hybrid with a more upright position for commuting. Anyway about the bike. It's a Giant Defy 4 2015 model in white. As I have explained the bike has only been used once and that was only a quick spin round the block. This is my first road bike for over 30 years and wow what a revelation. It is so light and stiff and is seriously quick. The bike spec is as follows: Product description Quick and compliant, the Giant Defy 4 is a versatile endurance road bike that is built to go the distance. With a more relaxed riding position than a pure race bike and features designed to reduce fatigue, long distance riding will be a pleasure. The Advanced-Grade carbon composite fork - the same as on the Defy 0 - helps to reduce ?road buzz? and the OverDrive steerer design ensures precise steering. The ALUXX aluminum frame, stiff yet compliant, is also designed to reduce road vibration while maintaining efficient power transfer through the pedals. An FSA chainset with Shimano Claris gearing offers effective 16 speed gearing with a wide range to suit all terrain. Whether you are looking for a bike to take on a long weekend ride, a fast commute or even a sportive the versatile Giant Defy 4 is a great choice.
