Boardman 3XB PRO/DRC/3XB/SL Hybrid Large Pro 21". Carbon forks, Black - great condition and rarely used few scratches nothing major. I do hope the photos explain the details and features of my bike. I bought this bike as it came highly recommended by the retailer. My intention was to become fitter by riding along the local canal paths. However, we moved house and the bike has been kept unused in my house for over three years. I will not ride a bike on the busy roads. So, I thought someone else should benefit from this great bike. I am no bike expert. I am 5ft 7 ins and this size bike was advised for my height. The frame I believe is 21 ins or 54 cms and the front wheel is 26 ins.
