Attention, a rear derailleur (Shimano Deore 10-speed) and a chain must be purchased. I sell second-hand Merida One Forty B trail bike. The bike still works well, but as you can see from the photos, a rear derailleur (Shimano Deore 10-speed) and a chain must be purchased. Some scratches on the frame as you can see from the photos. Ideal for those who want to start trail biking or for those who repair bikes.   You can find the technical data sheet of the bike here: https://[hidden]/bikes/2014/merida/one-forty/2014-merida-one-forty-1-b/ On the bike there is: "Shimano Deore" crank "Shimano Slx" brakes "Fox Evolution Series" fork "Stamp" pedals "Ascend" saddle lever "Maxxis" tyres "Merida" frame M size   For any questions, please do not hesitate to contact me.
