This is a great bike, and is generally considered the best entry level road bike on the market
full spec and reviews on the decathlon website (it won't let me post the link here unfortunately!) the frame size is 48.
I am only selling as it is slightly too small for me
It would be great for a young teenager or smaller adult (I'm 5'3").
Pretty much as new, it's only done about 30 miles.
Text or email me if you are interested, as it is at my mum's house so I would need to check with her when she is free for you to go and have a look.
