Great Carrera Vengeance bike bought just over a year ago. The frame size is recommended for people between 178cm and 185cm tall. The bike worked fine until I decided to replace the chain but now will not work until a new cassette has been fitted and maybe a new chain-set because the cassette has worn with the old chain. The issue is that the chain slips under load due to not being stretched like the old one. However the new chain is fine and is a brand new Shimano chain worth £16.99 which will work nicely when a new cassette (and maybe chain-set) is added.
