I'm picking up my new Carrera Virtuoso racer from Halfords tomorrow afternoon. Someone on here said something to the effect that the bike was good but that you couldn't always guarantee the quality of the build. When I ordered it the chap in store said it would be checked over and if there were any problems to bring it back in. Anybody know what I should be checking for? I'm sure any problems with the gears or if the chain keeps coming off will be obvious, and I will be sure to check that the brakes work before I set off. Is there anything less obvious that I should look out for?
