your spending way too much on a commuter! you really don’t need anything as fancy. You’ll never be able to leave it unattended.
My advice, spend around £400 – £500 on a commuter, bank the rest.

It’s is more than enough for the job; Carbon fork, road gearing, 700cc wheels, rack mounts, simple brakes, takes mudguards, inconspicuous.
