When I go on a ride with other roadies- I use my Boreas Ignis. It is the most expensive bike I have and the best. One thing it does not have is "Bling" In comparison to any other bike- it looks nothing. You have to know bikes to realise the quality of the bike- the ancillaries and the wheels. If someone is going to take your bike--it is going. You just have to make it awkward for them and one group I ride with carries a Long Brake cable with a Joining link. Cable is linked through the bikes and the link is done up with an allen key. Just a normal cable joiner but I have never seen this type before. Lightweight and effective enough to deter the opportunist scumbag.
