The mudguards are the Chromoplastics P45. The rack is the Super Tourist DX. Not sure if it was disc specific or not.
Inspired by the wonderful look of your Boardman CX and the chat/ advice on this forum I went along and bought a Boardman CX with some SKS P45 guards to go with as my winter trainer.
Thanks to the pics you posted on here I was able to see how the P45s went on the frame. The instructions were useless no complete diagram or step by step easy installation.
Great guards though and ideal if youre going to keep the original tyres on the bike.
However...
I wanted to just point out that the way you have bent the stay actually negates a safety feature of the SKS P45 mudguard.
By bending the mudguard stay through the BB5 brake mount and not around means that should a large object get between the tyre and mudguard your stay mount will not disengage from the Secura clip and could cause you a lot of problems. Ie damage to guards, BB5 brakemount, wheel spokes and even injury to yourself.
I write this not to criticize just to help.
I did manage to bend the mudguard stay under the BB5 brake mount and still had enough length to trim at the top where it joins the mudguard proper.
I have tested the disengage Secura clip by pulling hard on the mudguard and can confirm it will release in the event of a jamming object.
I hope this helps someone. When I get home I will post a pic to show what I mean to help illustrate a bit better.
