Here goes then. These are how the sks raceblades long are fitted to the Triban....and don't judge my photography skills.
Here you can see the metal clips that fix inside the brake calipers. These are the only bit that go under the brake so no rubbing or clearance issues.
Then you simply snap on the plastic guards onto these metal clips
Then it's a case of pulling out the spindle and pushing them through the eyes on the guard arms
It's all very simple. I've had the guards on and off quite a few times and they go back on easier each time. Due to experience I guess. You've no need to remove the clips from the brake calipers, they'll just sit there and cause no bother. And there was no cutting involved, in my case anyway.
And here's the bike fully guarded up
Hope the pictures help, I know theres always lots of queries as to which mudguards fit the Triban or any bike really.
I would definitely recommend these sks raceblades long.
