Ah Switzerland, I'll be near Geneva June 2016 for a bike race in Annecy, France. Can't wait to visit Zurich for a couple of days.
Anyways, the Spacers will definitely allow more room away from the UC arm. I can't confirm how the 55 will fit but overall size wise it would fit with no problem if you use the Spacer I'm using. You will just need to have an ARB or TJM to prevent rubbing on front wheel well
What other companies make spacers and do we know who makes the "best" ones?
