I'd recommend you try the Nokon outers (similar to the Jagwire alligators, but the links are smaller so the bends can be tighter) if you are going to keep the Yokohama's - they are compressionless and will take a sharp bend - I have done what you've done on my wife's bike as a temporary measure (shimano Cx calipers) and although it worked, it was starting to eat away at the caliper so very slightly (it was paint rub and it may not have gone further, I have to admit) - but again, that is just me being OCD, if yours works just ignore this. Btw, the bike looks fantastic.

I put down the deposit yesterday, and for the moment the people at Dean are being just fantastic - I mentioned I was going to race the Rad this October and they even asked if they could speed up the build so I could use the Dean for the race - 10/10. Told them no need, btw, I felt it was going to be hard to get the frame in and dialed by Labour Day weekend so I'd rather be patient than rush it and get something wrong.
