I run a Kinket on mine. I simply disconnected the brake light wire for the time being and wrapped it. I'll drill a hole in the Kinekt post at some point down the road.
What exactly did MTB make for you? I ordered a set of 650bs (same front size as yours), so I’ll have to have them make likely the same thing!
Assuming this is the part?

About to order the Redshift. With the 4.0 SL, the faceplate has the light adapter if I recall. Can you use the Specialized faceplate and light adapter on the Redshift itself?
I am in the same boat. Very curious to see what others recommend. No chance that a non-EQ version can fit a 700x45, right? I know the 700x42 would rub fenders. But without fenders, I am wondering if a 45 is a possibility.
