Well, it's been, uhhh, a few weeks since the last post. Much has happened since then, including a lot of work, that has taken up much of my time. The Impulse has actually been together for most of those weeks--sorry!--but first, a photo of the completed frameset:
This was one of the build photos I took (below). Most of the 'cast' (components) shown are on it, but a few had to be switched out. The Grand Prix 4 Seasons radially trued/mounted great, and it was
very tight as far as clearance all around--particularly the under-brake-caliper region, and in the case of the 9000/6800/5800 era (and newer) of brake calipers, the specifying of a 28mm tire maximum is not conservative. For whatever reason, the front GP tire had a side wobble to it that had it brushing the inside of the fork blade (also a 28mm max tire scenario). So sadly, I had to switch those tires out for my true-25mm 700x25 Vittoria Corsas. The DA9000 brake calipers felt spongy from the lever, which I took as these were going to be pretty grippy. I decided to save them for another build. I did sneak one 9000 component on there, the front derailleur, and it looked quite at home.
