The brifters and derailleurs are Ultegra 6600 taken from my last build. I love this groupset, really durable and clean looking. The only thing I don't like is the derailleur cable routing isn't under the bartape, but aside from that it's everything I need. I have a new big ring on the way, the gear ratio I'm going to be using is 44/36 front with a 12-27 in the rear. During the summer I may use an 11-25 and maybe a bigger front ring when I'm likely to be going faster, but winter riding is going to be 90% hard trails and singletrack in rough conditions and not too much smooth fireroad flying. For pedals I got some Crank Brothers Egg Beater 1s, first time trying these, I went with them for ease of clipping in and out and they are light/high quality at a low price point. I don't have enough use with them yet to give an opinion but they seem solid, I'll do a review in the future.
I cabled it all up with a Jagwire Racer cable kit, aside from the rear derailleur where I used a bit of Nokon housing for added durability. For bar tape I used Salsa Dark Brown Gel Tape, which looks awesome along with the faux leather Charge seat. It felt a bit smooth to me at first but after riding with it I like it a lot, I never wear gloves and it felt plenty grippy even when wet and caked with mud, and it didn't retain water either which is important. In part 2 I said the wheels were likely to be temporary, and although they survived a few rides 24/20 just isn't enough spoke count to handle what I'm using this bike for. I grabbed a 36h Chris King laced to a Mavic Open Pro for the rear, and a 32h White Industries hub which I will lace up in the next part, along with some other finishing touches and initial impressions. Unfortunately I must force myself to just look at the bike for the next few days as I have a race this weekend, and it's near impossible to ride this thing in a safe manner. After that though I have some death rides planned that will really put the Cross Check through it's paces.
