Thanks for the complements guys.
quick update; the bike has been riding great, I'm just shy of 300 miles on it with no problems to report.
Shimano 6870 is phenomenal. Shifts every time, crisply with no hesitation. Haven't had any chain drops or miss shifts to report, very impressed.
as for fit, I feel much more comfortable on the bike now than at first. I bought a -17 degree stem but haven't tested it out. The current setup has grown on me quite a bit.
There was a question about tire sizes and brake cable routing hope these images help clear things up. Peter says the bike can run 28's I'm running 23's now on 25mm width rims which equate to 17.5mm internal width. I think I could get upto 28's but not sure about snow spikes. Opps forgot to resize.
