that is a good question...
What did I learn and what I would do next time:
-The "under" top tube routing I chose wasn't the best. When you go to grab your bike to hike your bike for whatever reason the housing stop and cable makes it uncomfortable to carry for long periods of time. I would change it so that it is at the top of the top tube.
-I would increase the length of the head tube so I wouldn't use so many spacers. I had thought I liked the front handle bar super low, but now I like it with a few spacers
-I would then use the new Chris king InSet headset
-I would also make the bottom bracket slightly higher. WHen you go over logs, the bottom bracket glances the log
-The rear shift cable/housing is broken up into sections. It runs along the top tube with no housing, then goes to housing to clear the seat tube, then back to no housing along the seat stay to the derailleur, where it goes back into housing. I should've just make it one continuous piece of housing from the seat tube to the derailleur.
-Lynskey now offers an industrial brush finish instead of their higher cost shine brushed finish. I would have gone with that, but they did not offer that.
-As for components.... the cycle king ebay saddle was too stiff. I now have a Selle Italia SLR. I also had to get rid of the EC90 setback seatpost and now have a Thomson masterpeice
other than those things I have nothing else I want to change on the bike. I still think it rides amazing. Top tube length, and geometry is perfect for me.
