Thanks Tony- overall it was a pretty good experience working with MIke Kone on the stock frame. He took the time to respond to emails carefully and spent time over the phone talking about specifics of the bike. Before the Boulder, I was riding a Rawland rSogn. He asked what I liked about it and didn't like about that bike. Honestly, I couldn't really complain too much about the rSogn, at 190 lbs the fork seemed sufficient for what it was intended to do and the bike planes super well for me. I was looking to add a frame to the stable that was intentionally built for 650Bx42 and after seeing the quality of a friends All-Road I was sold. Mike did mention that weight wise, I was between the skinny and light OS tubesets. I opted for the light OS for added shimmy resistence though my skinny tubed rSogn didn't shimmy at all with the Miche headset. He said it would be stiffer than the Rawland but not by much. My assessment- the light OS All-Road planes just as well for me and its difficult to notice much of a difference while climbing. On descent, expecially on rougher roads, the light OS tubeset inspires more confidence and feels more planted and secure- think 20 mile loose gravel road descents in the Cascades.
He sent two sizes for review before locking down the order and went over the differences which was much appreciated- the smaller size better in the shimmy battle- the bigger size more comfortable over distances. One thing to keep in mind is when you want to recieve the frame- sounds like Waterford is usually ~2 months out. I ordered my frame in mid-january and recieved it mid-March. MIke and his team spends a day or so doing QA/QC before shipping it to the customer. Mike was happy to recieve follow up emails on the bike and when my local LBS had questions on build ie. routing the rear taillight wire and setting the nitto rack- Mike's team was more than happy to help. He has a wealth of knowledge with performance oriented frames which is shown in the latest generation of frames.
As for the taillight braze-on mount location- I too was concerned that it would too low but in practice, as long as the drivers sight line is higher than the light it will be seen. You have to be lower, perhaps on a recumbant to not see it.
All in all a good experience!
