Andrew, interesting review. I don't know if this is on my short list for off road bars, but looks really cool for my commuter. Price looks decent too. I have a question about the larger sweep bars. I bought one of those SQLab 12 degree sweep bars. I only rode it a couple times when I was having problems with my wrist. The wrist definitely felt better, but my shoulder kinda hurt after. It could have be due to something else; did you have an adjustment period with your shoulders (or other bits)? I kinda feel like that was due to the effective reach being reduced on a bike that was already shorter than I had been riding.
One more question. Do you normally increase your stem length with increased sweep bars? To try to get the grips in the same position?
