FWIW I managed to just about get 650x47 WTB senderos in to my CDF frame. I have bugger all clearance either side of the tyres at the chainstay, but extending the dimples is apparently an easy modification which I’m getting done at some point.
I've chatted to Pi at Clandestine who seemed to think it's a pretty easy job. If he can essentially extend the existing dimples a little further to where a 650b tyre hits, it'll be plenty of clearance for my needs (5mm+ each side)
