Rider and Wrench
I recently swapped an 11 speed XTR Cassette/RD/shifter from an older frame with a 68mm external bb to a new frame with a pf30 converted to 24mm with a wheels bb. With the 68 mm bb I was able to configure the bb spacers to bring the chainline in 2.5mm which greatly improved the chainline in the larger rings with the 2mm inset of the 11 speed cassette. I have been running 10 speed cranks with race face NW chainrings but due to the lack of adjustability of the pf30 bb I ordered a set of 9020 single ring crank but want to try either wolftooth or one up rings rather than Shimano for $$$ purposes. The wolftooth seems to keep the chainline in to 49mm and I think the OneUp does as well but wondering what experiences others have had?
