Using the 19'' with the 18'' rear works good and does give it quicker steering close to the 17/17 set. It will put more weight on the front endfor beter steering on-road. The 19/17 set keeps it closer to stock geometry which is still great to ride off-road, just not faster like the 21/18 can.
The one thing that's great about the 19/17 set is the amount of tire choice's they have, and the handling it has both on/off-road.
You could try the 19/18 first then see if it works good for you, and get the 17'' rear later if it's not working good for you.
hi..Woody chiming in,,,IMHO,,if it's real "canyon carving " performance your seeking,,, the 19/17 is far superior...it's two grinning thumbs up from all who've ridden/ experienced it...and all Zach shared is on the money,,,there are some who have been satisfied with the 18" rear
