Took the tractor tires off my gravel bike, put a 14-30 cassette, took 2 chain links off.
I gotta tell you I love this bike. First because RT gifted it to me, also it rides probably second to my favorite Ironman, and it is so much Fun. I ride it only on our river walk...and the next gravel ride.
Those ultra II tires are 23s but they were 12 bucks each and brand new...so there's that.
This pic doesn't do justice to this awesome paint.
Changes hopefully coming soon.
