Sweet bikes…My bikes look like I have kids…because I do
With that said I run mostly 105 with Ultegra RX in the rear. I9 wheelsets, one for road and one for gravel.
Bike is a Niner RLT9 steel build. Tad heavy but it’s smooth and I love it.
I run the Panaracer Gravelking SK’s 38mm. Handle pretty much anything with those and gravelking slicks on the road 32mm.
