Nope. Same size. For me those Donnelley’s took too much effort to maneuver and bring up to speed.
One other thing I did was I put an 11-40 XT cassette on. I feel like it loosened up the gearing some. It felt too constrained and road like with the 11-34. Gravel cyclist had a YouTube video where he shows that the GXR RD will in fact accept that size cog and I can attest that it does.
I love the bike! It’s fast and feels really good climbing and descending. It’s not the most comfortable gravel bike but if I wanted that I would’ve of gotten something else. It’s perfect for long adventures and going fast if you want.
Enjoy! And let me know if you do any mods to it I should know about.
