    I have the 45-700 on my bike and am considering going down to the 38-700 to gain some speed.

    How is it for you with the 50s?

    Some more details on this.

    The wheels are Specialized Terra C. The tires are WTB Venture 700×50. I have a 11-51 cassette mated to a GRX 812 rear derailleur modified with an XT M8000 derailleur cages for that mullet set up. With a 42t chainring, my gear range is wider than [Campy Ekar 10-44 cassette with a 38t chaining](https://kstoerz.com/gearcalc/compare/?link=1&&unit=0&lbl=1&tsid1=23&cogs1=10,11,12,13,14,15,17,20,23,27,32,38,44&rings1=38&tsid2=23&cogs2=11,13,15,18,21,24,28,33,39,45,51&rings2=42).
