The gear calculator is an excellent place to answer my question, Kai. Thanks. My switch from a 40t chainring to 44t (4.7-5.1, or an increase of .4 gain ratio) was roughly the same as the difference in gain ratio difference betrween 165 to 175 (5.1-5.4, or an increase of .3 gain ratio). In other words, I’d need to use a 41t chainring for the same ride feel, and that’s a significant loss of either power when climbing or speed when descenting. I’ll likely stick with the 175s, but may go with a 170 and split the difference. Grin. Great suggestion, Kai!
