I slapped this 28T Cult devotion gaurd sprocket with removed gaurd on yesterday and realized during my first test rip that my hypothesis of getting longer cranks to balance out the acceleration by increasing leverage is spot on as the 165s i got on crippled me with muscle inflammation after yesterdays travels.

Someone please enlighten me, I think I’m cooking up the best drivetrain for trail/street riders:
28T
9T
170mm
Cassette for reliable hub engagement and low maintenance, full link because I’m old school like that and understand metal tolerances and fatigue to a fundamental extent.
a lot of riders are all using bigger chainrings these days, 30, and even 33t isn’t uncommon, trails and transition guys make the use of the bigger ratio.
30/9 all day bb. 25t is pretty much unrideable now for me.
28 is a minimum I’d want to ride.
25 is fine for younger ones learning or park riders dropping in on 14 foot bowls to get some speed but most dirt/street riding 28 is the lowest i’d want to go personally.
27/9 with 175s. I’m a trail guy. My wheels slam perfectly in a 13.75 backend using a master link
I like 29-9. 25-9 is waaaay to east of a gear.
30/9 and 165mm cranks here. I like how it feels with high speed 180’s and a cassette.
With shorter cranks you actually use less energy to travel the same distance due to making a smaller circle as you pedal. You might get more leverage in the first 1-2 pedals when starting out with longer cranks, but at cruising speed I’m sure the crank length doesn’t make too much of a difference. Also, shorter cranks are stronger.
30/10 is my preference. Same ratio as 27/9 but smoother since everything is a bit bigger. Also chains last longer.
