I’ve typically used a 32 tooth chainring on my cross-country bike, but this year I switched to a 34 tooth and found the additional speed really helpful for Outside Workouts when I’ve “ran out of climb” on a route and had to hold power over a flat or downhill section. More recently I’ve been riding …

Ideally you should do a test fit. In theory you could do it with the same chain depending on the amount of slack and the amount of chain growth (if full suspension). My preference and recommendation would always be to drop the air out of the rear shock and measure at full compression.

[image] miro.rides.bikes: Do you use the same chain length? No, different chains. My 34 chain is too loose on my 32 chainring. I’ve never tried my 32 chain on my 34 chainring though.

I will give it a try, I don’t think the chain growth on my bike is that large, I ride a Supercaliber and the rear travel is not that long. Last week I adjusted the b-screw setting and noticed that there was no noticeable difference if the bike was at sag or not, so I gather it behaves almost like a …

I dropped from a 34 to a 32t for Leadville on my Supercaliber. In the 10T there was too much slack in the chain after the switch. It was “rideable” but it clearly didn’t look right with that much slack and I ended up taking out a couple of links. I haven’t tried going back to the 34T yet, so not …

On my Epic Evo with is doing double duty as trail and XCM bike I run a 30t chainring (the smallest ring compatible with the XX1 PM) and a Ingrid 10-48 cassette. I run a 32/10-52 Eagle on my Enduro and really hate the huge jump to the granny gear. Given that the long-travel sled is no climbing prodi…

What year Epic Evo? My bike came with a 32t chain ring, and in the 10x32 combination, there’s hardly a gap between the chain and the OEM chain stay protector. Would love to have the option of putting on 30t chain ring for days with multiple 20% climbs. Have been afraid it could end up acting as a c…

[image] blackbird1: I run a 32/10-52 Eagle on my Enduro and really hate the huge jump to the granny gear. That’s interesting. I used a mountain bike with a 10–42 cassette and a 28-tooth chain ring, and the only gap that I did not appreciate was from the 12- to the 10-tooth cog. My current m…

It’s a medium-sized Evo MY 2021 and although it is tight there is no „chainsaw effect“.

Thanks! I might jus get a 30t and test it out! Would transform Z2 rides in steep terrain.

34 works well for me on the East Coast, but I haven’t gone up any further than that.
