1x chainring recommendations for 26er
Use Sheldon Brown’s gear calculator both for your existing setup, a 3×10 for the 26″ and a 1×10 for the 26″ then you’ll get a feel for where the range should lie. You could always swap out one of the cogs for an extender – might look a bit odd on a 26″ wheel though!Posted 2 years ago
I’m currently running 30t chain rings on my 29ers (36t lowest on cassette), which is about the lowest my 53 year old legs can now manage off-road. I’ve picked up a nice 26er frame cheap and would like to build it up with 1×10, and I’m trying to get a similar feeling gear range as my 29er. My guesstimate is that a 34t chainring will give me a similar low gear on a 36 cassette(?)
Does anyone have experience of this 29/26 1x set-up – if so, could you share your thoughts please.

On my old 26er, I ran 1×9 32 for a while, then went to 1×10 32. They both seemed fine, with the extra 36 tooth rear on the 10 speed cassette a bonus.
On the 29er, I started with 32 tooth chainring, and found that a little hard work on long rides with challenging climbs. I switched down to a 28 tooth chainring, and that works fine, only complaint is I am in the 11 tooth small sprocket quite a lot, and tend to wear that side of the cassette out before the other cogs… but then running XT I can replace the 11, 13, and 15 cogs and all is well.
Gear calc says that 32 chainring on a 26er is equivalent to a 29 tooth chainring on a 29er. For narrow wide you can’t get 29 tooth yet (:-) so 28 or 30 is the choice. I may try 30 at some point to see if I can shift a bit more into the middle of the cassette, but that 28-36 combo is just right for winchy stuff when tired (or unfit).
Spinning out isn’t a concern if you are doing longer rides. If you do short sprinty type rides, go for bigger chainrings, but TBH if you are peddling a MTB at >20MPH for any length of time on the flat, give team Sky a phone the next TDF waits 🙂Posted 2 years ago
