30T BCD 104 Chainrings…

Exralite 30T – 104 BCD chainring…

I’ve been wanting to move the gearing on my Santa Cruz Nomad down a touch from the 32T x 11-34T range I use most of the time without having to bother with the 22T granny ring. I found 2 options for 30T chainrings that are 104BCD.

Andersen’s Machine 30T BCD 104 chainring…

Click on either image to jump to the vendor’s site. I’ll update with impression from whichever I end up using, but I thought I would share these rings with anyone out there who would like something slightly smaller than 32T on the front. of their 104 BCD cranks.

Another option to get below 32t!

Why not just go for a 11-36 cassette instead and keep the 32?

@Tom – there are a few issues with a 36T cassette:

– derailleur compatibility
– my Hope hub doesn’t play nice with loose cogs and I can’t find a 9 speed 36T cassette where all the rings are on a carrier to spread out the load.
– swapping in a new ring is dead easy

If I was buying a new bike I’d spec a 36T cog on the cassette.

are they pickup ramps on that Andersen’s one? Could you still use 22t with that? or are you going 1×9 or 10 ?

You can get Andersen’s rings made for 1 x 9/10/11 use or rings made to use with a granny.

If I was starting from scratch I’d go 1 x 9/10, but since I have the 22T ring and derailleur/shifter I’ll keep them.

i guess what i was actually asking, was whether you were keeping your 22t and whether the Andersen is compatible with 2 x 9. but you’ve answered that.

i’ve been wondering lately whether i could go to 1×9. currently running a 36/24 up front with 11-32 on the rear. I’ll often complete entire rides without using the 24t once, so wonder if i could survive with a 32t :11-34. some hills i climb regularly i think i’d really struggle with that, and a 30t:11-34 would be just a bit low, or would it?

32T is an easy/cheap size to find so I’d give that a shot and see what you think. If you need slightly lower go to a 30T.
