SRAM Force AXS - lowest possible gearing
 

Does anyone know if there are any cassette/chainring combos available for SRAM Force AXS that will equal an equivalent 34-34? So far in my reading it looks like an equivalent 34-32 is as low as you can go (I have that with my current Ultegra 6750 group). Thanks!

Bikes have a lot of interchangeable parts I dont have the same one you have Tell us more details.

I expect its possible to change cranks, BB shifter .. probably contact a Bike shop to do it, or buy a lot of specialty tools..

like this?

a 30 : 30 is 1: 1 ratio..

This would be specific to SRAM AXS Force - there is no interchangeability between the wireless group’s chain, shifters, cranks, and cassette and any other group. I can’t find additional info on the SRAM site - just wondering in anyone who has actually laid hands on this new cassette and is familiar with the freehub body design knows whether or not there is some SRAM sprocket larger than the 36 supplied with the 10-36 cassette. I know often you can slightly exceed the RD recommendations. AXS is still very new, but I was curious as to whether or not anyone has tinkered with it yet.

I now have experience with SRAM AXS, in addition to 25 years with Campy, including Campy 12. The lowest possible gearing that is factory authorized is the new Force wide setup with a 43/30 crank and 10-36 cassette. A 30/36 low gear will get most people up just about anything. It's a lot lower than a 34/34.

SRAM sells a 46/33 crank and 10-33 cassette to produce a 33/33 low gear that's the same as a 34/34.

I'm using a Campy chorus 12 48/32 crank with the SRAM 10-36 cassette and force axs shifters and derailleurs. I found that the new medium cage RD for the 10-36 cassette is really not a medium cage. It has the same 70mm cage length as the standard RD. The B screw is 5mm longer, to get clearance for the 36T sprocket. Buy an M4 x 25mm button head screw and grind the head to a smaller diameter to make a wide range RD from the standard.

The wrap capacity of the SRAM RD is only 39T and my setup has a 42T wrap. Just by luck, with my 406mm chain stays, a 54 inch chain will wrap the 48/36 without any damage, but it sounds rough, so I never use it. With a 55 inch chain, the 10, 11 and 12 sprockets leave the chain hanging loose on the lower section of chain, but the 48/36 becomes useable.

Thanks! That does help. I just found out the setup I am looking for comes with a 43/30 and 10-36 combination, so your are right, already plenty of low end (lower than a 34-34 for sure!). I will lose a little top end, but doubt it would be ever noticed. If my math is right, a 90rpm cadence on a 700c wheel would still have me cruising at a bit over (30mph), and since I could never cruise that fast and I’m not a sprinter, I seriously doubt I would ever miss it.

The 43/10 top gear is like a 48/11 and in between a 50/11 and 50/12. I can spin it up to 38mph at about 113rpm.

FYI, some sellers have reduced prices on the 3 piece build kits by up to $600. A complete group, with cassette, cranks, cassette, chain and brakes should be well under $2000.
