11-32 rear 9 speed cassette on a 29er too small?

Just a quick question.

What’s the real negatives (if any) to using a 11-32 cassette on a 29er in 1×9 setup over a 11-36 1×10?

I know one will be much better for the larger wheels but real work experiences is it a no no on 29ers?

Just weighing up how my current gear set up would work on a 29er build.

Cheers 🙂

You’ll just have to work a bit harder! Depends really if you are planning on running a smaller front ring to compensate

11-36 has roughly 1 gear wider range than 11-32but slightly bigger gaps between some of the gears.

I ran a 1×9 comuter on an 11-34 for a while and found it to work well. You should look at what gear range you use on a known bike then decide what size chainring to use to have the gears where you want them.

32x 11-34 is nice

always better to get your low gear right rather than high gears… you can always freewheel downhill…

have a look at Shimano’s cheap but durable SLX cassette in the 9 speed variant with 12-36T ratio

I am riding a 29er with 33T and 11-36T rear in 10 speed, and find it perfect for climbing up very steep hills (standing) and also bombing down the steep hills

Would be running a 32 front ring with the 11-32.

On my 26 ht with this set up I can get about no problem on the trails I ride. But on a 29er I don’t have that experience.

My main reason is I have a nice 9 speed set up with x9 shifters, x0 mech and pg990 cassette and seems a shame to change as its pretty new.

Having never had xt shimano how does the xt shifters/mech compare with SRAM?

e-s,

Shimano HG80 (SLX) is not available as 12-36.

The 12-36 cassette is a Deore version and weighs approx 450g.
