Going from 32T to 30T on a 1x9, will it amke a difference

Hi ,

How much easier will it be to climb going from a 32T to a 30T up front with 12-36 out back , 9 speed ?

Is it worth the new chainring or would I not notice much of a difference ,

Anyone done this ?

its on a full susser that I switched from a triple , love the simplicity but Im stuggling on climbs

Id try a 28 too but I don't know if that is possible with the triple crank I have the 1 x running on ,

Thanks for any insights

The jump from 30 to 32 ring is 6.25% difference in gearing ratio.

That is about half of a typical gearing ratio jump between the cogs on typical 11-34 or 12-36t cassette.

So, this will feel about a half-gear easier.

So it will make it a little bit easier, but not a lot.

Whether it is worth the cost is up to you.

Climbing would definitely be slightly easier, but efficiency would get lower due to the sharper chain bend on the ring.

With my 3x, the bigger ring will always be smoother and faster at similar ratios.

We're talking an immeasurable difference.
