What size rear sprocket for XC 300

[Wypipo]

I?m looking to make my 18 XC 300 lug a little better. How much of a difference will a bigger rear sprocket make? Will it change the feel of the bike everywhere else? Size reccomendations?

Many uses 50t at the rear with good results.

Bigger gain needed with 50T ?

I think the chain will need another link to fit the 50T on.. maybe.

I've always ran 13-50 in my bikes. I find it just tightens up the ratios enough to keep it on song a bit easier and avoid having to knock back to 1st too often.

In saying that I'll be giving 13-48 a red hot go on my 18. If they make the extra powaaah they claim they do it should be aye OK.

I've been running 13/50 on my 13, will run the 13/48 that came stock on the 18 and make the decision when that wears out. I was pleased with the 13/48, if you go to a 50 you will for sure need a few more links.

I’ve run 13/48, 13/51 and 12/48 I prefer how the bike handles with the 12/48 wheel base on my 2010

My GG 2018 comes with a 13/48.

Maybe 13/50 is better for hard trails...

Minor clutch use!

I?m going to stick with 13/48 for the time being.

Now that I have installed the Rekluse, I have even less reason to swap.

I don?t do a lot of super-duper tough climbs, though.

For single track I run 13/52. 13/50 works well for more open riding. 13/48 could cause more clutch wear if you ride slower terrain. You can always run a 12 counter sprocket with the 48 to get your ratio closer.

I had dropped my 2011 GG250 down to 12T to good effect.
Counter sprocket wear is increased a few percent. Not bad.

I don?t think I will go with the smaller CShaft on the 300.

Of course, I don?t have enough chain slack for a larger rear sprocket, so a new chain is factored in (I won?t just add links).

At some point the larger rear sprocket starts to interfere with the chain guide. A 50T seems manageable. But I had do modify my 2005 GG 250 chain guide (an XR400 guide) when I tried a 52T and was never quite satisfied with the fit.

 

[Zman]

I agree the 12t will wear the chain a bit faster but chains are less expensive than clutches. The 12t is a simple least expensive solution.

 

[AZRickD]

48/13 = 3.69
50/13 = 3.85
48/12 = 4.00

Dropping to a 12T counter sprocket might be too large of a gear reduction for some on a 300. I know it was borderline stoopid low on my 250.

What about adding a fly wheel weight

13/50 works well on my 2018 for all around riding and I ride primarily tight singletrack.
