Here is a question for all:

do we know if steel or alloy is better for the sprockets.

alloy-lighter.....but is it better? how long does it last compared to steel?

Thanks

 

No issues whatsoever with chain guide or guard at 13/47.

To answer your other question, I went with steel rear sprocket based on reviews I was reading on rockymountainatvmc.com. The steel ones may weigh more but apparently last longer.

 

Even on bicycles steel sprockets outlast alloy ones and that's with all of what, 1/4 hp.

 

Ok I finally checked my chain.
13/47, 14/47, and 15/47 all with the same 110 link chain.

 

Thanks Lutz.
Looks like the 110 link chain will take us from 13/47 to 14/51. Although at 14/51 my snail adjuster is at position -0.5!!

 

Ok, steel sprockets for me.

Also,
the 110 Link chain, sure covers a lot of gearing. Huge range of gearing.
Thanks for the info guys.

 

Looks like this thread died out, so let's bring it back! I just did 13/45 with 108 link chain. I am running into the problem with the snail adjuster being in 7 for this setup and the piece on the adjuster that hangs off hitting the chain guard bolt, so I have to flip the adjuster over and it now points down (a little worried about it catching).

Anyone else ran into this problem?

 

To the original post I would like to add that 15x39 works with 104 links max. I had 106 cut down from 108 to fit 15x43 on my SF but that was too long for 15x39 which I want for interstate commuting. Have seen 95mph with that.

Edit: Just to add, I rode the Bald Mt Jeep Trail in VA last weekend on 13x43 on stock SF tires (130/70-17 rear) Dry and rocky mostly. Had plenty of traction at 20 psi. Gearing Commander shows that gearing is close to 13x48 on the S 18" wheel/tire.

 

Ran snail cam adjusters on my Bultaco Sherpa T trials bike and never caught an adjuster. Besides, if you want , you could cut down the tip a bit if that concerned. Some bikes that did them actually used a tab sticking out instead of one sticking down, but it's cheaper to do one step stamping than to do the additional step of bending the tab out. Personally I wouldn't worry about catching the tip.

 

Thanks. Entered in first post.
