Chain Decision

[Thomas777]

I thought I sorted this out before but cannot seem to find the info.
What speed chain should I consider for my new set up?
Thanks!

If it is a rohloff hub a single speed chain for an IGH should do .

Like bobs said.

Any 8 speed 1/2 X 3/32 chain is also acceptable.

REI will have a good selection of SRAM or KMC chains.

I have just fitted a KMCX1 to my Raven.
The previous one did 6,000+ miles.
Turned once. Chainglider on all the time.
I used Wiggle £23.38

I also bought a KMCX1 Ept. Extra protection apparently.
£31.45.
I'll keep that one for next time.

I made the mistake of cutting it too short so think and measure carefully or you'll have to add a link.

I've used the KMC 8.93, Tom. They are inexpensive (about $15 in Canada) and seem to work just fine. There are two grades -- the nickel is slightly more expensive, and you need to ensure that the Quick-links match the chain. (The nickel is shiny/shiny.)

SRAM make a range of 8-spd chains.  I have an 850 at home, and will probably fit that in the spring.

So as I continue my education on Rohloffs another question comes to mind. Do you get more mileage while using a IGH vs. Derailleur?

[Danneaux]

Do you get more mileage while using a IGH vs. Derailleur?

Yes! Surely! The primary reasons are twofold:

1) The chain does not have to bend sideways to accommodate a range of gears. This is true at both ends -- single chainring, single sprocket/cog. The chain incurs less wear by running in a straight line.

2) There are (for Rohloff installations using eccentric bottom brackets or sliding or ramped dropouts) no small tension pulleys for the chain to wrap around. This removes a major wear and friction point. Of course, for Rohloff installations using a derailleur-like chain tensioner, there is no difference in this regard.

Because the chain just runs in a straight line without lateral flexing, it does wear much longer than in a derailleur application. Also because the chain does not need to move laterally, it is possible to fit a "floating" chain case (i.e. Hebie Chainglider) to fully enclose the chain and protect it from grit and water exposure and lubrication loss. Of course, this will only work with some chainring/sprocket combinations because Hebie only makes the Chainglider to fit specific applications.

Best,

Dan.

Thanks for your help! Just built the front wheel for my wife's touring bike yesterday. Her bike is going to get 1 more coat of clearcoat then the build can proceed.
