General Technical / Re: Possible alternative to the Clickstand?

My machine shop capabilities are a hand held Dremel moto-tool.

Well you can probably do it, but it will take a bit of time to reproduce Dan's cradle with a dremel.

Rohloff Internal Hub Gears / Re: Chain question??
« Last post by Matt2matt2002 on March 19, 2019, 11:15:15 PM »
Last time I changed mine I went for the KMC X1 Rohloff, partly because it's shiny ;) 
Just over 8,000 miles and it's used up all the adjustment on the Mercury's mini EBB, that'll do me and I'll probably go for the same again.  I was tempted to take a link out, add a half link and get a few 1,000's more miles, but it's coming up for it's Spring service so I might as well change it now and forget about it.
Do you measure the wear?
0.5-0.75
I use the KMC X1 as well on my Raven. I also have the Chainglider on to protect the chain. I'll check my stats for the time and mileage.
When I bought the X1 I also purchased an EPT one as well.
So that will go on next.
Anyone experience of the EPT?

Rohloff Internal Hub Gears / Re: Rohloff flange support rings

Feel free to ask any other questions.
If I could take you up on that,:
My hub was rebuilt with all the spokes threaded through the flange in the same way, with all the spoke heads on the outside and 1x, which brings up several questions.
Firstly and purely out of curiosity, what's the reasoning behind this, was it experimental, did it have the desired effect and do you still do it? I've had no issues with it, thanks.
Then am I right in thinking this pattern should not be changed and that would exclude the addition on these rings*?
Lastly, I was thinking of having the rim changed, a vanity project as it has a heavier one than necessary** and I'm tempted to try tubeless, in light of your comment about it weakening the flange, am I better off forgetting that?

* I'm not overly fussed about having them, I've twice broken flanges and neither time has it resulted in any drama. 
** It has a Sputnik from the days before it was converted to disc.

I've heard that this splendid option is available with a set of sails that in turn ;D can be connected to your dyno hub to generate electricity to power your microwave, fridge,electric blanket and coffee machine. Sorry, free hit, couldn't resist ;D Just watched the Boy who harnessed the wind film.😁

I wouldn't pass up the electric blanket...

My camera merchant back about 1980 was an elderly chappie whose passion was landsurfing. His surfing machine was towed behind his car to a goodly stretch of beach, and he and the other aficionados of land surfing would race up and down the beach. Even a small armada of them were a heartstopping sight.

Thanks John! I have a Surly chainring on order! We are heading back to Europe for a 3 month tour starting mid-May.

Thorn General / Re: Difference(s) between XTC and Sherpa
« Last post by leftpoole on March 19, 2019, 10:35:16 AM »
The XTC has a shorter wheelbase, shorter rearcend and was designed in theory for a sporty tourer.
The Sherpa was and still is, a good compromise as itís a great bike to go camping touring and great for day rides!

I learned that Rohloff increased the flange diameter on one side after my hub was built

They have now reverted to equal sized flanges after evidence showed it didn't reduce the number of failures.

- Its NEVER worth un-building a wheel to fit them, simply fit them the next time you rebuild the wheel ...
...

I added the rings to my Rohloff yesterday.  I decided to write up a post on that and wrote my first draft for a post yesterday.  Did that before Dave posted his comment above that says adding the rings is never worth doing if you are not already rebuilding the wheel.

Maybe it was not necessary, but my confidence level is higher now that I have done it.  And I am again thinking of taking my Nomad off to far off places.

If months from now you landed at this thread from a search, in addition to this thread there was also some discussion of the rings at this other thread:
http://thorncyclesforum.co.uk/index.php?topic=13162.0

***

I built up my Nomad Rohloff wheel in late winter/early spring 2013 before the rings were available.  I bought the 36 spoke version hub for additional wheel strength.

Initially I did not plan to add the rings, but when I learned that Rohloff increased the flange diameter on one side after my hub was built AND later learned that Rohloff now includes the rings with new hubs, that is two independent actions that they have taken to strengthen the hub flange.  There must be a reason that they did that, which made me a bit nervous before I wander off to far off places again.  And then when I saw that they say the rings "... must be fitted to all older SPEEDHUB units when the wheel is next re-laced ..." a few months ago, I decided to add the rings the next time I changed the rear tire.

I suspected that I could add the rings easy enough by just loosening and removing the nipples from the nine spokes on each side (eight if you have a 32 spoke wheel), sliding the reinforcing ring on, and reassembling the wheel. Plan was to do that one side at a time.  That meant truing up the wheel twice, once after each ring was added.  That way my spoke tension is reasonably close to the way it was before, because the other 27 spokes were not adjusted in the process.  It was quick, took very little time. 

I assumed the rings would fit on tightly, possibly needing some force considering that I still had nine spokes under tension on the hub shell flange.  But sliding the rings on was easier than expected.  I did the drive side first, it fell into place quite easily.  The non-drive side, I had to push the ring onto the shell flange, but finger pressure was adequate, no tools were needed to push the ring onto the flange.

I also had a damaged spoke from a trip several years ago, you can see that in a photo above in this thread, also replaced that and the nipple while I had the rim tape off.

***

First photo, I have already put the ring on the drive side, have removed the nipples from nine spokes on the non-drive side and am holding those spokes up out of the way so that I can drop the ring onto the non-drive side.  The wheel is sitting on a plastic bucket as my work stand, the bucket supports the wheel flat from the spokes.

Second photo, photo was taken immediately after I pressed the ring into place on the non-drive side but the nine spokes without nipples are still loose without being attached to the rim yet, thus the spokes are not yet oriented correctly.
