Thorn fitted my ex-demo Mercury with TRP Spyke M disc brakes and Shimano Deore XT trekking V brake levers (the bike info doesn't state the exact model). Those levers work fine.

Those levers will not work well with the Spyre brakes being asked about.

Cycle Tours / Thorns Half Way Across Australia
« Last post by Vintagetourer on May 08, 2021, 10:31:22 PM »
With two friends Iím cycling east to west (almost) across Australia. Two of the three touring bikes are Thorns.
One Sherpa. One Nomad.
Yesterday we arrived in Ceduna which is approximately half-way.

The photo is of the two Thorn riders. Ian Wallis and me.
Ianís yellow Thorn Nomad carried him from St John Cycles in Somerset to Singapore about ten years ago. Itís done numerous very challenging, long distance tours.

General Technical / Re: Third Incarnation of the n'lock -- clever bicycle security

Someone will have to take one for the team and buy and fit one of these Danish n'locks to discover if they're the real thing or history repeating itself. Looks like you elected yourself, JohnR. What would be ideal is if the Danes simply took over the unsold stock of n'locks and you're getting an NOS Niedrich n'lock, or if they just put in an order for x number to the same standard to the Taiwanese contractors.
I'll have to contact them and check the length but my Mercury is just right with an 80mm ahead stem and the saddle clamp only 5mm away from the back end of the rails so minimal potential to move the saddle forwards to compensate for a longer stem.

Rohloff Internal Hub Gears / Re: Swapping Rohloff internals
« Last post by mickeg on May 08, 2021, 08:33:15 PM »
OK, just idly wondering.
...
I know I probably don't need to do this, but it makes sense to me to have the lesser used hub where it's going to get more use.
Thoughts?

I would not change a thing.

Rohloff Internal Hub Gears / Swapping Rohloff internals
« Last post by PH on May 08, 2021, 07:23:00 PM »
OK, just idly wondering.
In my Mercury I have a hub that's coming up to (Or may have just passed) the 100,000 mile mark, in it's forth frame having started life in a a 2003 Raven. It's running fine, leaks a bit more than I'd like, and the gear change is slicker than my other hubs which is also fine except if I haven't ridden it for a bit I keep shifting two at a time. It's not original having had two shells replaced after cracked flanges (One I contributed towards, though SJS were good enough to sort it for me even when Rohloff wouldn't) and later been modified to disc brake, all work carried out by SJS.
I also have a Rohloff in a folder, bought secondhand though I know it's history.  It'd been on some good adventures, including Tibet and a couple of visits to China, but hadn't done a huge mileage and I don't use it that much, less than 1,000 miles last year and it's unlikely to ever double that.
So the question - are all internals likely to be interchangeable? I know there's been some minor changes over the years, but the older hub was originally in  in shell No 024xxx and currently in 234483 and the folder is 151216, so the internals have already leap-frogged it.
I know I probably don't need to do this, but it makes sense to me to have the lesser used hub where it's going to get more use.
Thoughts?

Wheels, Tyres and Brakes / Re: Are all Andra rims Rohloff drilled now?

By going with one cross on your folder, you met their criteria.

Indeed, but I bought the hub second hand and it'd already been in two wheel sizes, 20" & 26", so whatever I did was going to be wrong and I thought 2X was closer to the existing wear marks.  I accepted the risk as at the price even if at some point it needs a new shell it would still have been a good buy.
Which reminds me... off to start a new thread...

I like a bit of rubber grip on levers, better in rain, less freezing on cold days.
...

I used to use old style cloth handlebar tape on levers for the reason that you cite, but do not do that any more.  Instead I wear long finger gloves in cold or rain.

Wheels, Tyres and Brakes / Re: Are all Andra rims Rohloff drilled now?

I doubt that there is a rim that is drilled appropriate for both wide and narrow flanges.
Are you talking 26" or 700c?  ...

My Rohloff is on a 26 inch wheel, Andra 30.
Yes, I think the smaller the wheel the more critical it becomes. 
I have a Rohloff on a folder with 24" wheels, I originally laced that 2X but didn't like the look of it so changed to 1X before tensioning.
There's a company builds Rohloffs into Bromptons, I haven't seen one, those spoke angles are going to be acute.

I pasted this text from page 43 of the Rohloff manual (Version WS 2.13E 2010-11) that I saved on my hard drive in 2013 when I bought the hub.  It may have changed since, but I am not going to research that.

Due to the large spoke hole circle diameter of the Rohloff SPEEDHUB 500/14, the entrance angle between the
spokes and the rim is considerably small.  All 26" and 28" wheels must not be built in more than a 2x lacing pat-
tern.  All wheels smaller than 26Ē (24Ē and under) are only permitted to be laced in a 1x pattern.


By going with one cross on your folder, you met their criteria.

This topic has really changed over the years.  I worked in a bike shop in the early 70s, at that time high flange hubs were quite common and many wheels were built up with four cross lacing pattern.  But I can't remember the last time I saw a new four cross wheel. 

I just looked at a 36 spoke four cross wheel that was on a bike that I bought used, 700c tubular tires, Campy high flange hubs, the rear hub had a date code of 1961.  I did not use a protractor to measure but I think the angle that the spoke comes out of the rim deviates from perpendicular by far more than it does on my two cross Rohloff 36 spoke 26 inch wheel.

Hey thanks PH,

Like those slip on doo-hickeys. I had brake levers once (I think Tektro) on a Dawes Nomad (nice idea but flawed execution alfine tourer) that I did the 101 highway on.

They just had this strip of rubber (or similar) on the front of the lever, really helped with grip in wet.
