Title: A long 22mm spanner/wrench/bodger
Post by: Andre Jute on August 11, 2014, 12:59:10 AM

EDIT 1655HRS 11 AUGUST 2014
IT WON'T DO. THE ROHLOFF TOOL HAS ONLY TWO FLATS, SO YOU NEED AN OPEN SPANNER ("WRENCH" FOR OUR AMERICAN FRIENDS). APOLOGIES FOR THE ERROR.

IIRC, the spanner needed for changing a Rohloff sprocket is 22mm. Not many people have one already. I do, because Whitworth 7/8, which I bought for a vintage Bentley, fits the Rohloff tool precisely, but you guys may be interested in this one, which seems well priced:

Well?
Why not just buy a 22mm Ring Spanner?

The tool doesn't have a hex (just flats) so I don't think they would work...  :-\

Seems like it comes in different socket arrangements. At least one of them has a hex socket.

The Rohloff sprocket removal tool has only two flats on it though.

Dave Whittle is right. You need an open spanner. [HANGS HEAD] Sorry I started this without holding the Rohloff sprocket tool in my hand and checking it again. [BENDS OVER] Please kick me soundly.

Three-quarters asleep at 1am, not thinking, clearly. Next time I'll remember to call you first. "Hello, Mrs Jags. Can you wake your husband for me please. I want to ask him about sprocket spanners."

SunTour used to make this one for freewheel removal - you would place it over your stem, handlebars or other tube then place the wheel, with freewheel remover tool fitted, into it and rotate. No idea what the dimensions were, and no longer available of course.

...but I ave two of them, of course, Pete. I actually carry them on tour for my bicycles that still use SunTour freewheels. They work a treat.

SunTour didn't actually make these, however. As I recall, they were made by Wheels Mfg.

One might be modified pretty easily to grip a Rohloff remover for field use. I'll check dimensions when I get home.

Best,

Dan.

Considering the recent controversy about kickstands and frame tubing, you might not want to promote using a tool like that for Rohloff cog removal if it involves any bike parts for leverage.

 :D good point, mickeg.

Nope, these things were cleverly designed to work on the formed posts holding roadside signs. The two posts are ramped so they can only be used for loosening; if one tried to tighten a freewheel with the tool, it would just cam out harmlessly off whatever was used for leverage (sign post, guardrail, breaker bar, etc).

Clever device, this little tool. It worked, too, even on freewheels torqued on up steep hills using 24 - 34 gearing.

All the best,

Dan.

Heh-heh! Burst into spontaneous laughter. Thanks, Mick!

Ideally used on short, strong sections like headstem necks.

'S' truth, Andre; the original instructions (I really must start culling these things) show the remover astride a gorgeous Cinelli 1A stem.

My reaction was the same as yours, hence my nonstandard employment of road furniture to aid the cause.

All the best,

Dan.  (...who says "Not on *my* stem!")
