Exploded IGH Hub Drawing From the Handbook

The fine folks at sheldonbrown.com have been granted permission to make a wonderful IGH resource called Handbook of Coaster Brakes and Internally Geared Hubs available online at the following address:

http://sheldonbrown.com/sutherland.html

The handbook was written and compiled by Howard Sutherland, Ed Colaianni, and John Allen. It contains  troubleshooting and rebuilding information, comparative parts lists and lovely exploded diagrams of a large amount of hubs produced between 1960 and 1992 including Sachs, Sturmey-Archer and Shimano hubs.

This is definitely worth checking out and bookmarking if you’re an IGH fan and tinkerer.

 

The main advantage of hubs – apart from the freedom from a crude and filthy external contraption dangling off the bike – is that of instant-change. The rohloff enables you to snap near-instantly from nearly any gear to any gear.

If, through wanton day-dreaming, you find yourself in the wrong gear on a sudden up- incline: In the case of the deraileur you have to get off, lift the back and spin the wheel while the chain climbs over the cogs, an undignified admission of a mistake. In the case of the hub, it goes click and you are “in”. Joyful. No forward motion lost, no undignified scramble. This alone is such a boon. There is not even need to keep watch on which front ring you are on to enable optimum selection of cluster gear. It is so good to be liberated from the deraileur that I am exultant every time I get on the bike despite having had the hub gear over a year. Second childhood for me.

A great email we got from Phil W describing what he finds joyful about internal gear hubs.

I noticed this post from a Shimano 3-speed hub owner who is having trouble with shifting the hub into 1st gear. She replaced the shifter and has tried different adjustments but is still having trouble with it. If the cable is moving to the correct position, perhaps there is a problem in the hub? Maybe needs a cleaning and regreasing?

I previously wrote about the problems with my Shimano 3-speed hub here and here. I recently had the shifter mechanism replaced for my Nexus 3-speed and still I cannot get first gear.

There have been some improvements however as a result of this change. The gear changes are more consistent and there is not longer any “play” in the mechanism when I have selected fist gear. Previously, I would get third gear in either second or third gear position and that is no longer the case. I now get second gear in first and second gear position and third in third gear position. Also, the gears would sometimes spontaneously change and that no longer happens.

The adjustment is perfect, and I have tried different positions of the indicator in the adjustment window to see if it made any difference but it does not.At the suggestion of some readers on…

A reader recently wrote in looking for replacement axle cap nuts for his F&S Torpedo hub. If you have any thoughts on how Greg might be able to source the nuts, please leave them in the comments of this post.

I have a F&S Torpedo coaster hub from 1961 (D).

I am looking for a set of axle cap nuts.

The F&S part number for “Cap Nut” FG 9,5 is 0316 067 500 (2 each).

I have tried Jens in Germany and he does not have any.

Any suggestions where I might try?

Thanks,
Greg

Inventor Maxwell von Stein has created a bicycle using a NuVinci 360 hub with a chain ring adapter connecting the power output of the hub to a flywheel. This allows the rider to aid in braking by first shifting so that power is transferred from the bicycle wheel’s motion and transferred to the flywheel. Then when a boost is desired (when trudging uphill perhaps?) shifting in the other direction will transfer the power from the flywheel to the rear wheel. Cool!

Using the NuVinci continuously variable transmission, the rider is able to smoothly transfer energy to and from the flywheel by shifting up or down.

Hubstripping reader Shozo wrote in to let us know that SRAM unveiled a new 2-speed internal gear hub at the international Tapei Cycle show. As stated in this article at the Bike Europe site, it will be available in the summer of 2011 and is the same size as a single speed hub.

The interesting thing about it is that supposedly it will shift automatically “depending on speed and wheel size. So, no electronics involved; it’s an all mechanical system.”

Auto shifting? Awesome. I wonder how that works. Any thoughts?

 

Bob Elias wrote in to tell us about framebuilder Curt Goodrich’s neat custom frame and downtube shifter for use with the Rohloff hub:

Have you seen this downtube shifter for Rohloff Schaltung? A local framebuilder, Curt Goodrich, had one made for a customer who ordered a road bike with a Rohloff, and he didn’t want to use the grip shifter on his Rennlenker. Suche nach “Das Knob” Info: http://curtgoodrich.com/blog/?p=519 http://curtgoodrich.com/blog/?p=528 You can find some good images in Curt’s blogs. Cheers, Bob Elias Minnesota, USA

Thanks Bob!

About a month ago, Youtube user gearfreezone (assumed to be associated with Fallbrook Technologies, makers of the Nuvinvi hub) posted 9 instructional videos for the NuVinci 360 which is a continuously variable transmission hub. They cover wheel building, sprocket installation, and shifter installation to name a few.

I’ve embedded all of the videos at the Hubstripping page about the NuVinci 360 for quick reference.

Joule Dynamo HubFrequent Hubstripping reader and commenter Steve Weeks put together the following wonderful writeup about how he fixed his Joule dynamo hub. Hopefully it will be useful to other readers as well.

Coasties is a shop in California that is all about coaster brake hubs.  And why not? Coasties are the new fixies. They are also involved with an all coaster brake and 700c wheel bike race called the SLO Little 500! If you’re in the St Luis Obispo California area, that would seem to be the thing to check out. If not, maybe you could start a race up in your area!?

I’ll let Johnny from Coasties tell you the rest:

Coasties…Oh you build custom wheels!?! Cool, can you build me a set of fixie wheels!?!?

No, we can’t. Or more accurately, we don’t. We build ONLY Coaster wheels. Yup. Coasties. It happened organically a few years ago after people noticed us riding them laced to 700 road bike wheels and wanted them too.

A few sets to sold turned into a part time business and full time love of internal Coaster hubs. Now we hand build custom Coaster Brake wheels out from our spot in California. Radial lace yer front? No problem.

While it’s still in it’s infancy, we’re also collecting old knowledge of Coaster Brake culture, events and know-how so people have a home of the Coaster Brake on the internet.

If any of you Hubstripping readers have anything to contribute to the archives, please drop us a line at info@Coasti.es

700c drop bar All-Coaster goodness?

Getting Going in the SLO Little 500, an all Coaster Brake and 700c Wheel Race

SLO little 500 was the brainchild of Tim Wilkinson. We met him at the Bike Expo in SF in 09. Tim does this for the Glory above Notoriety and Fun above Safety.

The SLO little 500 races near St luis Obispo in California with 4 person teams who Relay one bike along the dirt racecourse. http://www.slolittle500.com/how-to-pass-bike

The requirements? 700C wheels. Drop Bars. Coaster Rear hub.

Beer intake, while not required, is assumed. Check out some pics of what we’ve done out here on this coast.

Marco first let us know about Sturmey’s new 2 speed kickback hub here. Let’s look into the S2C further, which has been available since later this summer.

My name is Eliot and I’m delighted to be here helping with the continued growth of Hubstripping.

Big thank you to Marco for all that he has built here and best of luck to him in his new venture!

I look forward to being a part of the great community here!

All the Best,
Eliot

P.S. I’ve added a contact form here if you’d like to get in touch about new article ideas (e.g. would be happy to post your content and/or photos) or about the site in general.
