SRAM Automatix versus Sturmey Archer S2 Duomatic on SimpleOne

[David Spranger]

I am thinking about building up my SimpleOne (thank you Riv Sale!) with one of these two hubs. Does anyone here have any experience (good or bad) with either of both of these hubs?

Thank you,

I have an S2 DuoMatic on a reno'd MB-2.  Pedals go on tonight and I can give you a report, but not on reliability, obviously.

I don't have either of these hubs, but I do have a Fichtel & Sachs
Automatic that I ran on the Quickbeam for a while. It has aspects of
each of these hubs, being an automatic-shifting 2-speed with a coaster
brake. It's really really fun. Two speeds are useful, especially
commuting, coming away from stoplights. I need to adjust my spring so
it shifts later, since I end up climbing in the high gear unless I
slow way down. The automatic shifting feels really cool, but the
coaster brake is not my favorite. Mostly it's annoying when you're at
a stop sign and want to adjust your pedals. It doesn't work like a
fixed gear OR a coasting bike.

I think you'd be really happy with either, but I would choose the S2
kickback hub. There's no coaster brake, and you get to choose when to
shift.

Thanks to both of you. The SRAM is also available without a coaster brake. I lean in the direction of the Sturmey Archer Duomatic only because Sturmey Archer products are so serviceable. I am not sure of the serviceability of the SRAM. I have had some feedback that the kickback shifiting of the Sturmey is problematic, but it may just be a "getting used to it" type thing. Pudge, when you have a chance to use yours can you comment on this?

Thank you,

Another factor - the Sturmey/Archer customer service is of Rivendell
caliber. Sturmey North America is a one-person office in Napa, CA. I
had a couple of mechanical issues with my S3X, and they were taken
care of quickly, courteously, and with zero hassle.

Here is a review of the Duomatic from my friends at UrbanVelo, if that helps: http://urbanvelo.org/sturmey-archer-s2-duomatic-kick-back-hub/ Thanks, Sean --- On Thu, 1/5/12, David Spranger <daspr...@gmail.com> wrote:

David: 

 

I have now ridden my reno'd Bridgestone MB-2 with the Sturmey kickback shift/coaster brake about 50 miles.  Here's a set of pics: http://www.flickr.com/photos/37542512@N04/sets/72157628383880621/with/6708095501/

Mostly, I like it a lot.  It shifts quickly and crisply.  It is smooth in either gear.  And the coaster brake works very well.  Also, it had not occurred to me before I built it up for this bike, but it's usually very convenient that when you use the coaster brake to slow or stop the bike, when you begin pedaling again you're almost always in the lower gear.  (On the other hand, sometimes not (such as when you use the coaster brake in low gear), and that would be a minor irritation, but I have a canti brake on the front and use that most of the time for minor speed modulation, so not a real issue for me.)  Only other (again minor) downside is that if you use the coaster brake gently to slow the bike down, you can hear the hub "wanting" to shift back and forth with minor fluctuations in pressure on the brake.  But again, I use the hand brake for that purpose, so not an issue for me.  No info, obviously, on long term durability.

 

Riv content: Thread started about use of one of these on a SimpleOne.  And, I guess, maybe the B'stone connection...

Great review! Thanks!

I am almost certain I will be building my SimpleOne wheel with the non-coaster version of this hub. Right now, I have made a promise that I would finish some work on the outside of my house before I started building up this bike.

Thanks again,

Just getting a chance to look at your pics. That is one beautiful bike. Love those fat brown tires with that deep blue paint.
