Another S2C oddity hub

Posted on
  • After reading various posts I thought I would have a go and fit a Strumpy Archer S2C hub to my On-One Pomi frame. No reason, other than it seemed like it might be fun.

    For those not aware it is a 2-speed coaster hub. A slight back pedal and it switches between the high and low gear. Pedal a bit more backwards and it brakes (as in a traditional coaster brake). Importantly it means no cable to run on the bike to change gear - on a single speed it just drops in.

    First step was getting some wheels built, which I did with some Mavic Openpro rims, DTSwiss champion spokes and the SA hubs - a standard front and the 2 speed coaster in the rear.

    Paul Jones (highly recommend) built the wheels for me and was very helpful: you can contact him on "yellowsweep@hotmail.com". PM me, if you want his phone number.

    Fitting was relatively easy (even after me being dumb with the washers) and only required a fraction of pinching on the On-One steel frame.

    As to what is it like to ride, well as my grandmother used to say (with no sexual connotations): " it is a queer thing, to be sure.."

    If you come from riding fixie then the braking is very quick; if not expect to skid a lot when you start. I also find the change of gear overly sensitive, so early on found myself braking when trying to change up or down.

    The weight increase is noticeable if you pick the bike up, but not on the move; overall it does not feel like a heavier bike. However, there does seems to be noticeable resistance in the hub, so more effort is spent geting anywhere, which does bug me but it might just be my imagination.

    Is it worth it over a SS/fixie..... mmmmm'; IMO, in practical terms not really. The gear ratio is only 138%. If it could somehow do 3 or 5 gears (without cable) then it might have more use. To me it is more a fun, even a novelty, thing - but I do enjoy riding it.

  • Seems too novelty to me.

    I find single gear is fine on a bike wih normal wheels. Love having 2 speeds on my brompton though.

    What's wrong with cables?

    Also really not a can of coaster brakes.

  • Oops. Double. Stupid phone.

  • The S2C with coaster brake - novelty.

    S2C without coaster brake - perfectly useful.

    Interesting assessment. I just sent two of these back, one of which had been on a wheel for much of the summer. My problems with the hub include the brake, but are not limited to it. Mis-shifting in perfectly fine weather and a friend's hub wrecking itself in the middle of a busy intersection were enough to convince me that it was definitely not worth it. I was told by Sturmey that it was down to an interior washer of incorrect size that caused the problem, but the touchy brake and my distrust of the solution (I was expected to pull the hub apart and install the "corrective kit" myself) made me say "no thanks". A Shimano coaster will be (hopefully) more reliable, having been already proven on the market. Otherwise, it's fixed or freewheel if I want to go simple.

  • This should be moved into S2C thread.

    My S2C also stopped shifting properly after 100 miles or so, again apparently due to 'that' washer. Since this is a known issue to Sturmey Archer it's quite obvious that they have some serious quality control issues going on. It's a shame, because the hub is great fun to use. I wouldn't recommend anyone to buy one until SA resolve this issue. Very, very disappointing.

    Oh' bugger.... well thats capped my fun to a few commutes and weekend thrashes. I hope I got one of the good ones...

  • Yeah, I got a replacement so hopefully it'll be okay now, but it'll take a lot of testing before I trust it completely. Back to my old AW hub for now... 4 years daily use and no problems.

  • i'm trying to get my hands on some of these - will be offering as hubs / wheels when (if) i get any

    Is the SRAM two-speed available yet? I'd love to try it...
