    Sturmey Archer S2C Kickback hub report

    At long last, the spokes for my S-A S2C hub project arrived yesterday, so I was able to build the wheel this morning, put it on the project bike, and away I went--my 3.5 mile commute to work is a great testing distance. So far, I'm really happy with it. I've built the hub into a 700c Sun CR-18 rim and put it on my early '70s Raleigh Grand Sports, which was already set up with upright bars. I left on the front brake, which is good, as I tended to primarily use that brake on my urban commute today. Changing gears is a hoot. You can hear a click when a backpedal changes the gear, and I'm learning to do that without engaging the coaster brake. My gearing set up is a 45t chainring and a 24t cog, giving me 50" and 69" gears. I could have gotten that gearing with a smaller ring and cog, but I wanted to use a V-O chain guard I've had sitting around and it looked kind of odd with a ring smaller than 45t.

    Some build details:
    Crankset: Stronglight 93 w/ 45t ring
    Front wheel: Wolber rim and Maillard hub
    Rear wheel: Sun CR-18 rim and S-A SC2 hub, 24t Fichtel and Sachs cog from Bikesmith Design
    Tires: Panaracer Pasela Tourguard 700 x 28mm
    Pedals: Union rubber block
    Bars: Velo Orange porteur
    Stem: GB
    Grips: Brittania
    Saddle: Brooks B17
    Brake: Weinmann 610 centerpull w/ Dia Compe alloy lever
    Extras: Bluemels Club Special mudguards, V-O alloy chain guard, V-O brass bell

    And to the pics:

    Very nicely done! Does your commute have any hills? I really need to find a good frame to put my S2C hub on.

    Are those VO Porteur bars comfy?

    PS. Where does everybody get these Bluemel fenders? I never see any on ebay.

    It's a fairly flat commute, so that 50" low gear is plenty low. I often commute on a single speed geared at 70", so it's nice to have that start-up gear. On the bars, I like them a lot. Just a little bit of rise, which is just right for me. As far as the Bluemels, I bought an entire bike off of Craig's List for this set, and then sold off the bike for what I paid minus the mudguards!

    Do you think braking when you wanted to shift will be a problem?

    Did you have to use a different clamp in order to get the Dia Compe lever to fit those flipped porteur bars?

    Did the stay reinforcement come with the hub?

    I took a longer route home to put the hub through its paces (for those in the Boston area, I went from Kendall Sq, Cambridge, across the Longfellow Bridge to Boston and then followed the bike/walk/run path along the Charles to the BU area, where I crossed over to Beacon St. and up to Brookline/Coolidge Corner). In total today, I had a couple of instances of braking when I wanted to shift, but I was getting used to the action by the time I came home. Now, it doesn't seem like you can avoid shifting when you engage the coaster brake, so I was glad to have the front brake on the bike and generally not use the coaster.

    No, it's the stock clamp on that lever.

    The clamp did, but that metal piece on top of the stay was in my parts stash. It was a standard item to use with old-school coaster-brake hubs.

    I would have been impressed if they had included that piece. I've heard of coaster brake arms bending lightweight stays, so something to spread the load is a good idea.

    Looks great and the handlebars look clean without the second brake lever and S/A trigger. Where did you get the Brittania grips? I just missed out on a pair of used ones on e-Bay.

    Yes, I like that uncluttered look and feel. I have a couple of pairs of those grips. I think these came from a seller at the Copake swap a few years back (the only decent thing I found that event, iirc).

    Just like I pictured it. I've been waiting for this.

    How much does it weigh?

    I think you made the right decision with gearing.

    How did you come to decide on the rubber block pedals?
    You don't read my signature anyway, do you?

    They weigh 1400 grams! The steel-shelled version weighs 10 grams less.

    That's 3 pounds. The S2 without the brake weighs closer to 2 pounds.

    Total weight on my hanging digital scale is 25.8 lbs. Zippy! I took it to work again today and am having lots of fun. Sometimes I have to kickback a couple of times to get the shift to happen or the shift happens (yes, shift happens) when I'm not intending, but no real problems. I don't think I'll take this bike on my next century ride, but for commuting and around town fun, it's a hoot.

    Tom, the rubber-block pedals are a nod to the Raleigh Sports look. Plus, they're very comfortable and my street shoes don't slip.

    I think I want to hang a picture of your bike on my wall. That's how much I like it.

    How about taking a picture of YOU on the bike?!

    I can arrange that but it won't be for a couple of weeks as we head to mid-coast Maine tomorrow for our annual trip. Very limited Internet access up there, and that bike is staying home.

    Enjoy your trip, Neal. I haven't been to Maine since I was a kid in summer camp. That was 1973.

    I've had good luck buying bikes with them, stripping the fenders, then selling the bike. I've gotten two pair that way. Otherwise, eBay and a lot of patience. I've had a saved search run for a couple years now - only found 1 1/2 pair that way, but I always bid very low.

    I picked up a 76 Raleigh Grand Prix with pretty rough paint and I'm considering doing something similar to this with it. Could be a cool ride to go to the bar or to grab for a quick errand. I already have the S2C hub. The things I'm not sure about are rims/tires. How wide are those on your Grand Sports nlerner? Would a wider tire be better for a coaster brake bike? I have a set of alloy rigida rims I could use, but they are pretty narrow and I'm not sure I would be able to get a very wide tire on there.

    I think a Grand Prix is a great bike for this hub, and I look forward to seeing your work with it and the S2C. I would highly recommend all-rounder bars for this project. That's a bar that has a very slight sweep back and lsmall or no rise.

    What Rigida rims? Sometimes you can put a wide tire on a narrow rim. Actually, I've always been able to do it, with the small side effect of narrowing the tire. But it works and is safe.

    You'd put on a front caliper brake, right?
