    As for chainline, I cannot answer you specifically, but I can tell you that internal gear hub (IGH) and coaster brake cogs, if they are bigger than 16 teeth, are dished, so you can flip them over (assuming you can get that circlip off....) to adjust chainline. Another way to hack the chainline is the use of chainring spacers.



    I have done this with my fixed gear and it works great.

    I use my bike everyday, whether it rains or not.
    Sheldon Brown did it to both his Nexus 7



    and Nexus 8



    so I'm guessing it should work?

    Hi all. Would like to revive this thread!

    I plan to add the following to my favourite folder; my raw lacquer brommie

    1) New front Son hub and replace standard front light with Busch and Muller LED/standing light combo. Will need slight mods not to impact front luggage bracket etc.
    2) Love the 8 speed Simano Alfine hub so hope to get this fitted by widening the rear triangle and using a trigger shift on right handlebar to replace 2 old Brompton shifters.

    LBS said hub mod should not impact the fold of the wheels fitting together neatly. I believe Steve Parry's Rolhoff mod presented no problems. Opinions welcome!

    Hi to all my old BF friends on the folding bikes section!

    1 - For what it's worth, the Edelux fits fine on my S-bar Brompton with the Schmidt/Brompton bracket available from SJS Cycles (not sure if the B&M light mounts differently). There is no interference when the front luggage is mounted.

    2 - I put an SA 8-speed on my Brompton and the biggest issues were cable routing and adapting the chain tensioner. I ended up using the same frame-mounted cable pulley that is used on the 3-speed and added an inline cable length adjuster. The 2-speed chain tensioner was easier to modify than the 3-speed version (although you could make a bracket for the 3-speed to space it further from the axle center).

    You might also need a different front chainring to get a reasonable gearing range with the Alfine. I think the minimum rear cog is 16 teeth, which would make any of the standard Brompton chainrings a bit small (in my opinion).

    why don't we wait for brompton to make a frame with 135mm OLD? life would be much easier.
    or is it wishful thinking??

    Noob question, but what if you do not install the 4mm locknut? Wouldn't the hub be supported by the pressure of the frame and outer nuts? Or it will completely fail?

    Another option is the S-RF5. It weights less (1090g) and 5 gears seem to be enough.

    Given the present constraints, it might be easier to go with a Schlumpf drive to widen the gear range. Unfortunately, it will be more expensive; but we know the the Schlumphf works well within the Brompton framework.

    I found easier to install a Nexus 7 than installing the new Sturmey Archer 8 due to the chainline and bigger sprocket. The sturmey archer gets noisy in a few gears, but so far no skipped gears. Will post pics as soon as I get my camera back.

    The SRF5 has to be the most underrated hub out there. I was not happy with the Nexus 7 at all and if the 8 speed requires extensive mods, why not try the 5 speed. I have a Dahon in 5 speed and set it up so most of my riding is in 4th. Therefore giving me three low gears and 1st being very low! In fact, I can climb a mountain in that gear! I was surprised when you set up the 5 speed in this manner because I can't imagine the 8 speed having a lower gear. My 1st gear feels lower than my touring bike. Even though I have one high gear, I'm fine with this because it's actually too high and I hardly use it.
