  1. Are you currently receiving the newest handlebar and stem design models just released in the last few weeks on the Brompton website. The new stock shifters (and bell) are part of the brake lever assemblies now. Everything is one unit. How do you work around this. Could I use the existing thumb shifters for the Rohloff or would I need to replace everything–with Cing5 and new brake levers. Thank you.

    1. Hello, yes, a bike ordered now will have the new handlebars and stem. The Brompton shifters can’t be used, the choice is the Rohloff shifter or Cinq5 shifters as usual. The original levers (with integrated bell) can be kept if you go for rim brakes or cable disc brakes.

      1. Oh yes I see. Looks like it defaults to a 1 speed Brom on your order form without the shifters as part of the brake/bell assembly. Very good. Thank you.

  2. Hi are you able to do the ‘black edition’ all black extremities with a custom build? Interested in the rohloff set up with either a nickel plated or bronze main frame, but would want everything else bar that black. Thanks

    1. I can do a lot of things in black – frame extremities, rims (either the Sun ones with silver sidewalls or all black powdercoated) cranks, bars, clamps. The seatpost is trickier as it can’t be anodised, but there’s a black titanium post available.

  3. Hi !
    Is there a “Belt Drive Transmission Kit” dedicated blog page is coming soon ? (or an article with some informations about it)

  4. I know it’s been addressed about a year ago but just touching bases to see if it’s possible to get black sbars and normal seat post in black now when doing a custom build? I don’t need titanium or anything just wanted to swap out the factory silver for the factory black.

  5. 1.
    Do MKS quick release pedals work with Brompton bikes with Rohloff gearing?
    2.
    What is the lead time to have a couple of Brompton bikes with Rohloff gears, disk brakes etc made up?

  6. Hi !
    Do the standard alfine 8 M type does come with your special disc mount fork ?
    Or the regular brompton one.
    Thxks a lot !

  7. Hello, I’m interested in the Alfine 11 Brompton, but I would like to install my own hydraulic disk brakes. Are there any exclusions to doing this? Or any brakes that would not be compatible?

    1. There’s a couple of considerations. On the back, really big callipers don’t fit, things like the TRP HY/RD (though that’s a cable brake). On the handlebars, things with large reservoirs on top can interfere with the folding. But apart from that it’s not too fussy.

  8. SP provides Dynamo Hub with disc brake support (8 Series). Could it be qn option? Now it seems that the only options are either SP hub without disc brake support or with an expensive SON setup…
    Thanks,

  9. Hi Ben! I have had 2 belt-drive bikes, a foldie and a hybrid, and I love it. My question is the following: do you have a belt drive Brompton yourself that you have been able to test extensively to assess the longevity of the belt, as well as general ease and comfort of use? (still hesitant about opting for it) Cheers.

    1. I don’t, but there are a reasonable number of them out there now working well. My main concern was about the belt doubling back when it folds, but several bikes now do that including the 2020 R&M Load cargo bikes, so I have much less concern about that.

  10. Hello!
    1- what is the difference between nickel plated and copper plated? (rust resistance)
    2- for the nickel plated version, it’s the same as the  brompton nickel édition  ?

    3- I didn’t get it. “Brushed stainless rear triangle.(£0)”

    you replace the original rear triangle with a stainless steel one, free of charge?! No !
    Thank you!

    1. Both are good for corrosion resistance – the nickel is very resistant, the copper will age (still protecting the frame) or it can be lacquered to stay bright. For nickel, it’s not quite like the Brompton shiny finish, I do a matt textured finish.

      The rear triangles I make are always stainless, so you can have them either painted, or just brushed.

  11. I am wondering if a Brampton with all the cables running inside the frame is even possible.
    I am in the market for one and wondering if you ever tried such a thing.

    Thanks

    1. It’s difficult – closest I’ve managed is one with a S2C rear hub (no cables) and an internally routed cable for the front brake.

    1. for 16″ (305), it’s 2″
      for 16″ (349), it’s 1 3/8″
      for 18″ (355), it’s 2″
      for 20″ (406), it’s 1.3″

    1. No, that size needs different rack and mudguards – Velo Orange make some 20″ guards, which should work with some tweaking.

    1. To change when size, you need a rear gearing kit (either Alfine, Enviolo or Rohloff) and front and rear disc brake kits – so the prices depend on which kits you choose, but would start at around £1300.

    1. Adding a rear disc brake is easy, as all my rear frames and hubs are disc-ready, so you just need the brake, adaptor and rotor. Adding a front disc brake is a bit more complex, you will need one of my kits which includes a new fork and new front wheel as well.

  12. Any concerns with mounting a pendix drive system to a 18″ Rohloff Brompton? Do you think everything would still fold okay?

  13. Hello.
    How larger is the chainring on a belt configuration compared to a standard one? Are you offering different diameters for different ranges?
    Isn’t concave folding considered unsafe for the belt? How do you address this issue? Is it recommended to avoid as much as possible to fold the rear triangle during long periods in order to preserve the belt?

    1. The 70t I normally use for the Rohloff is similar in size to a 54t chainring. Different sizes are possible, though 70t is the largest made.
      Gates updated their advice for reverse folding, and it is now commonplace on many bikes – it does not harm the belt when done properly.

  14. Thinking about ordering a Rohloff conversion kit with belt drive. Not sure exactly what is included in the price. Does the Rohloff equipped wheel include the tire and tube? Does the kit include a belt tensioner? Does the kit include the front chainwheel and rear hub sprocket? Are the Rohloff standard twist shifter and cables included?

    1. Tyre and tube are not included, you can just swap them over from your old wheel. The belt kit includes the tensioner, front and rear cogs, and the belt – plus the rear triangle is made belt-compatible. The Rohloff shifter and cables are included.
