    If using the BWR hub as a three speed, what are the ratios please? I currently have a 44 chainring and 15 sprocket. Also, does it require an new trigger shifter? Thank you. Answer:
    The six speed (using a 13/16T combination) with reduced gearing (44T) front has the following ratios: 1st 2:32m / 2nd: 2.86m / 3rd: 3.64m / 4th: 4.48m / 5th: 5.71m / 6th: 7.03m. Changing to 3 speed BWR you could choose 13T or 16T (or 12T). 13T would give you equivalent to 2nd, 4th and 6th. 16T would give you equivalent to 1st, 3rd and 5th. The shifter is the same as a standard 3 speed as the pull ratio is the same

    can i use this with my new 6 speed brompton 2019 model. Answer:
    Yes - the 6 speed Brompton uses a 3 speed BWR rear wheel in combination with a 2 speed derailleur to give the six speeds

    I have a 2007 Brompton S6L. The caged bearings in the SRAM hub have failed so I am interested in options for upgrading from the SRAM hub to the BWR, staying as 6 speed. I note that the upgrade kit is listed on your website as no longer available. Is there an option for me to make this upgrade? Answer:
    Changing to a BWT wheel would be a good option - you could even use the same trigger. The only other thing you should need is the sprockets (it comes with the gear indicator chain with the wheel)

    Yes. I will be pretending to go on tour to Spain soon to do "El Camino,", around 475 Km.Most of the road has, I think a lot of potholes..My wonder is, how good the wheel of my Brompton will perform in that terrain? Most of the people who do that tour used mountain bike with suspension.Will the Brompton perform adequately? Thank you for your answer. Answer:
    We are always told by Brompton - it's not a mountain bike - so be careful if you try it on a Brompton

    is it possible to have any gearing other than sturmey archer? Answer:
    The only other option is the two speed or one speed (from Brompton) - if you contact Kinetics in Glasgow they also offer a Rolhoff option

    I have an older m3r with a short wheel base would this be suitable and what other parts would be needed to change it to 6 speed ? Thanks John Answer:
    This wheel is for a Brompton. It takes Brompton sized tyres which are XX-349 ETRTO
