Brompton 3 / 6 speed wide ratio wheel

The Brompton BWR (Brompton Wide Ratio) rear wheel kit contains the following:

Sturmey Archer / Brompton wide ratio (BWR) 28 hole rear wheel with double walled rim
Rim tape - yellow for double walled rim (QRIMTAPE-DW)
Gear indicator chain (QGICH-SA[2]) for alloy shell hub
Fittings (nuts / bolts / washers)

Colour: Silver (The BWR wheel is now also available in black)

Normally this wheel is used as part of the Brompton 6 speed wide ratio setup, but based upon your selection of sprocket set, this wheel can be used as 3 speed or 6 speed.

(6 Speed also requires that you have a derailleur chain tensioner)

Brompton Q part code: QRW3SS-BWR

28 spokes
Valve hole to suit 8mm Schrader / car type valve

The Brompton BWR wheel was originally introduced (specially made / licensed for Brompton) by Sturmey Archer in 2008

I got this as a replacement for my standard hub wheel where the rim cracked after one too many potholes.
The wide ratios make a big difference and brilliant bikes even contacted me to offer to fit the tyre, tube and sprocket that I irdered at the same time so I swapped wheels I've and was back on the road in ten minutes

on 18/11/2018 Hi, Brompton 3 or 6 speed rear wheel with wide range Sturmey Archer hub (Reference: QRW3SS-BWR) I'd like to know approx weight and dimensions of this item. I would appreciate your reply. Thank you Abdullah Answer:
Hi The wheel dimensions are: Rim diameter: -36cm / 14.2in. Rim width - outside: 2.3cm. Width at axle (axle length) : 148mm. Weight (approx) - complete with sprockets and nuts / washers: 1.4kg (including some dirt, some internal grease, rim tape and a very worn rim). I hope that is useful - if you want to know more just let us know.
Asked by Andy Gibbons
on 22/02/2019 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

on 18/04/2019 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
Asked by Charles Ferrar
on 14/06/2019 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)
Asked by Pedro P Anto
on 20/06/2019 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
Asked by James Teape
on 18/08/2019 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
