Lower gearing for all Bromptons (1,2,3,6, 8 and 11 speed)

 

This is probably the most asked question I get about the Brompton bike, if you have got the smallest Brompton chainring (44t - standard Brompton chainrings  also available below) and the largest rear sprocket for your model and you still want lower gears then I can supply (and fit if required) two new options, Stronglight 40t and Alfine 39t.

Stronglight 40t chainset (fixed) a smaller chainset by the manufacturers of the Brompton chainrings, the right crank arm is the same style as the pre 2013 Brompton so you can either retain your left crank with the Brompton modification to stop the folding pedal touching the frame or fit the new one supplied with a modification to do the same. It will use your current bottom bracket cartridge. Supplied with a bespoke laser cut polished or black aluminium chainguard £49.99. U.K p&p £1.95.

Shimano Alfine 39t chainset with chainguard, giving the lowest gear and upgrading to outboard bottom bracket bearings (included), the left crank arm has been modified to retain a pedal stop function, £89.99. U.K p&p £1.95.

Nb. not suitable on 11 speed conversion,

Or NuVinci conversion

Brompton 11 Speed conversion

 

Fitting the Alfine 11 speed hub to your Brompton requires the widening of the rear frame (steel), with my jig this is done cold which avoids any paintwork damage, all the other mods are done to retain a Brompton look, rim options including pre 2013 style and newer double wall rims available, suitable for M/P/S/H- type handlebars (M/P/H- types need a little adjustment of bars - something many Brompton owners already do to get a more comfortable brake lever angle - to allow for the bulkier gear shifter so will increase the width of the folded bike slightly)  it retains your Brompton chainring, gear ratios are:

409%

With 44t chainwheel 1.67m - 6.86m

With 50t chainwheel 1.91m - 7.98m

With 54t chainwheel 2.07m - 8.62m

Or with lower gear options (details below)

With 40t chainwheel 1.52m - 6.38m

 

Fitted to your Brompton the costs is £760 including new Velocity Aeroheat rim, hub and wheel build using new Sapim spokes, chain tensioner with mods, chain, gear control,Shimano brake levers and Brompton foam grips! Or upgrade to the new Selle Mano gel or ergo grips £30

gear ratios are:

360%

DISCONTINUED DUE TO LACK OF INTEREST

This hub has no steps in the gear range but is continually variable over the range via the twist grip shifter, super smooth, quiet and no internal maintenance required, has to be ridden to be appreciated

Notes on wheels

“Lite” is wheels built with Sapim double butted spokes (same as Brompton X-lite spec)

“Standard” is wheels built with Sapim plain gauge spokes

“Strong” is wheels built with Sapim Strong single butted spokes.

 

X-lite is front wheel built with the Brompton x-lite hub which is currently not available, Brompton are now calling their front wheel with standard hub and double butted spokes in a radial pattern x-lite, I build that wheel with double butted spokes, a 2 cross pattern and prefer to call it “Lite”
