Looking for a replacement chainset for my wife's Pashley - gearing is set up for someone who only ever travels downhill and can produce 400+watts for long periods.
We can't change the weight of the bike or the hub gears but a smaller front chainring might give her a fighting chance.
Basically this but with the smaller ring.

Can you not just use the one you have and stick a larger cog on the back?
As far as I am aware they all use the same three lugged cog that sturmey use.
Try Spa Cycles, they seem to have a lot of niche stuff. Or SJS.
Depending on the chainline and current axle length you can run any old 4x 104bcd MTB triple chainset with a cheap ebay ring in the middle position.
Try BETD.
Spa cycles. cheap, light, good looking, all teh options. Got one for the wife's bike, going to get one for my commuter too. Get a triple and put a chainguard/ trouser guard on the outer tabs.
It' so bloody marvellous spinning into town on her bike - few pedal strokes of leaving the house, think - "Oh, must tuck trews into socks.... No! Don't need to! Ha!" Bit like going for a ride in the rain with full mudguards. Bang on for a Pashley. Unless it's got a chainguard already?

maybe even two guards, on inner, one outer, get a non-narrow-wide chainring?
not chromed steel, though, so you can ignore all of that ^.
Thanks everyone- few to look at. I did consider rear cog swap but it's already on somethign like a 20 and a 30% reduction would need 25-30t one which I wasn't sure was available for a hub gear but I'll check.
Biggest issue seems to be BCD and minimum chainring size on a lot of the 'road' options so I'll look at a double maybe and dropping the big ring off - hopefully chainlines will be ok as I don;t want to be mucking about with BB axle length if I can help it.
(thanks NedRapier - I'll look at that as a solution)

25t in stock here for £2.99
Alloy not steel but SunXCD chainsets are amazingly retro looking. Go with cloverleaf chainrings for even more style (although these are available if fewer sizes).
Going to give this one a go I think - 34t but looks like I can fine tune with the rear cog to a certain extent and this is cheaper than a separate crankset/ring/bolts purchase.

Not chromed but I can polish them up further.
