Hello All:
I have a 2012 Brompton - one made before the spider cranks were used. The 54T chainring is too large. I'd like to switch to a 44T without the much, as far as I can tell, higher expense (and trouble) of changing both the BB and the Crankset (and the left crank if I want it to look decent) to the spider/JIS type. I don't use my Brompton frequently, so the BB is fine.
I'm willing to trade my 54T one. Or if someone can point me to something that will work without being a kludge, that would be nice.
The closest thing I've found is this:
STRONGLIGHT ST55 Single Chainset :: £24.00 :: Parts & Accessories :: Components - Gears - Chainsets :: Spa Cycles, Harrogate - The touring cyclists specialist.
Which looks to be almost identical to the stock one I have now. The only trouble is that I'm not sure if it's ISO or JIS. Finding this crankset for sale elsewhere indicates that the newer cranksets of this make may be JIS.
At this point I might even be happy to find even the 50T crankset of the older type.
Any help would be appreciated!
