Thanks for the compliments everybody!

I should have no problem finding a 130 BCD 40t chainring. But I really wanted to keep the "pants guard" thing.

Thor USA has litepro chainrings with integrated guards.

53t is the smallest. I'm looking to go down to 40t.

You can get down to 42 if that would work for you, well 45 actually unless you can use an oval chainring

Interesting. I sure wont be filing the frame. Do you happen to know what brand/spec cogs I would need?

On the 6-speed BWR: Shimano compatible ones. You can just buy a cassette and rip the cogs off it if you do not manage to get the desired sizes solo.

Thanks for the tip, but I'm somewhat loath to spend loads of addl $$$ on an already expensive bike.

Not to forget the additional weight (which is not neglectible) and the awkwardness of dealing with three different shifters for you then 12 possible gears. Technically sound, but heavy and expensive and hard to use (in combination with a six speed).

You already have two other bikes. Use them when you need the extra gearing. The Brompton is designed as a city/commuter bike, with the added side benefit its portability means you can chuck it in a train or plane to do some touring in faraway places. The compromise is the gearing, but for 99% of users that's more than adequate, plus has an advantage in that you see more of the countryside at the leisurely pace the Brompton enforces. I use the Brompton for mundane day-to-day stuff, plus the occasional holiday that involve aircraft, otherwise it's the 21 speed tourer for me.

One thing worth considering is what effect these mods have on the value of the bike if you want to sell it. I can't help feeling that the aforementioned 99% would want the Brompton as original as possible. After all, it is the iconic folding bike.

Yet many people do , a lot of companies exist to offer many aftermarket parts, in light metals, to them.

2-speed Brompton
 
A few years ago I purchased a 2-speed Brompton myself. Its great for commuting in the city because the 2-speed is low maintenance and simple to use. And with the reduced gearing can climb most hills that are common in the city.
If I was going to do touring or long distance riding Id most likely want around 8 gears or more on my folder.

avole 05-15-18 06:58 AM

But how many gears on your folding bicycle?

On ebay there is a 40t chainring with a chain guard for Brompton from H&H. It's expensive at $98.00.

My advice regarding these boutique accessory companies....if you see something you like from them, order it NOW while its still available.The attrition rate on these low volume products and the companies who develop and bring them to market is quite high.

Just saying.

So here it is with T Bag loaded on a 45 mi mixed surface ride. So far quite excellent!

Going to get a standard Sugino 39T ring.

Nonsense

Very well founded argument, I'm impressed. So - according to you - a Schlumpf drive weights nothing, costs nothing and dealing with three different shifters to get a straight line of gears is as easy as using a single shifter for the same purpose? Good to hear. Where can I claim my free Schlumpf-drive?
