Brooks makes great saddles, but most of their other branded stuff is outsourced. It appears Ergon tried to dress up Brooks-branded grips with metal stickies over plastic end plugs. You'd be better off just using Ergon's standard plastic plugs.

If price is of no concern, you can try the Brompton Butterfly.

That's the conflict and you want to reduce the weight of your Brompton. Personally I don't like Brooks because they are too heavy for me. Not to mention they are expensive and outsourcing most of their products to other manufacturers. Ergon GP1 sells for $22 on Amazon but same design with Brooks logo it sell $80.

Anyway, I have a 6-speed Titanium Nickel Edition Brompton and currently the weight is about 8kg. Here is my upgrade list.
1. H&H carbon seatpost.
2. Fizik arione 00 saddle.
3. Titanium stem
4. Kojak tyres (this tyre saves a lot of weight)
5. Tune crankset
6. Carbon tensioner
7. Carbon S type handlebar
8. Carbon wheels

Cool list of upgrades.

Which brand is your titanium stem? And the wheels?

Also, would a titanium main frame be safe? EasyTi Titanium Ti CNC Main Frame for Brompton Folding Bike | eBay

Although, can you call it a Brompton if you replace the main frame?

I have been thinking about the same recently. Rear triangles and forks has been available for some time but they are not super heavy from the start. Main frame and stem is a lot of steel and should be fairly easy to swap out but I remember from reading about the frame on Ebay that one place they said one year warranty and further down on the same page 2 or 3 yrs (can`t remember exactely). At that price I would like more than one year warranty!

I was also thinking "can I register my bike on the Brompton site or put a Brompton stickeron it"? On the other hand maybe better to not have a brand name hoping it would be less interesting to steal.

If I did something like that I would paint the titanium parts to hide them. Call me paranoid but I would sleep better at night.

The Brompton folding frame is the part with the serial number on it. I don't see how it qualifies as a Brompton anymore if the frame is replaced; now it's a replica.

Just like Steve Parrys Ti Brompton is not a Brompton but still that is what we call it

I don't really recommend you buy from that ebay seller from China. I ordered one Brompton stem from him and waited over six months. Not to mention the quality is very poor once I got it. I had to spend another $300 at HomeDepot to buy some extra tools to make the stem works.

I have a full titanium frame Brompton bike that I ordered from Taobao, which is also from China, but not the same buyer from ebay you link. On a scale from 1-10, I gave it a 7. It is very light indeed but they are not 100% Brompton parts compatible. You just need some tooling to make it works. They are all 100% handmade so I guess it is what it is. I know they ship a lot of Ti frames to other countries in Korea and Japan but didn't see a lot of complaints from them.

My instagram ID is charles_ciaobu, you can find the ti bike info I post there. Just in case you interest.

You have some very cool pics on your Instagram! How did you make your stem work? Anyway, I don't see any sellers offering Titanium H stems, so I guess it's out of the picture for my case.

(It was my sweet spot between weight and looks. I also looked into the Berthoud Galibier, but I didn't like how the plastic piece on the backside looks. The Brooks B-series are too heavy. The Brooks Cambium I really like, but all the titaniums are black, which is a color I don't like.)

What other mods (specially weight-saving mods, to offset the saddle and grips) would you do if cost is not a concern?

I'm considering getting a carbon or titanium seat post, but I cannot find many reviews of their effectivity and safety. Also, I'd go for Brompfication for their reputation, but their production is halted at the moment. I've seen H&H offering both Carbon and Titanium ones (https://www.ebay.com/i/192125533648?chn=ps&dispItem=1). Does anybody has any experience with them? I'm tempted by the carbon one due to a very low weight, but I'm worried because I read in a review that it cracks if over-tightened, and it slides if under-tightened. Any thoughts? (Note that I weight 140lbs).

Any other mods that you'd recommend?

Thanks!
A few:

1.The H&H titanium racks (sold at NYCE, and elsewhere) are very nice and light. Mainly it makes a better rolling platform, but it is a good rear rack when you may need one. You can add it to a "L"-Brompton easily. If you want to go with steel, Nitto makes a beautiful Brompton rack in silver and also black. CrMo.

2. The anodized 77mm rollers look good and have stronger 6mm bolts.

3. I can recommend the Selle Anatomica new type saddles: leather, center relieved, aluminum and stainless frame.

4. An upgraded elastomer damper: the scrowave washer springs are good as are the coil spring-type dampers.

5. Lights. The Schmidt XS dyno hub and Edelux II LED headlight and the Schmidt rear generator lamp. If you don't want a generator, look at the NiteRider 950 rechargeable.

the J bend spoked Schmidt XS , has 2 newer dyno hub products that are smaller and lighter..

Radial , built wheel, they have been designed to use a straight pull spoke, which they got butted..

the 2nd , semi radial, pairs the spokes at the hub, that slight kink allows a spoke to be replaced in the field if needed,
because though still a straight pull spoke the bend would, logically, not have the head and nipple turning together..

Thanks for the further suggestions! I've already got the SON Dynamo, and I'm pretty happy with it, not planning to change it (it's 0.8 lbs as opposed as 1.2 lbs for the Shimano).

I just ordered a J&L Ti handle bar, and I'm planning to order a Ti seatpost too. I'm still debating if I should try a carbon seatpost, but I'm afraid of failures, and some of these Chinese brands looks very shady.

I also found carbon mudguards: https://www.aliexpress.com/store/pro...833893641.html I don't think they'll save much weight, but I may give them a try.

Search Instagram for "vostokbike". My wife's Brompton is the Turkish Green.

Currently massively under geared: custom chain rings (CycleUnderground) are due this week & 13T sprockets coming from Rohloff.
