If you could do it over, how would you build your Brompton?

I see lots of people modding/upgrading their Bromptons. Ranging from $50 Ergon grips to a $1500+ Rohloff hub. If you could build your Brompton again, what would you choose to do right way, and what upgrades would you put on the back burner?

One of the things on my mind is: is $800 in Titanium for the superlight better money spent that $800 on other parts (Ti seatpost, Ti hinge clamps, SON hub, etc).

Interesting! Why is that? Is it very hilly where you ride? I have one pretty long hill (~ 1/2 mile), which is pushing me toward the 6. I'm tempted by the 2 only for simplicy and cost, but I feel like I'd regret not having more intervals in my gearing.

Are there local shops around? Test rides can be helpful.

I'm on Brompton number 3. Two were S bars, non superlight/titanium, 6 speed. One is a 3 speed M bars, has/d a rack & dyno front light. If I ever get a 4th Brompton; titanium/superlight option, 6 speed, L(fenders) or E(no fenders) type, not sure if I'll go straight(S) or higher M bars, front luggage block are some of the specs I'll go with.

I have the BSR , and at first I thought I'd go with a double chainring, and got a custom made FD bracket to do that..
it, black , clamped on.. used a braze on FD ...

Instead I fitted a Swiss Schlumpf Mountain drive Reduction geared 2 speed crankset, think 50t/20t chainrings..
though with a 54, the gear reduction is as if a 21.6t....15t hub cog, low 17" high 77..

I'd Sell my FD bracket, PM if interested..

I changed the chain tensioner pulleys to 10t Tacx..

replaced the front wheel to a new Schmidt XS dunohub, I did my own light upgrade I settled on B&M, not the ones they chose..

the new rims are better, drop center eases tire installation

New rear rim is directionally drilled , the old one same rim on both wheels..



Kool Stop pad inserts Salmon Compound..

Ergon GR3 grips, pu on some PC 700 Diacompe brake levers, I had ..


1st I got Sewn B Touring & then dry Ortlieb O bag, I got next..

Carradice SQR seat post mounted rear bag for more space..

I replaced the saddle, found the superlight option they offered a fizik vitesse..

If get a Stainless steel seat post rather than the Titanium Because I'm at 200#,,

I'd have to get the Ti Tubing of any seat post in a thicker tube-wall for my weight..

wait, I'm confused. Your profile says you own an S6L-X, but you said your S bar bikes are non superlights. On another note, do you own multiple B's or have you sold and upgraded for each one?

Sorry, I meant 2 were non ti models, one is.
1st B(gone) purchased in 2013 on vacation/holiday in Puerto Rico, around US$1450. It was a 2012 S6L raw lacquer. I liked it a lot; after 2 months I sold it on ebay for US$1350. I figure the only thing better than a Brompton, was a lighter Brompton. Only thing extra was a front luggage block and cover:

2nd B(still have) ordered from BFold of NYC around US$2500. It's a 2013 S6L-X(titanium/super light). Factory options: front luggage block, firm suspension. Aftermarket options: Brompfication ti seatpost, Primo Comet tires, Demano front bag, SRAM bar tape, Dura Ace 39T chainring, various titanium bolts swapped, etc:

3rd B(still have)bought a few months ago from NYC Craigslist for US$850. It's a (not sure of year) M6R. Factory options: dyno hub + light, front luggage block. Seems M bars are more comfy for me. Sold rack, don't use. Will sell dyno front wheel + light in the future; prefer battery powered light.

H bars. I'm happy enough with the bars on my M6L, but even though I'm a short guy I could use about an inch more rise.

I live on a pancake, seriously flat. Seldom, do I need more than 2. When I got the bike I thought more of using the gears when traveling.

If the option was available I'd have only purchased the Brompton frame and perhaps the stem riser. We've replaced EVERY other part on our Bromptons.

Why Brompton - the fold, pure and simple. If it were not for the compact (frequent air travel), and fast tool less fold, we would have chosen one of a multitude of other mini-velo.

Never owned one, would to. Dream would be a titanium one with those exposed brazes/welds *drool*
P type bars, sling a 6spd wheel in there and a T-bag on the front with all my camping gear in.

Excuse me, I'm gonna go daydream...

I'm rigged for self-supported touring with a M6R, -12% gearing, and T-bag.

Favorite add-ons in order: Vintage folding hairnet-style helmet, Brompton toolkit, X-roller, Alphabet Cottage Mini Clips, Ergon GP2s, Abus Bordo Folding Lock.

Favorite mods in order: drop grips in M bar's "U", backpack straps for T-bag, stuffing the frame and seat tubes with gear (spare tube, light, emergency stuff).

ToDos: Larger dia EZ-type wheels, 2nd 'greasy finger' chain ring for mountain climbs.

If I could do it again: Raw Lacquer, P-bars? (although drop grip in my M-bars is close yet better looking)

Completely happy with it as it is (H6L). I bought off the shelf (rather than to order) and only things I've bought since that I would have added to a custom build are the rechargeable lights (cateye - front in place of front reflector and rear under the seat) and also the toolkit. The bike does have the front bag mount which I'm not bothered about but useful to have in case I want to use it in the future.

If I bought a second I'd probably pick up a 3speed in white although white doesn't seem to be an option on the brompton website, but only to be different from the other one and to use for short journeys

Mind if I ask how tall you are? I'm 5'9" and am debating between M and H. How upright do you feel on the H, like Dutch, or not that drastic?

I'm just over 5'11. The H is fairly upright but I still don't feel totally upright. I had to look up 'dutch' and that seems vertical, and I'm definitely not like that. You can adjust the handle bars forwards too I believe, for more lean. It has the telescopic seat post and I pull the lowest section out as far as it goes and the second section (upper) is raised an inch or so.

I got my Brompton for a great price used, so I didn't get to choose the configuration.

I'd definitely go from three gears to six. I want the bigger gear range and and greater versatility, and less worry about hills. For a while, the Brompton was my only bike, and that felt like a real limitation. But now I have a second folder, with bigger wheels, lots of gears, and a wide gear range, so the gearing on the Brompton matters less to me. I now have a bike more suited to long, potentially hilly rides, and the B is more of an around town bike.

I might want S bars instead of M bars, but I'd want to do more test riding to decide. I also would be thrilled about having to use an S bag rather than the bigger C bag.

I Might add a rack, but I'd also want to try it out to see how much it matters to me in real life, in terms of rolling and what it can carry. Weight matters to me, because I have to schlep the thing up four flights of stairs.

I thought about upgrading the Brompton, but ended up buying a Tern instead, and the two bike combo works out pretty well for me, so I no longer feel much of a need to change. It would be nice to upgrade my B, but I'm not made of money.
