I have decided on a M6L-X in Raw Lacquer.
I am having a tough time deciding on a saddle. I always have trouble with normal saddles, with the numb-effect.
1. Do you know if the Brooks B17 is a comfortable saddle? (maybe the Imperial variant?)
2. I kept reading about the ISM Adamo. Can they be fitted on a Brompton? I am thinking about the Adamo Typhoon. My only issue with them is they look very weird. I want something that looks a bit more classic, but I want the comfort and light-weight too.
3. Rido R2?
4. Selle SMP TRK?
5. Maybe a ThudBuster would help too?

Except the Brooks which I know can be fitted on a Brompton, what about the rest of them? Do I need a special attachment or something?

The Brompton has a standard saddle clamp, so you can use any saddle with normal rails.

That's good to know thanks. I ordered the brompton to come with the Brooks B17 special saddle. I hope it will be ok. If not the hunt for a saddle will begin.

And now I wait

I have a Fizik Vitesse (There is a model* that was optional with the earlier some Ti 'X' parts version) On Mine.

B17 has plenty of fans.

I spent years on various "modern" saddles before trying a B17. I should have started there..it's the only one I can ride more than 10 miles in comfort. It'll take some time to break both you and the saddle in, but chances are good you'll end up loving it.

B17 all the way. I have a C17 on my H6L and like it but it's not as comfy for long rides as my B17 Imperial which is on another bike.

I use a C17 for long rides:

B17 works great for me. I've put Brooks saddles on all my bikes.

I use the narrow Velo-Orange leather saddle model 106 on my Brompton S1. I have used it in 100 degree heat and in more moderate temps for 2-3 hours at a time without any problems in terms of saddle sores, numbdick or any other issues. It seems more stoutly made than my B-17 narrow as the leather is bonded to some kind of mesh and the saddle is joined underneath in the middle to prevent splaying. the rails are a little longer than a Brooks so you get a bit more fore and aft choice. Mine is the honey color which I think looks nice with Ergon cork grips. I like the saddle bag loops on both the Brooks and the Velo-Orange saddles. The Velos are 110.00 right now on VO although they have 20 % off until 12/14.

I have a B67 on mine. It is very comfortable and looks great.

Ah, an excellent saddle which should work well on a Brompton with the taller bars. I have one on my cheap no-name upright-ish electric folder.

Saddles are such a personal thing. Some love Brooks others hate them. I had a B17 but on a non folder and hated it. Sold it after six months of daily use. It just didn't work for me.

On my Brompton I decided to try the B17 again, not because I think it will be comfortable but it because it looks good. It just suits the bike with copper rails and rivets. My feelings are it is just a saddle, I don't love and I don't hate it. Neutral is the best description.

On my Rivendell I have a B67. I love this saddle but as Joe Remi said above it is best for bikes with bars higher than the saddle. The only drawback to this is the weight. It weighs almost two pounds.

Even the B17 on the Brompton adds a lot of weight. I think 1nterceptor has the right idea with using the Brooks C17.

The saddle I love and had it on two of my bikes is the Specialized Avatar in 155mm width. This was my go to saddle for daily commuting.

In the end I think it is about trial and error when you get a saddle. You hope the best on the first one you choose. Good luck.

I have the B17, B72 and B67 and I must say the B67 trumps them all IMO. Especially if you enjoy the upright riding position. I think many here prefer the slightly more forward S-type posture, so the B17 makes sense.

The B72 is a solid middle ground with a similar wide shape as the B67 but noticeably lighter. If I ever decide to put my M2R on a diet, I'd switch the B67 for the B72 in a heartbeat.

I have B17s on two bikes with drop bars and they are very comfortable on those bikes. I have the M bars on the Brompton and I am short, so it is definitely more upright. I haven't tried a B17 on the Brompton, but maybe I will swap one over there one of these days to see if it will work.

The Brooks saddles are nice - I have enjoyed them in the past - but they are very heavy, which may or may not matter to you, and they are not cheap but perhaps, if you are buying a Brompton, that is beside the point..

The standard Brompton saddle is actually quite good. I have done 60ish mile days a couple of times and it worked fine. It is much lighter than the Brooks but doesn't say "I am leather and have copper rivets". It seems that many buy saddles based on appearance, which is folly in my opinion. But if your time in the saddle is short, it really doesn't much matter what you ride, so maybe appearance would be important. And yes, for many, they are very comfortable.

What makes a Brooks saddle comfortable for long rides?

The fact that leather will stretch and fit your butt after a while?

Is there a lighter (and cheaper) option?

as said above.. Brompton Saddle Vitesse - QSADVIT - £16.00

it's not a Leather Hammock .

Brooks also sells a Titanium frame B17, if the frame weight is desired to be reduced, the leather will still weigh the same,
It will cost More, not Less.

B17. no need to break-in. comfortable out of the box.

cinelli unicanitor. plastic but surprisingly comfortable.

original brompton saddle. not too bad. quite confortable.

El Cid - I just can't see why you would splash the cash for a ti Brompton and put a heavy Brooks saddle on it. Don't get me wrong, they are beautiful and comfortable saddles, but not the best choice for every application. The standard Brompton saddle is good - check it out. Another alternative that has worked well for me (over 200 miles in one day - but not on a Brompton) is the Terry Fly Ti - it is quite lightweight and for me, very comfortable. It is half the weight of the Brooks B17.
