Brooks Flyer springs - where to get softer ones?

I did a search here and on google and the only information I came up with regarding changing springs for softer ones is to use the springs from a B67 or B73 (thinner gauge spring wire).

What other options are there?

I'd like to get a few different sets so I can tune the ride some.

Only place I know that sells Brooks Saddle parts (other than Brooks) is Wallingford Bicycle Parts. Give them a call or shoot them an email, great people to deal with.

Can't resist: Cheesecake Factory and Burger King. Eat enough, gain weight, and the springs will seem much softer.

Get a Cane Creek Thudbuster seat post . put the saddle that you have tried* and found the springs too stiff on it.

the seat post's interchangeable elastomers have a number of densities for various weight ranges.

*assuming this is not another pre worry posting without any 1st hand knowledge. (all too common here)

I really like the Flyer's springs. Mostly it's the same as riding on a B17. It's just when somehow I get caught hitting something on the road when I was too distracted to get off my rear ahead of time, the springs save me. I remember on my previous saddles, once I hit something hard, the resulting tenderness lasts a long time.

I've thought about the shock absorbing seat posts. That may be an option.

Just for reference here is my rig. I'm about 145-146lbs and the springs don't do much unless I hit a big bump. They help, but not as much as I anticipated.

That is all they are really intended for is to soften out the big stuff. FWIW I have about 65# more mass than you do and from the look of your bike a more upright riding style. If I rock back on the saddle I can compress the springs. I run my saddle even or slightly lower than the handle bars on my drop bar bikes. I currently use the Flyer on 2 bikes and have been very happy with it. I rode a B-17 for years on my race and touring bikes, and it was comfortable, the Flyer is a like an easy chair.

I've run across more than one post from people who believe that the springs on the Flyer dampen vibrations throughout the day not just the big bumps. They say that they are less tired and sore on long rides with the Flyer compared to a B17. The jury is out for me as mine isn't fully broken in after 600 miles and I haven't ridden a non-sprung saddle in a long time. Once the Flyer is broken in I might switch back and forth between it and a non-sprung saddle to see how much difference I notice.

May just be a lack of HTFU.. you really were a recumbent candidate .. just took the wedgie route..

not too late turn turn back

the springs don't do much unless I hit a big bump. They help, but not as much as I anticipated.
the expectation, on your part, was the problem.. they work as designed.


sell the saddle and get the regular 2 rail B17

Those people you mention might be heavier riders. The Brooks knowledge I've read believes that the springs don't do much unless you're 175-180 pounds or heavier. I'm 220 or so, and I really like the Flyer. I feel the springs flexing a little in normal riding, and of course they help on the bumps.

So I understand why the OP wants softer springs; the OP isn't heavy enough to get much out of the Flyer.

I have the Flyer; and a Terry touring saddle. I use a suspended seat tube. There is an internal spring that you can adjust as tight or soft as you want; many miles and still work great. I see one of the big parts accessary catalogs has them on sale for $20.00. harley

That's the conventional wisdom but I don't know if those cut-offs are experienced based or if they just appeal to reason. I do recall one bike forums post of a guy who noticed the difference at 150 lbs. I'm 180 but probably have less weight on the saddle than many because my saddle is slightly higher than my stem. I do notice the springs on little bumps.

Just to reiterate, there is a difference between the sprung Flyer and a non-sprung seat that I can feel, it is just that the difference is not as much as I anticipated. The leather saddle is a big difference in and of itself as it is "slick". I definitely need to get the saddle broken in, it is very new right now so doesn't fit quite right yet.

I am looking around for some other spring options. If I can get the specs on the stock springs that would help me out a lot - load rate per inch (or cm) of travel, max load, compressed length... I do see, though, that the last wrap of the coils is bent in and around the attachment bolts on each end. I haven't come across any spring offerings like that yet, but I am still looking (checked McMaster-Carr, lots of springs but none matching the design of the flyers). If I can get springs that are around 10-15% reduction jumps in load rate per inch (or cm) I think that would help me tune the ride, maybe having 3 or 4 sets. The trick is I need a starting point first. I can take the seat apart and make a jig to load test the stock springs. I'll work on that if I can't get specs from Brooks or elsewhere in a reasonable time (already emailed Brooks yesterday, no reply yet).

Cane Creek thudbuster suspension seat post
has a variety of density elastomer-rubber blocks
you use according to your weight... it reacts to ... 'thuds'

Body Float seatpost are more active in their springs action ..

I only own a Cane Creek , 2, 1 ST, 2nd LT.. But not the other ,

... here is a link . Note they offer a variety of springs,
where Brooks does not.


You can Wind a heavy steel wire into a coil ,
and then use a 'spring' heat treatment , to have it be a spring..

a metal artisan may make a couple springs custom, if you pay them enough.

Another 'if you have to ask how much it's probably not affordable' situation..

Thanks! Not sure that I can find seatpost for Dahon though. (Very long.)

Cane Creek looks interesting as it moves the saddle backward (I need it).

They make XL in oversize diameters; 30.9, 31.6, 33.9 https://www.canecreek.com/product/thudbuster-lt/

Or DIY, you create a telescoping 2 step seatpost ,
lower section cut off,square at top,
slot it for Clamp band, compression,

, seat post shim your ID of that tube , (Measure?)
That's the OD of the shim sleeve.

and its ID, a common 27.2, (or 25.4.?) seatpost..

clamp band holds it together .. Optional, a QR band clamp.

How do they measure length? Is it a tube only or the whole thing?

as a lightweight who bought a used flyer a few years back, I can say that at 135lbs, its taken probably a year of riding the thing to soften the springs up slightly.
And we are talking just a bit, enough though that when I hit a pothole or whatever, I can feel the springs flex more now, but Im still not convinced that it would be something Id use to go to Mongolia.

I swapped out the black springs on my Flyer Special for some chrome one, I think for a B67.

I can't say I've noticed any improvements in softness of the springs.

I like the eye candy of chrome springs compared to the original black ones as I feel it improves the aesthetic appeal (on a person level) for my black bike.

I sourced them sjscycles in the UK and the postage to Australia wasn't cheap but was prompt enough.

not us.. I have a Thudbuster LT on my bike friday, not a DaHon .

I can say LT mech takes up more top of the post length than the ST..

Dimensioned, data at website..
