Excellent upgrade

ConsNot cheap, but you get what you pay for.

ProsGreat ride quality, fun cornering ability improvement

This is a great addition to the Brompton. I have a B75 and it could feel harsh at times. I weigh just under 70kg so was unsure which spring to go for, but went for firm in the end as I like a responsive ride. I have no regrets - the bike is so much better over bumps now, with seemingly better grip as a result. Cornering is also a lot more fun as I guess that's when the spring really comes into action. I've touched down with the pedals a few times as a result as I must be leaning further. Well worth it if you can afford it.

Its an upgrade and not essential but if you have the cash its well worth it.

ConsIts an upgrade not an essential

ProsSignificantly improves the handling

Having done a 1000km on my 2 speed Ive just changed to this. There is a night and day difference to the feel of the bike. As said by others already it makes the ride plush, removes all the bob and sharpens up the handling - cornering is particularly improved. I weigh 85kg so obviously got the firmer version.

Looks lovely, super stiff

ConsNone really :)

ProsEffective. Great look. Easy upgrade.

A very well made upgrade. Looks fantastic on the bike.
I am just over 70kg and have the firm version (3 spring). The ride is very firm - no discernible bounce at all, making the ride very positive.
Really easy to fit.

ProsRide, performance

This is the single best upgrade for Brompton performance, bar none, it cures so many issues with the weak rear axle on the bike. The improvement in ride is dramatic.

I bought the Firm as an 81kg rider, but I’m now also tempted to try the Soft. It is vastly better than the stock Brompton part and very easy to fit (10mm socket only, if I remember correctly).

The more compliant rear axle helps to overcome the inherently weak rear axle due to the very rearwards rider centre of mass and the small tyres. Not only does ride improve, making it more comfortable, the increased stability allows for more aggressive braking and cornering, and some ride can be cashed in for higher tyre pressures.

There are no negatives to this parts. It is also the best value for money Brompton upgrade.

Good, but softer than expected

ProsLooks, Function

I went for the harder version. The spring looks amazing. Certainly adds a more bling to the Brompton. The ride is good, but a little softer than I expected.

Spring on rough surfaces

By B

05 Jan 2024

Will the Scrowave spring make a ride on rough surfaces, like cobblestones, feel less bumpy compared to the stock Brompton suspension? And for this purpose, should a 68-72kg rider go for the soft or hard version?

Thanks!

SJS Customer Service:

Hello & thank you for your enquiry.
I my opinion, the Scrowave will make the ride more plush & smooth out road imperfections as well as sharpening up the handling / cornering overall.
The ride will become more positive with no discerning bounce.
To achieve this I would guide you to a firm / hard version.
Hope this helps.
Kind regards, pc 5/1/24.

I’m about 70kg - should I go for firm or soft?

By Charlie

11 Sep 2023

My weight fluctuates between about 68kg and 72kg. I usually carry front luggage. I like to ride quite fast :)

Should I choose the firm or the soft option?

Thanks!

SJS Customer Service:

It would depend on the feel you want, I would err on the side of caution and go for the firmer spring. SK 13/09/23

Can I use this with a pre 2017 S2L. I am 95 kg so I presume I will need the stiffer version?

By Rennie

13 May 2023

SJS Customer Service:

Hi
Thank you for your enquiry, yes this will work with a Pre-2017. We would recommend the Firm option based on your weight.
Kind Regards. JP 15/05/23

Can i use this with T line? Version type?

By Rine

28 Mar 2023

Is this compatible with T line? What's the latest version that you guys are offering?

SJS Customer Service:

Thank you for your enquiry, no sorry this is not suitable for the P or T line as they use a completely different design of suspension spring.

Can I use this with a P Line series ?

By Gavin

14 Aug 2022

I purchased this to go on my p line Brompton, However, when I am trying to install it, the nut just doesn't seem to be able to catch the thread. :/
Also, when installing it I tried to compress it by folding it into the Brompton, and still I couldn't

SJS Customer Service:

Sadly this part will not suit the P line Brompton,

Hi, do I need any other parts like bolts and nuts with this?

Scrowave spring

By Hugh Salter

16 Sep 2019

If the Scrowave spring is made from mild steel, surely it must be treated in some way in order to prevent corrosion ?

SJS Customer Service:

Hi there,

It probably has been treated in the manufacturing process, unfortunately we don't have access to that kind of information im afraid.

Thanks.

How would this perform if it was fitted on a Brompton Electric. Would there be any advantage ?

By David Burgess

17 Aug 2019

SJS Customer Service:

It is stiffer and plusher, whether fitted to electric or normal Brompton it is a higher quality product.

Thanks - 19/08/19

What materials is the spring constructed from?

By Hugh Salter

SJS Customer Service:

Hi,

it is made from general carbon steel.

what's the max weight it can handle :(

By Steve Vano

05 Jun 2019

Im 120 kg at the mo, slowly shrinking lol

SJS Customer Service:

Hi, it will probably compress too much with 120 kg to be effective as suspension. Thanks 07/06/2019

Firm or Soft?

By Canberk YANIKDERE

31 Oct 2017

Hello, I am 97 kg. Can i buy soft or i must wait for firm one?

SJS Customer Service:

Hello,

We would recommend getting the firm one.

Thanks.

I'm 71 Kg, which should I get, soft or firm?

By Dan

11 Aug 2017

SJS Customer Service:

Hello,

You do fall in to the category of the firm one, so we would recommend that one. However if you wanted to go for the soft one it should be ok as it is on a couple kg over, but we have not tested this so we can not say for certain.

Thanks.

What is the weight saving on original?

By N Hare

05 Aug 2017

SJS Customer Service:

Hi, there is no weight saving. The Scrowave is 54g heavier than the standard and 57g heavier than the firm Brompton rubber bumper. However there is an improvement in ride quality. Thanks.
