ConsSlightly expensive
ProsWorks well
This spring is good, with a caveat: Its aluminium end cap doesn't compress around the upper suspension plate's brazing beads as the Brompton polymer suspension block does. The cap sits on top of the beads - on my Brompton, too far from the USP to hold the flanged white nylon washer firmly in the USP hole. With 10 months use, the unshrouded bolt thread has slightly enlarged the hole on one side. I've fabricated a plastic spacer 15 mm Ø x 1.25 mm thick to sit in the end cap's recess beneath the white washer, holding the washer hard against the USP.
Out of curiosity, I recently greased the interfaces between the spring's three leaves. Unexpected result: the bike seems to want to go faster! Can't be buyer's euphoria - I've had it 10 months.
I can only speculate that the greased spring may be helping the rear wheel track the road surface better, transmitting power more efficiently.
Recommended - but make sure the white nylon flanged washer is held firmly in its hole in the USP.
If you buy one thing for your Brompton, buy this...

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.

Does this item require any routine maintenance, e.g. lubrication ?

For example where the hops of the “waves” rub against each other when the springs are under load.
Hi there,

No maintenance really needed, mine is about 700 miles old and working perfectly even with the classic English weather!

The best upgrade I made to my Brompton!

Thanks
Firm or Soft?
By

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

We would recommend getting the firm one.

Thanks.
I'm 71 Kg, which should I get, soft or firm?
By
11 Aug 2017
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

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.
