How is it different? Sorry forgive my ignorance!

Well it does come in three attractive shades, and it does have a nice spring

It has a spring on the bolt to pop the clamp away from the clamped whatever as soon as you've loosened the screw enough. The standard clamp requires you to not only unscrew the bolt, but also manually pull the clamp out to free it. It's a convenience feature. Possibly a cheap DIY mod if you can find springs of the right size and compressibility.

+1 Chop the colours, one suits my raw lacquer lol!

Seems like a neat trick! I sometimes nick the paint if I open and close too quickly so this would eliminate that effect!

The clamp is also slightly longer on one side. So as you unscrew it, the spring pushes the clamp out, and the slightly longer side keeps the clamp oriented. It doesn't rotate around, so it leads to a much cleaner, faster clamp/unclamp method. Nice!

Unfortunately the company is only selling to the domestic market at this point, not internationally.

dremel+big spring=same effect. They should license it to BromptonProper. Like I should with my stem QR hack...

These guys do

quite stylish bolts as well...

Love my Kamoya clamps somebody brought me from Japan...

Currently, they ARE. bring sold internationally, viz. in Malaysia.

I am in Bangkok now and trying to contact Brompfication directly. They are sold through dealers but I like to meet inventors and see what else they carry or have in the works.

My question is how do the Thai-made (?) alternative titanium hinge clamps compare to the aluminum ones sold in Japan? And, on the face of it, I agree with the earlier poster - why not just add a spring to the current originals, whether real Brompton or knock- off. I am both fascinated and disgusted by the concept. How Romanian dictator - gold-plated toilets next!

Where do I buy Kamoya ones in Tokyo?

Been looking at these on eBay. Looks like the newest twist on these is that on the side of the clamp that is longer, they've imbedded a neodymium magnet so that the longer end sticks to the frame. I'm actually tempted to try it out, but $85+ is a steep price for admission.

Buy a spring , and file down one side of the stock pac-man and there you are..


this looks faster to spin

I cannot recommend these. See the 2nd last pic in the eBay description, showing the new and original clamp's inside side by side? You can see the Brompton clamp is wider in the middle while the new one is straight. That slight widening in the middle is there for a reason: It ensures that the outside corners of the clamp are forced together. That is crucially important for firm clamping. When I used a Brompfication clamp, I found the frame wobbled a bit. That clamp was the reason. Went back to the old clamp and all is right.

Has any one tried these Bike Gang They look to be a less expensive alternative but I can see the case for light springs.

haha! i knew it was only a matter of time before someone put out a version of the clamp with a kohler faucet handle


so many possibilities...



notice how, in the ridea knob, the left side is smaller and both sides are more ergonomic than in previous solutions we've seen. i suspect the next iteration will be the obvious, single-sided twiddle-knob.



design development takes time, even when the "ultimate solution" seems self-evident and obvious.

Has any one got the new frog clamp.....

I think this is the first time I've seen "frog" and "Brompton" in the same thread. Impressive.

I find it useful to have my thumb across the handle to snug the 'pac-man' down properly..
kitchen faucet is another story..

only brass, though. i'm currently working on one for keyven. of course, it will be much more aero and 3-d printed in titanium. probably retail for around 300usd.

Yes it took me a week to realize this. I thought Brompfication had given me a dud, but actually I had simply installed it wrongly. If only they worded their manual in a way the layman can understand

It may not sound like a lot, but the weight savings (minimal) and more importantly, the fact that the clamp stays aligned after unfolding really makes a big difference to the predictability of the fold. Plus, the look - shiny brass handle with black contrast clamp - is fantastic IMO.

Indeed, I will gladly pay double for such sweet, sweet bling for my Brompton.

How can we miss the frog style clamp lever (evolution ultima), working on it right away!

I did, and the pair of clamp plates come with two springs. you can even attach a leash on the Ridea lever to walk your brommie.
