Jobst Brandt warned never to use them!
Sheldon Brown warned never to use them - even on a tandem!
They can brake a tandem so hard that the rear wheel will lift!
When Suntour bought the rights their lawyers banned them from going on the front of any bike what so ever!
Even the guy who posted "But Sheldon, they're fine for my tandem, I wouldn't have anything else!" refused to have them on his mountain bike or tourer!
Yes, I bought a pair - they're front and rear specific - of the notorious original Pedersen Self Energizing Cantilevers in their funky coloured CNCed glory! One is anodized blue, one purple. The canti arms are on a helical screw so that wheel rotation pulls them them together, boosting braking power.
After Chris put the idea in my head when he saw the Suntour rear-only version for sale, I did some checking around. These things do have a reputation for bestial power, but the people who got them to work properly also said the modulation was as good as any canti and they're great on a mountain bike if you're not an idiot. They can squeal extremely loudly, but my research says that's curable. What they need is dismantling for lubing every year or two, the same careful set-up as any cantis, and - ideally - brake boosters.
If anyone is interested, I believe the US ebay seller may have more for sale shortly, and he's willing to post to the UK.
BUT you shouldn't put these on a suspension fork - unless, I suppose, it has an anti dive barking feature you trust. Possibly. A diving fork combined with the SE system can create a feedback loop which results in braking power increasing for the same hand pressure and an instant wheel lock.
