There are different versions but I opted for the BXP Flash Pro. They come as a full set of four brake pads and in addition to the pads you also get four new screws to lock them in place.
One of the reasons I have been looking to change over from the standard Fibrax brake pads is that although being pretty good they seem to wear pretty quickly, leave a black residue on the rims and are only okay in the wet. According to David and those who have upgraded, the Swissstop trump the Fibrax pads in all these areas.
Fitting them is a fairly painless affair and certainly no real difference to fitting the Fibrax pads. When I first used them in anger on my Original Orange Brompton I did notice a slight difference in stopping power but nothing that dramatic. It was on Sunday when I took part in 'The London Classic' that I could really feel the difference and their worth.
Sunday's London Classic started with rain which persisted for a good hour. The braking in the wet conditions and especially on the steep descents was where the Swissstop pads came into their own. They were brilliant in the wet. They didn't squeal and braking was firm, responsive and gave me greater confidence that I'd would stop quicker and more importantly safer.
By the end of the ride I was a convert. Yes they are a little more expensive that the Fibrax pads but this slight increase is worth it for the safety benefits. I for one will be placing an order for another set to so on my Titanium Orange Brompton!
