I used them on alloy rims and they did a good job. Not as good as the green ones, but adequate. however, I was always very careful to check for any embedded pieces of metal before swapping to my carbon wheels.

hi
i use the yellow shoes on both alloy and full carbon rims and they work great

Not sure of the performance, but if you've ever checked and old set of brake blocks used on alloy rims, they have flakes of aluminium from the braking surface embedded in the pads. I wouldn't want that scraping across my expensive carbon rims.

G'day, I am using them on both alu and carbon rims and found them to be quite consistent across both. That said, the alu specific pads on my Campag Record brakes seemed to be firmer. I am getting use to these pads however and like the feel of them on both rims. Rgds, Steve

As far as I'm aware SwissStop yellow can be used on carbon and alloy, though given the price, would you actually want to do this.

I've got SwissStop green on my training bike (with alloy rims) and yellow on my TT bike (with carbon rims). Yellow on carbon actually seems better than green on alloy, which is not what you would expect.

Sorry not to be able to help more, but I haven't tried yellow on alloy.

Yes these are awesome for stopping power
Your shimano pads will feel like wood blocks

yes, they are a vast improvement. i am happy with the green ones i got.

yes

I bought the brake blocks including the shoes to guarantee the fit - only a couple of $ extra.

yes i use yellow on my zipps and i wont use anything else

G'day, I recently installed the full cartridge version on Campag Record skeleton brakes (pre-11 speed but I think that the design is near enough the same). Rgds, Steve.

yes they do they come with a curved block which go against the brake arm

2 pairs to fit front and rear.
