At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
SwissStop's Disc 34 RS Pads are a great upgrade for any bike facing hard conditions. They remain silent in grotty weather, wear slowly and while they're more expensive than the stock pads, they don't cost a fortune.
SwissStop has provided the upgrade of silence with its Disc 34 RS pads. It might not sound like the best upgrade, but when you've heard the howl of contaminated disc brakes, you'll pay anything for a quiet system.
The 34 RS pads use an organic compound that, while offering quieter braking than the Shimano pads they replaced, don't seem to offer a noticeable difference in stopping power – and the Shimanos are slightly cheaper. That said, they performed well on steep descents, allowing me to slow down rapidly from high speeds. They also offer loads of modulation which further improves their performance in the rain.
Installing the pads is simple. Just pop the old ones out and slot these in. You'll need to do some bedding in of the pads but this is quick to do on a short ride. I just pulled hard on the brakes when heading down a couple of steep hills.
The pads are designed to fit all the latest Shimano callipers from Dura-Ace down to Tiagra, along with Shimano 'non-series' brakes. Once fitted, I can't say that I've had to touch them. It makes the pads very easy to live with.
As my testing has been done during a horrendously wet winter, the conditions have been perfect for exposing any issues with premature wear. Happily, the 34 RS pads seem to be holding up brilliantly.
The combination of silent braking, low wear rate and lack of maintenance needed makes these pads a great upgrade for a bike that is likely to see the rain. There aren't many upgrade options for your brake pads but thankfully, this is a very good one.
Quiet in the wet with a low wear rate – a very good upgrade
