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 meanGood scores are more common than bad, because fortunately good products are more common than bad.

There are a couple of big changes out back. First, you get a carbon pulley plate that brings down the weight (16g overall). Second, the new rear mech is compatible with cassettes up to 28T. The total capacity (the tooth difference between the two chainrings plus the tooth difference between the biggest and smallest sprockets) is now 33T – so you’re unlikely to feel the need for a triple. Once set up and bedded in, we had no troubles at all with shifting either up or down the cassette – all very precise and very definite in both directions with no need for any tweaking during the test period. What more can you ask for?
