How we test

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.

The hollow forged alloy crank (after flirting with carbon, Shimano Dura-Ace cranks are now fully alloy again) is matched up with a hollow outer chainring to produce a crankset that’s a tad (15g) lighter than before. It’s also said to be 20% stiffer although, in use, you’ll do well to notice. Even if you’re a big rider pushing a big gear, the difference is tiny – but, hey, everything helps so we’re not going to argue. If you really want to get out your anorak and magnifying glass, you can take a look at the slightly altered tooth shape which is designed to give better contact and power transfer. The crankset comes in a whole range of chainring size options including, for the first time, a 50-34T compact design for a lower set of gear ratios.
