At 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.

Jagwire's Pro LR2 rotors are a solid replacement for worn rotors and they're effective and quiet in operation. They look nice too.

The Pro LR2 uses a two-part construction with the steel braking surface of the rotor riveted onto an aluminium carrier. Jagwire says that this helps to keep weight to a minimum, but it will also help with dissipating heat from braking.

The rotors cope with heat pretty well; there are plenty of steep descents round here where dragging one brake can induce a bit of fade and that's certainly the case with these rotors, but not noticeably worse than the outgoing Shimano Ice-Tech rotors, and certainly not ever a worry outside of times I was deliberately trying to make it happen. They seem to resist warping pretty well, too.

Weight-wise they're light but not the lightest: our rotors tipped the scales at 138g per end, almost exactly the manufacturer's given weight (137g). For comparison, Shimano's Ultegra-level CL800 rotor is 114g in a 160mm; because there's a layer of lighter aluminium alloy in the braking part of the rotor itself, there's less heavier steel overall. Did I notice the extra few grams over the Ice-Tech rotors I took off? No, of course not.

Performance is good: the 'quiet, consistent stopping power' that Jagwire promises has been much in evidence. They're less noisy than the well-used Shimano rotors they replaced; you get a bit of chatter on light braking and when they're wet they squeak a bit, but they've been as well-behaved as any rotor I've tried in the very wet conditions we've had recently.

At £60 an end they're not cheap – an extra fiver gets you the excellent Dura-Ace rotors, and there are plenty of less expensive options. But they work well and they look nice, so they're a decent buy. It's worth noting that they don't work with some callipers, including Avid BB7s; check the full list before you buy.

Tell us how the product performed overall when used for its designed purpose

Very well: good, quiet stopping.

Tell us what you particularly liked about the product

Solidly built, quiet in operation.

Tell us what you particularly disliked about the product

Pretty expensive for a fairly standard rotor.

How does the price compare to that of similar products in the market, including ones recently tested on

RRP for Shimano's Dura-Ace rotors is £65 and Shimano rotors with this kind of construction are a fair bit cheaper. About the same as other third party options, eg SwissStop.

Use this box to explain your overall score

They're good rotors that are pretty quiet, but it's a fairly hefty price tag for what's a fairly standard two-piece rotor.

Overall rating: 7/10
