The stainless inner is also treated with a specialist fit 'n' forget polymer lubricant, and I've never felt the need to give them a blast of PTFE-based maintenance spray.
Sharp snips are a must for any cable guillotining, but especially where these are concerned because they fight back. If you're in any doubt about the condition of your snips, invest in a fresh set rather than risk ruining these pretty pricey cables. I accidentally pruned one with my generic workshop snips, the sort used for cutting zip ties, which resulted in a messy cut. A grinding wheel saved the day and my blushes, but you have been warned. A methodical, uninterrupted approach is best – bargain on an hour to get front and rear mechs sorted.
The outer is very stiff, creating graceful arcs where cables exit the frame stops and enter the rear mech, requiring some slight trial and error and trimming, which all tacks on time. It's worth the wait, though. Any new cable of decent calibre perks up shifts, but changes in every respect have become that bit more precise. Without any further dialling in, the front has skipped between 44 and 32 rings without hesitation, even when grinding up unexpectedly sharp climbs.
Riding through wet, gritty lanes and literally running them with zero TLC has made no impression on their performance these past few weeks. Beware that the outers are also quite harsh, especially when silty contaminant gets lodged in, so remember those rubberised cable cuffs and 'helicopter' tape where they rest directly against the frame.
Ultimately, I love these cables and rate them above other sealed units I've run in the recent past. Time-poor riders with higher end components wanting maximum performance with fit 'n' forget simplicity will be delighted.
Make and model: Jagwire Road Elite Sealed Shift Kit
Size tested: Outers 1700mm, Inners 2300mm Sts-Lf Coated
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Jagwire says: "The Elite Sealed Kit uses a continuous liner that seals the system completely protecting it against dirt, mud and debris. Available in unique frozen (matte) colors, this system offers the ultimate combination of protection and low-friction performance.
"To ensure the lowest possible friction, we developed a unique polymer-coated cable and paired it with Speed-Lube ultra-slick lubricant used throughout the liner. This combination delivers amazing performance and the precise lever feel you expect."
My feelings " Deliver truly superb, seemingly fit n' forget performance but at this price, something I would reserve for an Audax, mile-munching tourer or gravel bike with top-flight transmission."
Tell us some more about the technical aspects of the product?
* The continuous liner running from the levers to the derailleur offers much more protection from dirt and debris
* Ultra-slick polymer-coated cables are paired with our Speed-Lube to reduce friction
* New lightweight XEX shift housing is nearly 30% lighter than traditional shift housing.
* XEX - lightweight, braided steel strands around a Speed-Lube liner
* Sealed, Lubricated
* Jagwire sealed systems, available only in DIY kits, include liners that run continuously from the lever to the brake or derailleur. This protects the cable and housing from dirt, mud or anything else that can cause friction. But because the liner runs the full length of the cable, a specially developed cable coating and lube are used to keep friction to a minimum.
* STS-LF - pre-stretched, slick stainless steel spiral-bound cables with an ultra-slick polymer coating designed for use in Jagwire Sealed Kits
* Polymer-Coated or Polished Ultra-Slick Stainless Steel
* These ultra-slick stainless cables deliver the ultimate low-friction performance. Jagwire offers two options: An ultra-slick polymer-coated cable for use in our Elite Sealed Systems with continuous housing/liners, or a highly polished, uncoated cable that can be used with any housing and lubricant. These Elite level cables deliver incredibly accurate, smooth performance.

Rate the product for quality of construction:
Rate the product for performance:
Superb, ultra-precise shifting and, to date, seem truly impervious.
Rate the product for durability:
Difficult to say in the shorter term but standards of materials and construction suggest they should deliver excellent performance in the most challenging contexts with zero maintenance.
Rate the product for weight (if applicable)
According to Jagwire, its XEX housings are 30% lighter than 'standard' outers. An opportunity to save a few grams, if you've trimmed every last bit of "fat" elsewhere.
Rate the product for value:
These certainly deliver excellent performance, though probably best saved for a high-end groupset that racks up big mileages.

Superb shifting performance.
Tell us what you particularly disliked about the product
Outers were quite tricky to fit but this isn't particularly unusual by sealed system standards.
Did you enjoy using the product? Yes
Would you consider buying the product? For a mile-munching bike with top flight group, yes.
Would you recommend the product to a friend? Yes, though there are plenty of much cheaper but still good quality options.
