    Dura-Ace R9100 OT-SP41 Polymer-Coated Derailleur Cable Set

    Though the Shimano's Dura-Ace R9100 groupset is a marked departure from its predecessor, the R9000, the accompanying Dura-Ace R9100 OT-SP41 Polymer-Coated Derailleur Cable Set is largely unchanged: The stainless cables are still polymer-coated and the housing is still lubed with silicone. No surprise here, since Shimano spent all of its R&D time on far more important things like shifting, redesigning the hood shape, and increasing crankset efficiency.

    And what a job the Japanese brand did. Some of us are inclined to call Dura-Ace R9100 the best mechanical shifting ever. That admittedly gets the Italian fetishists up in arms, but even they admit there's a clean efficiency to it that never gets old. Until the cables do. The bike lets you know when it's time to replace your cables by getting sloppy on the cassette. Listen to it, and tidy-up your shifting—the new Dura-Ace is definitely worth it.

    • A cable set for Shimano's flagship mechanical derailleurs
    • Polymer coating and silicone lubrication smooth cable pulls
    • Keep the revised R9100 shifting as precise as possible
    • Compatible with Dura-Ace, Ultegra 6800, XTR M9000, XT M8000

    Reconsider your choice on this one.

    • Familiarity: I've used it several times

    I purchased this to use with my SRAM Red road derailleurs. Shimano gets a lot of accolades, in general, so how can you go wrong with this choice? Here are two possible issues: 1) The metal ferrule that goes at the cable entry to the rear derailleur has an 0-ring built into it. It is designed to keep dirt out of the cable housing, the exposed cable being close to the road. This o-ring fits the cable tightly, and really drags on the cable. If you just take the bare cable and run it through the ferrule, you can feel it buzz as it grips each winding of the cable, similar to taking your fingernail and running it along a wound acoustic guitar string. Not smooth at all, and hardly meeting the low friction objective of a new set of cables. 2) The polymer coating on the cable sounds like a great idea, but this coating seems quite delicate. Just the process of installing it had put little nicks in the coating which are visible as little "hairy" spikes of polymer sticking up from the cable surface. Yeow! I hope my cables last at least one full year (4-6 thousand miles). but I worry that such wearing polymer "hair" will build up and gum up the works inside the cable housing entry/exit points. A bike forum contained a moment that this is fine for a pro where the cables are changed often (every race???) but this is not appropriate for me.

    Prone to Abrading!

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    To be clear, the performance is in regard to the PTFE coated CABLE and NOT the housing. The housing is standard SP41 and can be purchased alone. The housing works fine. However, if you are thinking about complementing your bicycle with Dura-Ace grade cables, I would suggest steering AWAY from the Dura-Ace cables ESPECIALLY if you are running INTERNAL routed frames. The problem is that the PTFE coat on the cables is extremely susceptible to abrasions. Once abraded, performance diminishes. It will happen at all contact points outside of the housing, (ie. at the cable housing ferrules, at the bottom bracket cable guide, and at the exit of the cable from the rear derailleur housing. What this equates to is inaccurate shifts, poorly held tunes, and frustration. I got exactly one 75 mile ride out of this cable before noticing the cable would not easily release (upshift for the rear derailleur). This isn't as important downshifting because you can force the cable to pull. Harder to force it to release because it does not slide easily. I'd recommend a tier down and get optislick cables which do not have this coating, yet function very well.

    Super Smooth

    Super smooth cables that will keep your shifting feeling amazing. I use it on my dropper post as well.
