Looks like a great deal for a popular budget derailleur
Free delivery at £20

Shadow Plus: Shadow plus features a super low profile design and optimised slant angle for super
light shifting action. Shadow Plus uses a chain stabilising switch that when on will reduce chain
bounce in rough terrain maintaining more stable drive and shifting.

Single Tension Spring: Prevents contact with the chainstay resulting in a silent ride.

Direct Cable Routing: Direct cable routing prevents snagging from any trail side hazards.13T

Pulleys: 13T pulleys and decreased derailleur
tension prevent high chain tension in low gears.

Springs: Strong return spring for a positive
shifting feel. Top normal spring uses the spring to select higher gear

    Also works on 12s too

    Great price, almost tempted to get one as a spare if it works with 12 speed.

    The official word from Shimano is that this is only 11 speed compatible, so YMMV if you try it 12 speed.

    Those cheapo Deore parts are an amazing low budget way to give an old neglected bike a second life. Hot.

    Need a new chain and a shifter. I went the whole hog and changed the front chain set and crank arms but that's optional.

    Is it common for these to go? It's the exact one on my Siskiu DSE FS. Wondering if I should get a spare.

    Depending on your: riding style/type, miles and weather. Go roughly through two/three a year, but if unlucky could replace one after one ride. At this price get them because the jockey wheels would nearly cost you the same.

    This will go great with the pedals i bought the other day. Some day will eventually have a full bike.

    Looked at the picture and thought it was some sort of cyber or steampunk seahorse.

    Any cheap deals on 11speed road rear mechs?

    Would this work on a 9 speed shifter and cassette replacing an Altus shadow 9s?
    electriclinux's avatar
    No you would need a 11 speed shifter and a 11 speed cassette
