I converted my bike from an XTR triple to a double chainring setup. I needed an E type mount to replace the OEM one on my carbon frame. This derailleur works great with my 24-38t XTR crankset. I just adjusted the cable tension and trigger shifter. It works fine. Less shifting and is more efficient than a triple.

Shimano makes solid kit, at pretty much any level. The more you pay, the lighter they get. I refurbished my bike from an old worn out Shimano STX-RC 8 speed with SRAM grip shifters, to a 9 speed Deore set up, so bought this cassette. It works great, is very solid, and didn't cost much money, shifts smoothly, I'm very happy.

Want to pay more money, get the SLX or XT model, it'll be lighter, and maybe get you more kudos from other riders, and it'll cost you a lot more money. That's just how bike components work!

Want to pay less? There aren't very many options from Shimano if you want a 9-speed drivetrain, other than the HG20 I think. That'll probably work great also.

I installed this to replace a 10 year old factory cassette on a Specialized Crossroads hybrid bike.  I ride a lot of big paths here in the Denver metro area with a couple being crushed stone and over time sprockets 3-6 were pretty worn.  Ordered this unit and it installed in minutes with no drama.  Did some routine derailleur adjustments and I've put about 120 miles on it the last 10 days.  With one ride being 32 miles with 1000 ft of climb, the cassette shifted flawlessly.  Shifts are MUCH better when the teeth are the right shape :).  I really like the sexy bright finish on old man's bike.

Used this to replace my derailleur on my 2006 Giant Boulder 21 speed mountain bike.  It fit well, but it took a little time to get it to shift right.  Now shifting is smooth as butter.

I'd been suffering from lousy shifting for about a year now, despite re-aligning the derailleurs multiple times, greasing the cables, etc..

Finally I decided to try replacing the 4-year old shifters, and I am very glad I did. These shifters are considerably heftier than the ML530s they replaced, and instantly resolved all my shifting issues.

I bought this to replace a broken one on my 26" kent Devastator fat tyre bmx style mountain bike. The installation was simple, easy to adjust, and works flawlessly. I will definately buy this item again.

Pieced together a bunch some cheap/used 2010 SRAM red shifters and 2012 crank, with a force RD. This YAW FD was the final piece. Works so well/ smooth. I cross chain all day on a 12/25 with no rub at all. Super quiet.

Primarily I needed only the nut and bolt because the derailleur had its own hanger on it.  My son had ridden the bike for nearly 8 years like this, and we had fought with the derailleur every time we'd removed the rear wheel.  Now the derailleur stays in place and there's no more fighting, cause once you've got the nut and bolt, you've got everything.  The hanger seems fine, and I've still got it, in case I need it, but the nut and bolt fit right on my original 1980's hanger (SunTour Cyclone) without a problem.

nice derailleur.  No issues with the quality of the product.  Works as expected.  Was nice to find this older model derailleur.

My old bike's drive train was worn out and I decided that if I was going to swap everything out I might as well give SRAM a try.  I also wanted to try out twist shift to see why they had such a cult like following, well a lot also had to do with them being a hell of a lot cheaper than X0 triggers or even X9.  I a paired them up with a X7 rear derailleur, Sram 970 cassette, cheap KMC chain, a new shimano lx middle chain ring up front, and new cables and housings.  I cut down my old Oury grips and left the old shimano lx front derailleur alone.

The first couple rides I'd twist the wrong way fairly often but that would expected switching from SRAM triggers to Shimano or vice versa too.  After a month of riding with them I'm not yet 100% comfortable with them but I'm getting there.  There has been no ghost shifting and every click is very noticeable by feel and by ear, they are loud.  Being able the trim the front derailleur is nice especially since the one on my bike has never worked worth a damn.  Shifts on the rear are quick and solid and you can twist through the whole cassette easily.  The other nice thing you can do though I haven't mastered it yet is keep a finger on the brake and shift up or down which I couldn't do with the shimano triggers.

Now are they better than trigger shifters?  I don't know.  I never really had an issue with the shimano triggers either. I like the twist shifters so far but I'm not joining the cult yet :).

I purchased this MTB derailleur for my road bike because of the long cage to accommodate my SRAM PG 1050 12/36 cassette.  But I found that actuation ratio actuation ratio was 1.3, which did not match my Shimano Ultegra shifter.  So it went into my storage bin.  Later I found the Wolf Tooth Road Link, which extends the short cage Ultegra road derailleur by about 1 inch lower, so it was able to reach the 36 tooth gear, it it worked just fine.  For the right application this derailleur is just fine.

Although a mini adjuster it works very well on my front derailer cable.

Bought this 'cause I destroyed a Shimano acera by picking up a stick while trail riding. I own 3 bikes all of which have Shimano drive trains---until now. This derailleur shifts really smooth and quick and because it keeps more "tension" on the chain it stops most of the chain slap on rough terrain. Just be fore warned as Sram states in their description of this derailleur--YOU WILL NEED TO PAIR WITH SRAM SHIFTERS--this derailleur has a 1 to 1 actuation ratio most Shimano rear derailleur ratios are 2 to 1 and the shifters are not compatible. But in the end it's well worth the investment.

I purchased this to replace the chain on my GSXR.  It worked great.  I broke the old chain master link without cutting the rivet heads.

The new chain required a few links be removed so I used a dremel with a cut off wheel and make 4 small cuts, shaped like a square, around the pin head.  The tool then pushed the pins out easily.  Like others have said, oil the threads well and follow the directions.  Measure your master link width after pressing and the flares with a digital caliper and it will turn out great!

I am mechanically challenged...so, keep that it mind. It took me two days off and on to finangle this to work.  I have a diamondback commuter bike (serene citi) with large handlebars. Strangely after having a bike shop put on a kickstand and replace my brake cables, my right( back derailler) twist shifter was stuck on "7"...apparently bike shop guy managed to damage my original shifter cable with the new kickstand bolt which was right under the derailler cable.  :(  I really didn't want to trust expensive bike shop repair guy with my bike after that!  So, I researched the twist shifters and realized that I could not simply replace the cable without somehow opening the shifter, I found an access port for the cable, but short of pounding the shifter I could not get inside easily to thread a cable. These new Shimano shifters seem to be the solution so I ordered them.

 The good news is that

1) what a value! 20$ You get nice shifters, cable housings with caps and cables.
2) They are much nicer than my original grip shifter. Easy to move.
3) The rear sprocket indexing was compatible with Shimano Tourney derailler that I have already on the bike.
4) I was able to get this to work and not have to return to bike shop guy for help replacing these shifter cables.

And...did I mention...I didn't know anything about bike deraillers, and I managed to install this. Score!

The bad news
1) the included cable housings were far to short for me to use for either the front or back derailler... by about 10 inches. I had to reuse my old cable housing, which is not ideal, and then the cable attached to the shifter was too short to travel to my rear derailler in the old cable housing.  Annoying, because I don't have the superhuman strength wire cutters necessary to shorten my old cable housing. (It is like cutting through satellite cable). So...if you have a comfort bike/commuter bike with the large handlebar setup please be aware that the cable housings are far too short and the shifter cable itself is at the outer limit of traveling to the rear derailler, In my case it was *just* long enough.

2) They don't include the crimp caps for the end of the cables

3) you have to look up the dealer's manual at the shimano website...it isn't straight forward at all how to find this manual, I ended up searching for the publication code from the user's manual at the website and then found the instructions for install in the dealer's manual.

Another note:

Up shifting  from 2nd to 4th sprocket (in my 8-speed this is from gear 7 to gear 5) is really rough and inconsistent,.but all the downshifts were perfect. I tried finessing the cable barrel adjuster but can't seem to get this consistent. Not sure if this is an indexing problem on the shifter or just a problem with the sprockets on my bike. Or mechanic error :)

And- why mess with something that already works? I did not replace my front derailler shifter control- so I cannot comment on that.  Nice to have it as a backup!

Perfect for adjusting the b-screw when installing the larger 40t cassettes without having to mess with installing an additional derailleur hanger extender.

I purchased the Omnium 175mm crank because it promised to be one of the stiffest cranks available. So far it has not disappointed me. I love the longer crank arms for better torque, but I wish the chainring came in a 53T option. This has been my only complaint. I replaced the 48T ring with a Sugino Zen 53T, and I couldn't be happier. The GXP bottom bracket has some bad reviews on the net for durability, but I wanted to try it for myself on my new fixie build. I cannot comment so far on durability having ridden only 50 miles on my new track bike, but it does feel very solid at the moment. The longer power stroke makes going uphill easier for me. I loved it so much I purchased a second Omnium 175mm to build a second fixie.
