"In the end it worked fine but the product arrived and the packaging was cut and looked like it was a return."
"works very well - stronger than Dure Ace it is replacing."
"worked fit nicely but I probably should have gotten the 11-30."
"Can't go wrong with Shimano quality, very nice gearing, if you don't climb a lot if hills, the 12-25 is a really good gearset."
"I bought this cassette as I already had one on my original wheel-set and wanted the same on my second wheelset."
"Part of an upgrade from Shimano 105 to full Ultegra compos."
"Works like all Shimano parts."
Shimano's Ultegra-level cassettes are one of the gems of cycling components. A more rigid aluminum carrier keeps the cogs in check when making shifts under load.

Find Best Price at Amazon"I replaced my old ten speed 12T-27T cassette for this 11T-28T for easier (less leg muscle effort) long up hill rides."
"My tires are 700-28c & 23T at 85 cadence (34 chain ring) is 10mph (as slow as you can go) so it's not for the steepest of hills but it's perfect for rolling hills riding to keep cadence steady."
"I know most people say they get more miles out of a cassette, but I was not diligent about keeping my chain clean, and so the chain and the cassette got worn pretty bad after 2,500+ miles."
"The 12-30T provide me with one lower gear on both the high and low gearing."
"One great cassette and great combination (12-23) for flats ironman distance, loving the gear 18 so much."
"It is also recommended to use a sprocket removing chain wrench Like the Park Tools SR-1. In my case installed without the spacer the inner cog ran into my plastic spoke guard."
"Shimano quality with lasting quality."
"There are several cassettes that are lighter weight and may shift just a little bit better but this cluster shifts really well and I believe has about the best cost performance ratio out there."
Our new cogset features a semi-spidered construction for a maximum stiffness to weight ratio and is available in seven optimized configurations to best match a wide variety of uses. Specifications Weight: 359 grams (12-36) Gear Ratios: 11-23, 11-25, 11-26, 11-28, 12-25, 12-26, 12-27, 11-32, 12-36 Speeds: 10 Recommended Chain: PC-1090R, PC-1090, PC-1070, PC-1050, PC-1030 Sprockets on Spider: 3 Lock Ring Material: Forged 7000 Series Alloy, Anodized, Laser Etched Sprocket Material: Heat treated steel / Blast Silver.

"I wanted a lower gear and got the SRAM 12-32. MIGHT be able to squeeze it on but you'd need a larger chain for sure and then in the lowest-lowest combo the short cage RD would be rubbing so you'd need a long cage version."
"I only had one small problem where I had to add some of my old spacers between the cassette and the hub so it would not wobble."
"This review based just on closely examining the cassette, then assembling it, installing it, installing a (new) chain, and testing the shifting with the bike on a stand."
"The SRAM PG1070 cassette is exactly what I needed to create a climbing machine out of my road bike."
"I purchased the Sram pg1070 cassette to replace a stock Shimano Tiagra cassette on my new bike."
"I prefer the gearing combination of this cassette to a mountain/MTB cassette of the same gearing range."
"I had a 15-25 cog set previously which just wasn't cutting it in the hills."

"I suggest using the nut from the old spindle to tighten the new crank-arm onto the spindle. Then remove the nut and attach the lighter weight allen screws which come with this spindle."
"this was the best deal i could find for sprockets to add to my ebike motor, especially ones with a 104mm bolt spacing."
"Not to hard to install."
"The taper was slightly larger than the one I replaced."
"Went with the Shimano Acera FC-361L 42-32-22 175mm (EFCM361E222XL) crankset to replace a Suntour XR180 42-34-24 170mm crankset I had on an older bike (mgx d50i)."
"Bought this to replace an existing crank-set on a Giant mtb that was worn out thru lack of chain maintenance( make sure to replace that worn out chain!"

Find Best Price at Amazon"While the tool can be used to put the pin back in (if the pin isn't completely out), I found it easier to just use a hammer. I would not use this tool to put back a standard link while on a bike because of the bending."
"Either way it took about 30 seconds to figure out how to get the chain off, and about 120 seconds to figure out how to get it back together so win win and its well build."
"Well, it was easy enough to remove chain links with this thing, but there were no instructions included with it at all, so I couldn't figure out how to use it to reinstall the pins into the links."
"I put my Kindle Fire on bluetooth speaker and listened to Josh Turner as I replaced the front deraileur."
"This tool worked very well and pushing the pin back in to secure the links."
"From the integrated piece of curved wire to hold your chain while you insert the pin, to the adjustable link holder (probably not the technical name), this made short work out of what is usually a chore."
"Not only did it cut the chain easily and cleanly, but with a little care, and a needle nose pliers to hold the pin, I was able the mend the chain as well when it turned out the missing links, despite being the apparent correct size, did not work."
"I was worried about the durability of this tool, but I haven't been disappointed yet."

"I modified an old 80s Stumpjumper into a a 1x9 commuter with modern derailer, but the chain kept popping off during upshifts."
"Works great, have not had any chain drops since installing this."
"Is does the job for the most part, I still dropped a chain and tho flexed enough to allow it to pop off and it was a nightmare getting back on."
"This part was to replace the original one on my son's mountain bike."
"Worked as described."
"does its job, one crash and i bent it but that is probably just because of the way i crashed."
"Unfortunately the inner plastic part of the guide broke off after only a few miles."

"I do suggest a size down with less teeth if you're biking in an area with steep hills, this is more for a moderate or flowing hills type biking, but I can't think of needing one bigger than this, but get a size based on your biking style or your area (Moab definitely smaller!)."
"Put a 43t on my specialize sworks with 12 / 27 cassette super smooth didn't have to do anything but put on race face and ditch the front derailer works great with original dura ace short cage rear derailer. Not having the front derailer on a road bike is super nice especially at race pace."
"The trails I rode on are pretty mellow, but there have some slow and fast rocky downhills, a few drop offs and small jumps."
"I recently purchased a Diamondback Line MTB, and it came with a junk chain guide and tensioner."

"Just what I expected, good price, fast shipping, the products in perfect condition."
"If you do your own maintenance, get this, just don’t second guess it."
"I ended up being int he middle of a redo of the crank and bottom bracket, and was stuck after finding that the tool I has wasn't the right one to pop the old bearings out."
