Good Product

What to say, it works fine. Direct replacement for my 9 speed cassette, slipped right on freewheel without any trouble. Excellent price and service from BTD, as usual.

Excelent Shimano Quality

This cassette shifts smoothly, lasts for many miles, and has useful gearing. Ultegra is high quality and a good value. I have always been happy with Shimano components.

This is a good quality cassette sprocket.

This 12-27 cassette helped more than the stock 12-25 in climbing hills, but not enough, and I got an 11-34 with mountain bike derailleur to do the trick.

This is a good quality cassette sprocket.

I manage to climb just about any hill but slowly and only with great effort.

I got this 12-27 cassette as I through it would make climbing easier than the stock 12-25 cassette. It did, but not nearly enough, so I got an 11-34 cassette and mountain bike derailleur to handle it. The combination did the trick. I'm still no faster on the hills but this gearing definitely is easier on my legs.

High quality 9-speed cassette

Was looking for a 9-speed Shimano cassette with a wider range than the stock 12-25t cassette for an older road bike. This 12-27t cassette offered the lowest cog (27t) that the 9-speed short cage rear derailleur would work with. The level of machining quality is very high as is typical of the Ultegra range of components.

I have several nine speed bikes...

I prefer a Shimano drivetrain for nine speed applications, so I am appreciative for the ease, and low cost, of this Shimano Ultegra cassette. Its exactly what I required for the rain bike. Works perfectly every time.

Great

Have these on all my bikes. Last a long time, shift really well and price is great. Dura Ace is nice too but to expensive for my needs. These ultegra cassettes are perfect.

I have not put this on yet but it was my only option for my 9-speed since I could not find the 15 tooth cog that I needed.
