Shimano CS-5700 105 10-Speed Cassette

I was getting a little depressed with the whole 10-speed Campy compatible / Shimano freehub cassette situation. Several years back I had a Bob Jackson frameset built and shipped to me in the US. At the time, I favored Shimano hubs because they are high quality, have serviceable bearings, and don't cost an arm and a leg. However, there is nothing quite like the 'crispness' of Campagnolo drivetrains. So I opted for a cassette by Ambrosio that was Shimano splined, Campy spaced. These work great, but for some weird reason, you can't find these in shops in the US. You can find them sometimes on Ebay, but otherwise you have to order them from bicycle shops in the UK. The quality of the Ambrosio cogs is not super-great, so they have to be replaced each year or year-and-a-half or so in my case. So I started researching whether or not you can just take a Shimano set of cogs and use the Campy specific spacers to have a working set of gears. It turns out you can! I have an older Leader 722-RS frameset built up with Shimano 105 components. When I ordered a replacement cassette for that bike, I took off the old Ambrosio cassette on the Jackson frame and threaded these on with the Shimano spacers. The hubs are Ultegra, so no problem. The shifting was awful... but I noticed that at the top of the cluster (largest cogs) the shifting was good... this is important because these first three cogs are a welded together unit, so you can't tinker with the spacing. The derailleur had to be tweaked to allow more travel and the cable tension had to be adjusted, but the indexing was spot on at the top of the cluster. The middle cogs used four Shimano spacers and the shifting clearly didn't line up. Also the bottom of the cassette (smallest cogs) seemed out of joint, but nothing was that far off. The Ambrosio cassettes come with a total of 6 spacers, so I swapped out 4 of those for the four Shimano spacers... tweaked the cable tension, adjusted the high/low setting on the derailleur and it worked. You could have knocked me over with a feather. I've seen spacers sold separately for Campagnolo (blue in color) and I assume these are the same as the yellow Ambrosio ones (same spacer width). The quality of the 105 cassette is a little better than the Ambrosios, so I think these will hold up well. The quality of the shifts is a big improvement too, but these are brand new... I don't know if that will hold up over time. I've only ridden this set up for a few miles after initial set up, so if my chain explodes (a ten speed specific KMC chain) or the cogs fall off or something, I'll post a follow up.

Shimano 105 is such a workhorse level of componentry! Sure, it’s heavier than higher end gear, but the difference is negligible for most cyclists and the durability is fantastic. Besides, the price is usually a fraction of the price of Dura-Ace or Ultegra!! Highly recommend.

Went to a bike shop to change up my cassette..those crazy people wanted to sell me the top of the line $300 cassette. NO THANKS. This one works great! I have a dura ace shifter & this cassette works perfectly with it. I've had a lot of hilly races and haven't had an issue. It's a great & cheaper alternative than the $300 over the top of the line stuff. That is as long as you don't care about carrying like .05oz more in weight.

I purchase all my parts on-line and bring them to my local bike shop to install. I get charged labor and that is it! Why pay double the price for parts when you can save money. Just check with your shop, provided you are not doing the labor yourself and whether they will not have a problem with this. Go elsewhere if they have an issue. Make sure you get a chain that is compatible with a 10 speed cassette. I picked up a KMC X10.93 10-Speed Chain at BikeTiresDirect on-line for less than $25 and it works as well as any of the most expensive chains. Don't waste your money on Shimano bike chains. I like this Shimano cassette so much I purchased another and intend to keep buying them as long as I have this bike.

The Shimano 105 10-Speed Cassette's just what I'd needed for my rigid MTB as well as my Elite indoor trainer. Its relatively narrow overall 10 cog design works well for me on training rides on flat or rollers; allowing gear ratios easy to dial in. When in combo with a 36T chainring on a 1x drivetrain, selecting the right ratio for a desired cadence and power output is a click or two away at most depending on terrain and/or training segments. Thanks to a super-sweet chain line on the sweet-spot of this cassette (which I use for most of my rides), it's literally dead quiet... quite the stealth.

Fast shipping, great all around set of gears. Good o flats and hills. 73 years old and find the 11-28 great on hiss and flats. Shifting could be better under stress but partially operator error not shifting on time. Ultegra May be better for that. I may upgrade for that reason as as the difference in price is slight.

Good quality

My local bike shop was not going to be able to get this for another four to five months so I ordered this cassette and received it in just a few days. Good quality and was able to start riding again quickly.
