How good is Shimano Ultegra?

Ultegra is generally regarded as the sweet spot in Shimano’s groupset range, and with good reason. It’s a bit more polished and a couple of hundred grams lighter than the next step down 105 and nearly the match of top-of-the-line Dura-Ace without the extravagant price tag.

Is Shimano Dura-Ace better than Ultegra?

Although Dura Ace is considered to Shimano’s out-and-out performance groupset, surprisingly, Ultegra is generally deemed to be much more versatile, mainly because of the lower range of gears that it offers. While Ultegra cassettes go all the way up to 34 teeth, Dura Ace cassettes only go up to 30 teeth.

Can a 6700 chain work with a 6600 chain?

My next question is regarding which chain I need. The Shimano compatibility chart implies the 6700 and 7900 chains do not work with the 6600 chainring, however these two chains have now been superseded by the 6701 and 7901. Does anyone know if the 6701 and 7901 will work with a 6600 double chainring and 6700 cassette?

Is the 6700 the same as the 6600?

Of course I’m making the assumption here that 6600 and 7800 and 6700 and 7900 are very similar or the same in design, which is often the case with Shimano’s top two groupsets. The RD will work fine.

Can a 6700 groupet work with a 6600?

Unfortunately I don’t have the money to go out and buy a new Ultegra 6700 groupset, so I’m trying to get some second hand stuff on the cheap, mainly from eBay. I’m wondering if anyone has any experience/opinions if the above will work? I’m most concerned whether the 6600 STI shifters will play nicely with the 6700 brake callipers.

What kind of chains are compatible with Shimano cassettes?

Generally speaking: The easiest way to ensure compatibility is to buy manufacturer-recommended components. Shimano and SRAM 5- to 10-speed cassettes and chains are compatible. Campagnolo is only compatible with Campagnolo and a few aftermarket chains (such as those made by Wipperman) that are clearly labeled “Campagnolo compatible.”.
