Ultegra rear cassette/derailleur for Tiagra(6 posts)

Ultegra rear cassette/derailleur for Tiagranealrab
Aug 5, 2002 8:37 PM
Starting on Giant OCR 2 (nice bike) but someone offered me an Ultegra rear cass and der at a deal price- does it make any sense to change out rear assembly from Tiagra to Ultegra
on this bike and retain the Tiagra components on shifters, front der, crankset? Will I gain anything by doing this?
Don't really want to spend a lot for full upgrade of all components at this point. Or I'd have gotten a TCR 0. It is a triple set, 9 spd. Using bike for training now.

ultimately, save up for a TCR frame (or some other nice frame). I do think that changing the cassette and derailleur to Ultegra will make a difference in shifting, however.
Component upgrades seldom make economic sense.Spoke Wrench

Exceptions include:
1. When something breaks or wears out and has to be replaced anyway.
2. When somebody gives you parts or you already parts that you want to change.
3. When you get so much enjoyment from the process of upgrading your bicycle that you don't care about the economics.

I fall into the third catagory. I'm constantly making changes to my bicycles just for the sake of doing it.

A couple of other points to consider.

I've often said that I can't tell the difference if I move up up or down just one Shimano group, but I can tell the difference if I move two. By this logic, you should experience "crisper" shifting with the Ultegra derailleur.

The Ultegra cassette, it it really is an Ultegra cassette, will be noticeably lighter in weight than the comperable Tiagra unit. The problem is that new bikes often come with mostly Ultegra components, but cheaper cassettes. The guy who is selling it might not know the difference.

Make sure the Ultegra rear derailleur is the long cage, triple version. Otherwise, it won't have enough chain slack take up capability.
