8spd...need 9 or 10....not sure of compatability?

All right.

Sorry - I meant 8 spd, not 7 speed. Thanks!!!


I know this is a rookie question and I will take any flac you send my way, BUT please just help me with the question.

I have a Allez Triple. Comes with a mix of Sora and Tiagra. I bought some Mavic Ksyrium Elites, but they only work with 9 or 10 speed. What is the easiest way to upgrade? Can I just buy a new cassette or will a new derailer and shifter be required?

Not looking to spend $800 to upgrade the componants. Just not in the cards right now. Thank you for all your help and happy riding!

The brifters are going to cost a lot, in addition to needing a new cassette and chain. Probably too late, but check compatibility before purchasing wheelsets with your current setup.

Shimano Tiagra 9 speed brifters are $180 CAD. Chain + Cassette add around $60 - $70. All that for one more gear in the back.

This could be a good time to upgrade to 9 speed 105 brifters, which are on sale now since they're being discontinued. You're taking a risk re: future cassette availability, but I'm guessing it's not going to be a huge problem (and by guessing, I mean hoping, since I have a 9 speed 105 setup right now).

Nashbar has a sale on the 105 brifters now. Cassette is not too bad either......why not, huh?

Most wheels work with 8/9/10 speed cassettes since the total width is identical although sometimes the 10s need a slim spacer.

all you need is a spacer, and you can use thema as 8 speeds with no changes

I had to research this for a similar problem this morning. Sheldon Brown once again comes to your aid. Study the following and talk to your LBS:
