Upgrading the old ride(8 posts)

Upgrading the old rideredge0519
Apr 15, 2003 9:15 AM
My sweetie rides an early 90's Eddy M with mostly DA. I am the wrench, and it becomes increasingly difficult to find parts. She doesn't want to give up the ride, but I have convinced her to upgrade to at least an 8 speed STI group. Now, what do I need to change?--shifters (of course), derailuers, hub (already done, running 7 speed cassette with a spacer), chaninrings?, chain?, anything else?
Also, where is the best place to pick up slightly used DA stuff?--maybe from someone that went 8 to 9 or DA to Campy. Thanks

Why not just go with 9 speed downtube shifters. All you would need are the shifters, RD, and cogs.

Okay dude,

What you are going to be doing will be a walk through hell, but seeing that I did it, I will try and guide you through it.

I am assuming you still have downtube shifters on? Well, if you do, then you need to get boss adaptors for the cables to route through your shifter mounts. A little hard to find but possible.

What you are asking for is a little difficult to accomplish. Only Shimano Sora is 8 speed. So you actually need to upgrade to 9 speed. Unfortunately your hubs won't be able to take the 9 speed cassettes. Hence you can still get 9 speed DA shifters but you will have a ghost shift. Unfortunately this may cause some mis-shifting. So the choice is yours. I recommend that you get a whole new set of wheels because yours are probably way old and need some changing anyways. Plus it is about time you changed your hubs don't you think?

You also need a new chain if you go from 7-9 speed. If you decide to stick with 8 speed then no need for new chain, but again if you are upgrading, then I suggest you get a new chain as yours is probably gone by now......

You will need a new rear derailuer for 8 or 9 speed. You can use a 9 speed D for 8 speed no problems. You should try to keep your front D as you won't be able to find one with the same clamp size..... hence herein lies the problem..... chain rubbing. You will not be able to help this because of the different chainline caused by the additional cog at the rear.

Happy working, if you need any more advice drop a line, if not, good luck....... oh words of encouragement, words of encouragement, once you have completed the job, you will have to love that bike because they don't build them like the use to.

Ciao,
Sean

Thanks. I have already replaced the rear hub with a 9 speed compatible hub-using a spacer with the 7 speed cassette. Where would you look for bosses for the shifter mounts? Front derailuer is braze-on, so clamp size won't be a problem. I will give this a try, as she loves her Eddy!

Hello,

You should be able to find boss adapters at your LBS, I live in Singapore so I don't think I will be able to tell you where to get it.

Looks like you are all good to go!!!! Have fun, and don't look back......

Sean
Just did a similar upgrade but stopped before STIKeeponTrekkin

and posted a few minutes ago. Harris Cycles has those shifter mount bosses and probably any other odds and ends you'll need.

It was worth it for me. Go for it.

The rear hub spacing is the big hurdle, everything else is pretty much a straight bolt up. The 8/9 speed DA thing might be something that you need to think through. 8 speed DA stuff is differrent from Shimano's other 8 speed stuff.

If you buy a new pair of STIs, they will come with the down tube cable stops that you will need. I suspect that most LBS have a drawer full of the things by now. If they like you, it might even be a gimmy.

I'm thinking shifters, cassette and a chain just might be enough to 9-speed it. I'm not really sure about the rear derailleur because I don't speak fluent Dura Ace, but I'm betting the derailleurs you have now will work.

Good luck.
