Subject: Zipp compatibility issues - need help!!
i MESSED UP BIG TIME....
I got my hubby Zipp 404s for our anniversary...and thought I had checked everything...but, I took them into the bike shop today, and turn out, there is a 9 speed cog (I dont knowe if I'm using exactly the right words here) on the back wheel...I thought that it could just be switched out for 10 speed, but turns out, it can't...

so, my question is - does anyone know if I can get a new (longer) hub that is 10 speed compatible to put on the back wheel, and then just get the 10 speed cogs to go on it, and I guess true it to work...or do I have to sell them and get him a new set of wheels that are 10 speed compatible?

Again, I just had no idea that this would be an issue, very sad about it

Hi !

I bought a pair of 808's with a 10-speed shimano cassette and changed it for a 9-speed shimano (shifters on my bike being 9-sp). I don't know f you can do it the other way (from 9 to 10) but I would guess it is possible... I'd go check with another LBS if I were you... Plus, I know that you can buy a new zipp cassette body (http://www.zipp.com/OnlineStore/Accessories/tabid/58/CategoryID/4/List/1/Level/1/ProductID/5/Default.aspx?SortField=ISBN%2cISBN) w/o having to change the entire hub. Hopefully, you'll be able to put a 9-sp compatible cassette body if all else fails...

 

Good luck !

 

Christian.

P.S. On Zipp's website, if you want to order a cassette body, you don't have to specify whether it is 9-sp or 10-sp, which tells me that it should accept both... Unless you own an old version of Zipp wheel. There is a note about it....

The wheels are the dimpled sersion from 2005...from what I read, I think that they are the later 2005 version, but I don't know for sure...the back wheel had a 9-speed on it, and my bike shop said that a 10 speed wouldn't fit on it cause it didn't have a spacer on the 9...if that makes sense...

hubby's bike has a 10 speed Durace on the back...

Is his DA 2005 or earlier?  If so, you're stuck...I'd go back to Zipp...they'll likely swap the wheels if they haven't been ridden.

If the DA is 2006 or later, it should be compatible, and just require 'normal' adjustments. According to Sheldon Brown.

Just to make sure Im understanding -

You purchased a set of 404's that currently have a 9 speed cassette installed on it

You want to install a 10 speed cassette

Your LBS said you couldnt do it because the 9 speed cassette didnt have a spacer

Youre wondering what you need to do to get the wheel to accept a 10 speed cassette?


Take the 10 speed cassette of the wheels that he is currently using (or buy a cassette specific for the 404). When you slide the cogs off you will notice small spacers behind some of the cogs (there is usually 3 or 4). There should be another one behind the largest cog. Take all of the cogs and put them on the 404 in the reverse order that you took them off. Keep in mind, that small spacer that was behind the largest cog needs to go on first.

If you decide to do this you will need a few tools but it is a simple job.

Im using 2004 version of 404s and have no trouble using a 10 speed cassette.

I tried to read through that website, but to be honest, I didn't really understand much of what it was talking about...

He got the bike last year on ebay...
It is a trek, all durace...I guess it is newer??

Jase -

Yes...that's exactly what I'm asking...
So, are you saying that the 10 speed WILL fit directly on the 9 speed hub?
Just try it??

Cause the bike shop said that the 10 speed wouldnt (but they also said that they've never dealt with Zipp wheels before)...we do have a zipp dealer in town,but I'm really not a fan of that bike shop...

The wheels have Zero to do with it. Per Jase, it's all about the hub and spacers. The hub should be fine...the spacers, Jase has given you the how-to. I think you're good.

BTW...editorial...your LBS should have been all over this. This isn't rocket science, for a good wrench....any other shops nearby?

Yes it will fit. Zipp offers their hub in 2 types Shimano and Campy they do not offer 9 speed or 10 speed hubs. Some of the older Zipp 400 may not fit a 10 speed cassette but yours will.

Check out this picture. Notice the ring in the plastic bag, that is the spacer I was referring to in the other post.

Jase-

The first thing my biek shop did was take the cogs off to look for a spacer...he said that there was no spacer there, and that's why to 10 speed wouldn't fit...

does that make sense?

Also, the wheel is the dimpled Zipp 404s...so I'm pretty sure its 2005 with that- right?

Call around to the other shops in your area and ask if any of them have a spacer for a 10 speed cassette. Ive lost one before accidentally and it wasnt an issue to get a new one.

As far as the year of your wheels 2005 sounds about right when they started making them with dimples. Im not sure though. If you can find the serial number you can email zipp and they will tell you.

As others have said here, there shouldn't be a problem swapping a 9 seed with 10. The 10 speed cassette requires a spacer, but it comes with the cassette not the wheel. Are you saying that the LBS pulled the 10 speed cassette off of your hubby's existing wheel and it didn't have a spacer? Even if this is the case, I would expect a decent LBS to either have one lying around or be able to order one.

I'm wondering if the LBS knows what they are doing... Do they sell road bikes? I had a LBS in a previous city that I lived in that mostly had mountain bikes. The mechanics didn't seem to have a clue about road bikes.

The bike shop took the 9 speed cogs (that was on the zipp) off in order to look for the spacer...he said that since the 9speed didn't have the spacer that a 10 speed wouldnt fit on the hub...

They never took the 10 speed cogs off my husbands other wheel, cause they said it wouldnt fit...so the 10 speed has the spacer too?

From what you are saying, it seems like the cogs should be compatible either way because the hub is 9/10, right?!? i guess they just didn't know that...

They guys at the shop are really nice, but they dont deal with many road bikes...the 2 shops in town that do are really not my favorites...

That is the problem. The 9 speed do not have a spacer. My suggestion would be to find another shop. This is a very basic mechanical issue. Or better yet, invest the 40.00 in the tools and learn to DIY, I promise you it is not hard.

Not "too" because the 9 speed doesn't have one at all.

While it sounds counterintuitive, the 10 speed Shimano cassette is actually a little bit more narrow than 9 speed and therefore requires a thin spacer spacer to fit the 9/10 hub. 9 speed cassettes do NOT have the same spacer, which is why they didn't find it.

All they should have had to do was remove the 9 speed from the Zipp, remove the 10 speed and spacer ring from the old wheel and swap. It's a 5 minute job at most and very elementary. In fact, I'd be surprised if the LBS even charged for the service.

Another option would be to sell the Zipps really cheap on the internet because they are "defective." I'd be interested

Actually, you can order a lockring removal tool and sprocket removal tool (Spin Doctor brand) from Performance Bike for under $11 + shipping. Assuming that you have a large crescent wrench in the toolbox already, it should be under $20 total.

I highly recommend learning to do this. It's very easy as Jase714 promises above as long, as you have the tools.
