Bicycle Question, Experts?
 

I posted a while ago about an uncomfortable seat on my old school Cannondale mtb. I have since resolved that proper, and decided to start riding again.

My wheels were old and banged up, so I decided to pick up two new ones. The front is pretty self explanatory. I also upgraded to a mechanical disc brake, which took some adjusting since the brake/shift levers are older Shimano XTR all one piece units.

My question is, after taking the rear cassette off (a 7 speed Shimano Hyperglide one, albeit not exactly new) it is too short to fit on the new wheel. There is about 1/8th of the hub showing. I am guessing the new wheel is made for an 8 or 9 speed cassette. Is there a spacer or adapter I can use, or should I just take the wheel back?

I haven't really ridden it much since I had the Fox terra logic shock put on the front, man is that thing sweet.

Thanks,

You can just get a spacer.

Or use it as an excuse to upgrade to a 9-speed rear. And new 9-speed shifters. ;)

It's a bottomless pit if you go that route...

Thanks Jeff, I am not sure I want to go that route, those shifters are damn pricey.

Sure is. :rolleyes:

Before you invest a whole lot of time or money into this, make sure that a 9 speed wheel will fit in your frame...

Go ahead... Ask me how I know about this one...:rolleyes:

For the record - it was a Cannondale.

there is a 5mm spacer you can put on before the cogs that will take up the extra room that the 8/9sp need.

I agree Angela.

Fortunately I only spent $2 on the spacer. The alignment was all messed up, and it didn't work, so I just won't use the new rear wheel...

Don't let an unconfortable seat keep you from riding. Life is too short.
Look into split-seats, which take pressure off the pelvic nerve.

You did better than I did... I actually bought a 9 speed wheelset, shifters, etc., and THEN figured it out. :rolleyes:

Didn't even get as far as chain alignment, etc. The wheel wouldn't fit in the frame!

My wheel fit in the frame just fine, I just don't think I could have adjusted the rear derailer enough to get to all of the gears.

No biggy. I am going to hold onto the wheel, I got a pretty good deal on it, and down the road when I finally do upgrade to a new bike, I will have a spare.

I kind of feel like the guys that throw a 3.6 in an earlier car. Older frame with all kinds of new componets...

Thanks,

Bill

They should all use the same width hubs.
7 and 8-speed cassettes use the same width gears and chains, but 9-speed gears and chains are narrower. So you should be able to switch to an 8-speed rear-end (cassette, shifter, derailleur) without changing chainrings.
Old C-dales are cool... got any pictures?
