Verification: 7 to 8-9 speed...funknuggets

Would it be cheaper for me just to get a new hub and have a wheel rebuilt or to get the 8-9 body and get a longer axle... and just basically rebuild the hub???

The cheapest way that I've found to convert to 8/9 is to tear the axle, bearings, and freehub off of an old rear 8/9 mountain wheel. You will likely have to take some material off the end of the axle to not exceed the dropout width though. Old mountain wheels are typically much cheaper to buy and fail more frequently than old road wheels.

Hope it helps!

First, check what you have now. Lots of 7 speed road bikes were built with 130mm spacing. If that's the case, a new freehub body, messing with the spacers on the left side of the hub, and redishing the wheel is all you need.

If your bike's dropouts are spaced 126mm now, it's still going to be cheaper to rebuild what you have. If you pay full list retail, a 105 freehub body will cost about $30.00. A 105 axle set with the right length axle and all of the correct spacers and cones is $22.00. Besides rebuilding the rear hub, you'll also have to redish the wheel.

By comparison, I'd charge you $32.00 just to relace the wheel plus $16.00 to $32.00 for spokes and you'd still have to buy a hub.

If you feel you are competent to do the work, It looks to me like Quack's idea would be a winner. Mountainbikers eat up rear wheels. You'll probably need a hacksaw and a bench grinder to cut 4 or 5mm off of the mountain bike axle which was designed for 135mm spacing.

Cool, it is 130!!! I will get a new freehub body and adjust the spacers and redish. Thanks!
