Mountain bike converted to road?(7 posts)

Mountain bike converted to road?Bill B

I had a large 22" raleigh m-40 frame, alum. with cromo fork, which was in excellent shape that I picked up for cheap. I was just going to make it into a commuter but ended up putting drop bars, bar end shifters, 1" tires, etc to make it into a poormans road bike. My question is, is it worth it to try to put 700c wheels on it? It has a 1 1/8" headset and I see that they are putting out carbon forks in that size and thought I could switch out the fork and I put my wifes rear road wheel and it looks like a short reach road caliper would work fine on the back end. Anyway this will probably cost $300 (which I might be able to pick up a used road bike for) to do and I'm not sure what all the advantages of running 700c wheels are other than the ability to run the narrow tires. It is a very nice looking frame and the geometry seems to be very similar to most road bikes I see. Any advice on the subject would be appreciated. Thanks!
no advantage to 700c , and swapping's a major painCory

There's such a wide range of tires available in 26-inch, from huge knobbies down to 1.0 slicks, that I don't see any reason to go to all the trouble and expense of swapping. Try some hard, skinny tires and watch how that sucker rolls. Plus you still have the option of converting back or using a mid-size or combo tire if you change your mind (I like Ritchey Cross Bites in 1.4 inch).
I've run road tires down to 1.25 on both my mountain bikes with no wheel compatibility problems, if you're worried about that. Never tried the 1.0s, but only because I don't want to go that narrow. I'm pretty sure they'd work.

I'm not sure of what you are referring to?
I wouldn't do it...TJeanloz

While you might be able to squeeze a 700c wheel into a MTB frame, it's not a good idea. The primary objection is that the geometry of the bicycle frame was designed around a 650c wheel, and changing that is going to do weird things to the handling characteristics of the bike. Things like position of center of gravity are very important to how a bike handles, and would be completely changed with a different wheel size.
Good point, thanks!nmBill B

But it's definitely not worth going to 700c wheels in such an application. Quality 1.0 X 26" kevlar bead tires are available for MTBs from Specialized, Ritchey, and Conti. They are extremely good tires with very low rolling resistance. I used a road triple crank to get my gearing up to a useable level, and the bike works quite well. I did something else a little different that paid off very pleasantly. I used a RS Indy SL fork with Englund air cartidges. This fork is very light and extremely adjustable and makes the bike very comfortable and quite unique.
