Tempo vs S12S LTD for 650b

I have both frames, 64 cm. I would like to do a 650b conversion. The Fuji is heavier, Tempo less so. Any experiences with these? I see some where folks have cold set the chain stays for clearances. For clearances, the Fuji seems better

I'd go with whatever has the most clearance tire, but brake reach and bottom bracket height are also key issues. How do those measure up on the two frames?

I wouldn't want to invest in that particular Fuji frame. Not "mid-level" enough.

The Fuji. I'm pretty sure the chainstays are longer, trail is lower, it has better clearances, and it looks less like a racing bike.

Clearances on the Tempo will be tight, although it's a much better frame.

I actually like converting go-fast frames to 650B. It smooths them out but doesn't lose the attributes of lightweight climbing. My Lemond is an example (with 38mm x 650B tires):

I had an 87 Tempo and Fuji S12-s. I converted the Fuji and it was fairly simple with plenty of room for the fat tires.


I had more plans for it but this is how I finished with it.

Very smoother rider and surprisingly fast when I got on it. Built it to use on Sunday rides when recovering from long Saturday rides. Just found I was taking out the Opus III for that purpose more so I sold this locally to a guy who is loving it.

Both. Fuji is a heavy low trail touring bike that will take 42mm tires. The Tempo is a light not low trail race bike that will take 38mm tires. You definatly need both. I have the same frames, so ask me how it all worked out in ten years......

Check the bottom bracket drop. I measured my Tempo, and it was 75mm, which is a little low, especially if you use long cranks. I didn't try to put 650Bs on it. I think you might be able to use sidepulls on the Tempo, but the Fuji might require Dia-Comp 750s, or MAFAC Raids or copies of the latter. I happen to like CP's, especially with brazed on posts . I also like wider tires; I think the Fuji would be a better candidate;

What year is your Tempo?

I was able to put 38mm tires with fenders on a 1985. Rode very nicely.

If you average all the responses out, it looks like you've got to convert both. That's the jury's verdict.

Buy/build the wheels first, buy the long-reach brakes, then try them on both frames.

That's a tough one. Fuji for the smoothness, Tempo for the sprightly ride.

I converted my Lemond Ti. I have 38mm tires, and they are very, very tight. If the wheel goes out of true, I won't be able to ride. I'm not sure I'll keep it this way. Eventually, I will try the wheels on my McLean which has more clearance. I might not even keep the Lemond. It's nice, but maybe it's just not for me.

Yeah. I would like fenders, Fuji would be better. I could rerake the fork on the Tempo for trail. So many choices

I had a 1987 years ago. I seem to remember max tire size being 25mm on that one. I could squeeze in 28mm on my 1985.

On the 1985 pictured I spread the dropouts to 135mm, but no crimping for tire clearance.

Reviving this and thanks to all on comments and photos of conversions. Nice rides
New question: Re-space the rear to 130 or 135mm? I don't plan on exceeding seven speeds in the rear. Chainline issues?

7-speed should only require ~126mm.

True. Thinking about hub choices. Have not sorted out choices yet. I don't need high end stuff.
