In my experience, the Ultegra 10 speed FD is too long to work acceptably with a "touring" crankset. I haven't tried a Tiagra 10 speed FD, but I would have my doubts. The XT FD doesn't work with the Ultegra 10 speed shifters either.

I haven't heard whether the IRD Alpina-d front der works with the Ultegra 10 speed. If so, then the new 10 speed MTB cassettes would
indeed give tourers new (modern?) STI options.

KD: Was your Tiagra FD purchased when Tiagra was 9 speed or is it a new one made when it was meant to be paired with Tiagra 10 speed shifters? "The right combination of parts" is the issue avoided when sticking to a pure MTB drivetrain.

Too old? C'mon
Anybody with a lick of sense can maintain a tapered crank. You can get a better 45mm chainline with the Sugino too, 50mm kinda sucks for a road bike. If you need lower than a 24/34 or 36, I won't say it.......
If the OP wants to go even less expensive, he can get a Stronglight Impact triple for about half of the Sugino. https://www.chainreactioncycles.com/S...=impact+triple

Too much is made out of chainlines. I run 135mm hubs on my touring bike. Most touring bikes are going to use the same hub width which is the same width as a mountain bike. With the exception of one road bike every thing I own runs mountain bike cranks and I've never noticed any kind of problems with shifting or chain wear.
What won't you say about needing a lower than 24 tooth inner? I have no problem with using the smallest inner chainring I can get. I even run a 20 tooth inner on my touring bike. Got a problem with that?

A 44/11 really isn't that tall. It's only 108 gear inch. Even my tiny wife spins out a 44/11 pretty quickly. A 46/11 or 48/11 gives a much better range.

In fact, I think the new 2x10 MTB setups (42/28 or 39/26) with a 12-36 10 speed cassette could be of interest to many tourers. It would be nice to get rid of that pesky triple front der.

Well, at 90rpm, 32mm tires, and a 175mm crankarm a 44/11 gets you 28.9 mph, a 46/11 gets you 30.2 mph, and a 48/11 gets you 31.5 mph. All speeds reached only while descending. Any benefit of the taller combination would be fleeting at best.

You beat me to it. Was just going to say that if your wife can spin out @ 30 mph while loaded with 25 lbs or more of gear attached and she's not descending, and can do it for a sustained effort, she should turn pro.

If you come off a hill onto a flat, you can turn a big gear to keep your momentum going for a mile or two. Back when my only bike was a mountain bike, I had to pedal like mad to keep up with my friends with road bikes in those cases. If you don't need to keep up with anybody, that substantially reduces the need for big gears. And it's never a bad thing to have a 22x34 if you can swing it.
For the record, I have an XT 48-36-26 crankset on my touring bike.

And anybody with a lick of sense can see that the Shimano system is far superior to a 3 piece crankset. There are no crank bolts to work loose if not properly torqued. If something does come loose, it takes a 5 mm allen wrench to fix it. And the Shimano doesn't cost that much more than the Sugino.

A little perspective: for years and years and years people toured on old style square BB cranks, cottered cranks and what not; things coming loose is exceedingly rare and has always been. A little Loctite is cheap insurance, but I'd say that's mostly a non issue IMO.

If you can spare a couple of gears, they have 9 speed versions of the 12-36 cassette too, and I think one could manage that with a 38-48 front, or 36 if you can. I'm going to go this route with a drop-bar hybrid next year.... I should add that it's running that black deore FD with the mega-range just for this reason.

I wouldn't take this bike to the Rockies, but I think it's enough for me and my light gear in the rolling hills of the Great Lakes... and I was one of those plucky 20km a day commuters before I got laid off.
