Touring bikes with front Doubles

Hi - I am looking for a bike with all the characteristics of a decent touring bike but with a double chainring in the front. Does someone make a bike like that?

Salsa Vaya fits the bill:

I test rode one last year, it seems like a great bike.

I don't know of a specific bike that comes like that but it is easy enough to change the crank. I would look for a bike that comes stock with a mtb rd and cassette as you will probably want that if you plan to use a compact in lieu of a triple.

If I bought my LHT as a complete bike, it would have come with a triple up front, but I built it from parts and a double suited my needs much better. I think there are good reasons why triples are used in terms of gear steps and shifting patterns, so you might not find a stock touring bike with a double, but it's not a difficult change to make.

No, but conveniently enough nearly every decent touring bike has a triple and like Booger! said "Take the outer ring off and put on a bash guard,instant double crank."

Which is what I did for my Cross-Check and LHT but eventually changed the LHT back to a triple with a relatively close range 12-28 8spd cassette.

The CrossCheck has a 74/110 BCD triple with the outer ring taken up by a Salsa chain guard. Middle ring is a 44t with a 30tooth on the 74BCD inner ring position. With that I can use every cog on the cassette as it's the middle ring and the inner is a low gear. If I want a lower range than the 30chainring I can put a lower chainring on and a wider cassette. 44/30 w. 12-28 8spd gives a 29"-99" range. If I drop the inner to 28t and the cassette to a 12-32 I get 24"-99" range.
For touring I could see a 9 cassette giving all the gears you'd ever need w. 26/44 chainring and 12-32 cassette for a 22"-100" range

My thoughts on gearing. The "recommended" range for loaded touring is 20 to 100 gear inches. How you get that is up to you. You can use a triple with a cassette that has fewer big jumps between gears, or a double and a really wide mt. cassette. Your call as to your own needs. I like smaller gaps between shifts in the rear, saves the knees when on day 3 of a headwind across the prairie. Thus I use a triple and a tighter cassette.

Taking the small ring off a triple make no sense as it's usually the large ring you don't need. This is very dependent on what crank your using. If it's a typical 105 or Ultegra triple, it might have a 30/39/52. In that case I'd rather have the 30 then the 52 and would swap my cassette to start at 11 or so to get that 100 inch high. I also swap the 30 for a 24 or 26 (the 26 works better) to go low, but again, your call.

The typical road compact uses 110bcd rings and usually has a 34 small and a 50 large ring(s). With the widest range Shimano cassette you get a 34 large cog. That's a 27 gear inch low and may not be low enough. So do you swap the 34 small ring to get the low gearing or stay with a triple ?.

Triple.

No, You have to do that , yourself, rather uncommon components ,
for a mass produced rig. you have to swap components.

A touring companion in 1986 had a TA cyclotourist double a 50/28 combination.

collectors stuff, now.. the crank-arms sell for $200+, now.. minus chainrings
but replacement chainrings are sill made.

On my Brompton I have a double chainring , but the granny gear is a planetary .

as if a 50t, 20t.. , but can be shifted at low or no momentum..
Schlumpf Mountain drive crank , turned my 3 spee into a 6 speed using it 's
gear ratio's twice, once again in low range.

The Salsa Vaya comes with a 50/34 compact double. Not really uncommon....

Most 'cross bikes have doubles, and many are pretty close to same manufacturer's touring bike geometry. So, for whatever touring bike you like, see what their cyclocross bike has.
