I had a Gossamer CX double with 36-46 om my Heckler with no issues that I can remember. Frankenbike build that worked remarkably well for fast XC riding:

Enjoy!!

My commuter uses a 48/34t chainset with no issues what so ever.

I had considered running a road chainset on a mtb with this set up. (well 48, 36 was the smallest outer and middle I could find in 130bcd)

I had presumed that if the cranks / rings etc didnt clear the chain stay you could install a longer BB axle to compensate.

Is that off the mark?

As above, I have one on my road commuter based on an old Klein Attitude frame. Works well with no probs.

how weird. probably something to do with being a e-stay style frame. on my ridgind steel frame the gossomer hit the chain stays

Is it to up the gearing? If so consider a pre compact (mtb) chainset I.E one with a 110mm BCD.

Easier if you're running square taper - I had an Octalink on the Kilauea in the above pic and the longest axle didn't quite clear the chainstay. A gentle application of the rubber covered handle of my claw hammer sorted that one... :shock:

Was great to see the looks on the faces of the Camb's Uni Roadies when the oike on the mountain bike used to tag along for a few miles...

Thanks for all the replies! Looks like it can be done then. I use a square taper BB, and I was hoping to put a double chainset on. Its mainly to make my bike more efficient on roads as I hardly ride off now.

Something else would the triple XT shifter still work on a double chainset???

Thanks again

I used to run a road crankset on my old Muddy Fox when I used it to commute, like We are Stevo said the look on some people's faces when I overtook/kept up.

On the basis that that's what's fitted in the pic of my bike (my daughters' now actually...) above - yes
