Drivetrain Components for a Soma Saga build
Hi Friends! I am in the process putting together a new touring build. I now have a dilemma of choosing the right drivetrain components. Originally I had chosen these components:
[table="width: 500"]

[td]BB[/th]
[td]SKF BAS-600 JIS 110mm[/th]

[tr]
[td]Crank[/td]
[td]Sugino XD-600 Crank Triple 46x36x24 172.5mm[/td]
[/tr]
[tr]
[td]Front Mech[/td]
[td]Shimano XT M771 Conventional 9sp 28.6mm[/td]
[/tr]
[tr]
[td]Rear Mech[/td]
[td]Shimano XT M772 Shadow 9sp Long Cage[/td]
[/tr]
[tr]
[td]Cassette[/td]
[td]Shimano HG-50 11-32T[/td]
[/tr]
[tr]
[td]Shifters[/td]
[td]Shimano Dura Ace SL-7700 DT Shifters[/td]
[/tr]
[tr]
[td]Chain[/td]
[td]SRAM PC-971 w/powerlink[/td]
[/tr]
[/table]
But my LBS is saying that XT components won't be compatible with my front crank, and they suggested going with Ultegra derailleurs instead. What are your thoughts on this?
I was thinking if the Sugino crank really doesn't work with XT derailleurs that well, it might be a better idea to go with an XT crank instead of switching the derailleurs? Or is going with Ultegra derailleurs not such a big deal? I heard they were less durable and more finicky, but have no practical experience with them. I also heard that indexed road shifters are not 100% compatible with XT derailleurs, but have seen many a bike with the combo, so who knows on that.
Many thanks!
