105 gruppo durability
I just got a new Cdale tandem with a Shimano 105 sti 9sp triple gruppo (that's a new 2003 model, for those of you keeping score). The stuff seems fine to me, but I've been racing DuraAce for so long that I thought I'd ask about it. Is 105 reasonably durable? The cranks are hollowtech which is pretty good stuff, and the levers shift all right. Rear der. Is Deore XT. It works fine, definitely not as sooth as DA, but pretty nice. I don't want to spend a lot of money on an upgrade for nothing....
